Comparison of clinical and radiological characteristics of inflammatory and non-inflammatory Rathke cleft cysts. Jpn J Radiol 2024:10.1007/s11604-024-01641-0. [PMID: 39162782 DOI: 10.1007/s11604-024-01641-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2024] [Accepted: 08/07/2024] [Indexed: 08/21/2024]
Abstract
PURPOSE Rathke cleft cysts are commonly encountered sellar lesions, and their inflammation induces symptoms and recurrence. Cyst wall enhancement is related to inflammation; however, its range and frequency have not yet been investigated. This study aimed to investigate the clinical and radiological differences between inflammatory and non-inflammatory Rathke cleft cysts. METHODS Forty-one patients who underwent cyst decompression surgery for Rathke's cleft cysts between January 2008 and July 2022 were retrospectively analyzed. Based on the pathological reports, patients were divided into inflammatory and non-inflammatory groups. Clinical assessments, endocrinological evaluations, cyst content analysis, and imaging metrics (mean computed tomographic value, maximum diameter, mean apparent diffusion coefficient [ADC] value, and qualitative features) were analyzed. Receiver operating characteristic curve analysis was performed, to determine ADC cutoff values, for differentiating inflammatory group from non-inflammatory group. RESULTS Totally, 21 and 20 cases were categorized into the inflammatory and non-inflammatory groups, respectively. The inflammatory group displayed a higher incidence of central diabetes insipidus (arginine vasopressin deficiency) (p = 0.04), turbid cyst content (p = 0.03), significantly lower mean ADC values (p = 0.04), and more extensive circumferential wall enhancement on magnetic resonance imaging (MRI) (p < 0.001). In the inflammatory group, all cases revealed circumferential wall enhancement, with some exhibiting thick wall enhancement. There were no significant differences in other radiological features. The ADC cutoff value for differentiating the two groups was 1.57 × 10-3 mm2/s, showing a sensitivity of 81.3% and specificity of 66.7% CONCLUSION: Inflammatory Rathke cleft cysts tended to show a higher incidence of central diabetes insipidus and turbid cyst content. Radiologically, they exhibited lower mean ADC values and greater circumferential wall enhancement on MRI.

Endonasal endoscopic or endoscopic-assisted transcranial surgery of Rathke's cleft cysts: does the approach and surgical technique influence the radicality and recurrence rate? Neurosurg Rev 2024; 47:403. [PMID: 39102078 DOI: 10.1007/s10143-024-02545-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 06/13/2024] [Accepted: 06/30/2024] [Indexed: 08/06/2024]
Abstract
OBJECTIVE Resections of symptomatic Rathke's cleft cysts (RCCs) are mainly performed via an endonasal transsphenoidal approach. However, there is a lack of equivalent data in current literature concerning transcranial keyhole approach in the treatment of RCCs. In order to find general recommendations for the surgical treatment of RCCs also with regard to recurrence, the object of this study is the analysis and comparison of both techniques. METHODS Twenty-nine patients having been surgically treated between January 2004 and August 2019 were retrospectively analysed. The transsphenoidal approach was chosen in 16 cases and the transcranial keyhole approach in 13 cases. Both surgical techniques were analyzed and compared concerning preoperative symptoms and cyst characteristics, complications, surgical radicality, endocrinological and ophthalmological outcome and recurrences in patients´ follow up. RESULTS The postoperative outcome of both techniques was identic and showed highly satisfying success rates with 92% for neurological deficits, 82% for endocrinological dysfunctions and 86% for visual deficits. In contrast, momentous postoperative complications were significantly more likely after transsphenoidal operations. After a mean follow-up time of 5.7 years, the recurrence rates of both cohorts were the same with 0% each. CONCLUSIONS Regarding its equal outcome with its lower complication rate, the authors suggest using the supraorbital keyhole approach for RCCs whose anatomical configuration allow both techniques. Yet, the decision should always consider the surgeon's personal experience and other individual patient characteristics. Further studies with higher numbers of cases and longer follow-up periods are necessary to analyse the effect of the selected approach on recurrence.

Abstract
PURPOSE The study intends to clarify the optimal endoscopic endonasal surgical strategy for symptomatic Rathke's cleft cysts (RCCs). METHODS We retrospectively analyzed patients with RCCs that underwent EEA surgery. The strategy for surgical and reconstruction method selection was presented. Patients were split into groups of fenestration open or closed. Pre- and postoperative symptoms, imaging, ophthalmologic, and endocrinologic exams were reviewed. The incidence of complications and the recurrence rates were determined. RESULTS The 75 individuals were all received primary operations. The fenestration closed group contained 32 cases, while the fenestration open group contained 43 cases. The median follow-up period was 39 months. The three primary complaints were headache (n = 51, 68.00%), vision impairment (n = 45, 60.00%), and pituitary dysfunction (n = 16, 21.33%). Of the 51 patients with preoperative headaches, 48 (94.12%) reported improvement in their symptoms following surgery. Twenty-three out of 45 patients (51.11%) experienced an improvement in visual impairment. Pituitary dysfunction was found improved in 14 out of 16 individuals (87.50%). There was no discernible difference in the rate of symptom alleviation between both groups. There were three patients (3/75, 4.00%) had cyst reaccumulation. One of them (1/75, 1.33%), which needed reoperation, was healed using pterional approach. In term of complications, cerebral infections occurred in two patients (2/75, 2.67%). Both of them recovered after antibiotic treatment. No postoperative cerebrospinal fluid rhinorrhea occurred. One patient (1/75, 1.33%) in the open group experienced epistaxis. There was no persistent hypopituitarism or diabetes insipidus (DI). Analysis of headache related factors showed that the presence of wax like nodules was related to it. CONCLUSION RCC was successfully treated with endoscopic endonasal surgery with few problems when the fenestration was kept as open as feasible. Preoperative identification of T2WI hypointense nodules may be a potential reference factor for surgical indication.

Childs Nerv Syst 2024; 40:1367-1375. [PMID: 38240786 PMCID: PMC11026193 DOI: 10.1007/s00381-024-06277-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Accepted: 01/03/2024] [Indexed: 04/19/2024]
Abstract
OBJECTIVE Rathke cleft cysts (RCCs) are benign, epithelial-lined sellar lesions that arise from remnants of the craniopharyngeal duct. Due to their rarity in the pediatric population, data are limited regarding the natural history and optimal management of growing or symptomatic RCCs. We present our institutional experience with the surgical management of RCCs. METHODS We performed a retrospective study of consecutive RCC patients ≤ 18 years old treated surgically at our institution between 2006 and 2022. RESULTS Overall, 567 patients with a diagnosis of pituitary mass or cyst were identified. Of these, 31 had a histopathological diagnosis of RCC, 58% female and 42% male. The mean age was 13.2 ± 4.2 years. Presenting symptoms included headache (58%), visual changes (32%), and endocrinopathies or growth delay (26%); 13% were identified incidentally and subsequently demonstrated growth on serial imaging. Six percent presented with symptomatic intralesional hemorrhage. Surgical approach was transsphenoidal for 90% of patients and orbitozygomatic for 10%. Preoperative headaches resolved in 61% of patients and preoperative visual deficits improvement in 55% after surgery. New pituitary axis deficits were seen in 9.7% of patients. Only two complications occurred from a first-time surgery: one cerebrospinal fluid leak requiring lumbar drain placement, and one case of epistaxis requiring cauterization. No patients experienced new visual or neurological deficits. Patients were followed postoperatively with serial imaging at a mean follow-up was 62.9 ± 58.4 months. Recurrence requiring reoperation occurred in 32% of patients. Five-year progression-free survival was 47.9%. Except for one patient with multiple neurological deficits from a concurrent tectal glioma, all patients had a modified Rankin Scale score of 0 or 1 (good outcome) at last follow-up. CONCLUSION Due to their secretory epithelium, pediatric RCCs may demonstrate rapid growth and can cause symptoms due to local mass effect. Surgical management of symptomatic or growing pediatric RCCs via cyst fenestration or partial resection of the cyst wall can be performed safely, with good neurologic outcomes. There is a nontrivial risk of endocrinologic injury, and long-term follow up is needed due to high recurrence rates.

Abstract
There is no standard of care for management of Rathke cleft cysts (RCCs), and protocol for spontaneous rupture or residual capsule fragments is not well documented.Our case involves a Caucasian man in his 80s who presented with muscle weakness, fatigue, bitemporal hemianopia and pain. Further examination demonstrated decreased thyroid and cortisol levels. MRI revealed a 1.6×1.5×1.3 cm sellar homogenous mass with extension into the suprasellar cistern. While the size of the cyst was rather large, a decision was made to follow conservatively with serial MRI. At 3 years, the mass had spontaneously regressed. The patient was asymptomatic without imaging evidence of RCC recurrence at 4-year follow-up.Classic indications for surgical intervention in suprasellar cysts were subtle in our patient and his advanced age made us take a conservative approach. Current data are lacking regarding management of RCCs presenting with endocrine dysfunction. Our case suggests that RCCs presenting with endocrine dysfunction may be managed conservatively with serial imaging-based monitoring.

Abstract
Rathke's cleft cyst (RCC) apoplexy is an uncommon lesion attributed to abnormal vascular supply to the fragile RCC epithelial wall. It is rare in children and very difficult to diagnose without pathologic confirmation. Here, we report an 8-year-old boy who presented with headache and visual deficit. MRI and CT showed a cystic mass in the sellar region. He underwent endoscopic endonasal surgery, and the cystic mass was resected completely via a trans-sphenoidal approach. The lesion was confirmed as RCC apoplexy by intraoperative observation and histopathological examination. Headache was completely relieved and the visual field deficit improved remarkably after the operation. The authors recommend surgical management for pediatric RCC apoplexy patients who present with severe neuro-ophthalmic signs or deterioration of consciousness, although there are at present no standardized management guidelines for pediatric RCC apoplexy.

Long-term outcomes and potential predictive recurrence factors after endonasal endoscopic surgical treatment of symptomatic Rathke's cleft cysts. Neurosurg Rev 2024; 47:85.

Abstract
Although patients with symptomatic Rathke's cleft cysts (RCCs) receive surgical treatment, recurrence sometimes occurs after surgery. However, the mechanism underlying recurrence remains unclear. We evaluated the outcomes of RCC decompression over a long-term follow-up period. We retrospectively reviewed the medical records of 35 patients with symptomatic RCC who underwent endonasal endoscopic surgery (EES) at our institution between 2008 and 2023. Patients' characteristics, intraoperative findings, and postoperative follow-up outcomes were evaluated. A univariate regression model was used to identify the predictors of recurrence. The median patient age was 48.0 years, and 74.2% of the patients were female. The mean follow-up duration was 94.7 ± 47.6 months. Cyst content recurrence was observed in 15 patients (42.8%). Five patients (14.2%) with symptomatic recurrence underwent reoperation. Postoperative vision improved in all 23 patients (100%); headaches improved in 20 patients (90.9%). A new hormonal deficit occurred in two patients (5.7%). Complications included intraoperative cerebrospinal fluid (CSF) leak in 10 patients (28.5%), postoperative CSF leak in two patients (5.7%), permanent diabetes insipidus in two patients (5.7%), and postoperative infection in three patients (8.5%). Univariate analyses revealed that the position of the anterior pituitary lobe (p = 0.019) and preoperative visual disturbances (p = 0.008) significantly affected recurrence after surgery. Although EES was efficient, the recurrence rate was relatively high over a long-term period. The anterior pituitary lobe position and preoperative visual disturbances were significantly associated with recurrence. The anterior-inferior position can predict a high risk of recurrence before surgery.

Abstract
BACKGROUND AND PURPOSE Cystic pituitary adenomas and cystic craniopharyngiomas may mimic Rathke cleft cysts when there is no solid enhancing component on magnetic resonance imaging (MRI). This study aims to investigate the efficiency of MRI findings in differentiating Rathke cleft cysts from pure cystic pituitary adenoma and pure cystic craniopharyngioma. MATERIALS AND METHODS 109 patients were included in this study (56 Rathke cleft cysts, 38 pituitary adenomas, and 15 craniopharyngiomas). Preoperative magnetic resonance images were evaluated using 9 imaging findings. These findings include intralesional fluid-fluid level, intralesional septations, midline /off-midline location, suprasellar extension, an intracystic nodule, a hypointense rim on T2-weighted images, ≥ 2 mm thickness of contrast-enhancing wall, T1 hyperintensity and T2 hypointensity. p < 0.01 was considered statistically significant. RESULTS There was a statistically significant difference among groups for these 9 findings. Intracystic nodule and T2 hypointensity were the most specific MRI findings in differentiating Rathke cleft cyst from the others (98.1% and 100%, respectively). Intralesional septation and thick contrast-enhancing wall were the most sensitive MRI findings ruling out Rathke cleft cysts with 100% sensitivity. CONCLUSION Rathke cleft cysts can be distinguished from pure cystic adenoma and craniopharyngioma with the presence of an intracystic nodule, T2 hypointensity, the absence of the thick contrast-enhancing wall, and absence of intralesional septations.

Abstract
Recurrence of Rathke's cleft cysts (RCC) following surgery is not uncommon. We present a 33-year-old male patient with chronic headache and visual disturbances whose MRI showed mostly cystic, suprasellar mass with peripheral enhancement. Endoscopic extended transsphenoidal approach and tumor resection was performed and RCC was pathologically confirmed postoperatively. Early recurrence was first suspected at 3 months following surgery, and his serial MRIs showed a recurred mass without associated clinical symptoms. Upon further histopathological study, extensive squamous metaplasia and high Ki-67 were seen. Also, in this study, we discuss important factors associated with cyst recurrence following surgery.

Abstract
PURPOSE Although Rathke cleft cysts (RCC) are benign lesions of the sellar region, recurrence is frequent after surgical treatment. Nuclear translocation of ß-catenin (NTßC), a key effector of the wnt-signaling pathway that is responsible for cell renewal, has been shown to act as a proto-oncogene and is considered to be a potential risk factor for increased recurrence in RCC. In this study, we analyzed a surgically treated cohort into patients with and without NTßC expression in order to identify clinical and imaging differences and further evaluate the risk of recurrence. METHODS Patients with resection of RCC between 04/2001 and 11/2020 were included. Histological specimens were immunohistochemically stained for ß-catenin. Study endpoints were time to cyst recurrence (TTR) and functional outcome. Functional outcome included ophthalmological and endocrinological data. Furthermore, MRI data were assessed. RESULTS Seventy-three patients (median age 42.3 years) with RCC underwent mainly transsphenoidal cyst resection (95.9%), 4.1% via transcranial approach. Immunohistochemical staining for ß-catenin was feasible in 61/73 (83.6%) patients, with nuclear translocation detected in 13/61 cases (21.3%). Patients with and without NTßC were equally likely to present with endocrine dysfunction before surgery (p = 0.49). Postoperative new hypopituitarism occurred in 14/73 (19.2%) patients. Preoperative visual impairment was equal in both groups (p = 0.52). Vision improved in 8/21 (33.3%) patients and visual field deficits in 22/34 (64.7%) after surgery. There was no difference in visual and perimetric outcome between patients with and without NTßC (p = 0.45 and p = 0.23, respectively). On preoperative MRI, cyst volume (9.9 vs. 8.2 cm3; p = 0.4) and evidence of hemorrhage (30.8% vs. 35.4%; p = 0.99) were equal and postoperative cyst volume decreased significantly in both groups (0.7 vs. 0.5 cm3; p < 0.0001 each). Cyst progression occurred in 13/73 (17.8%) patients after 39.3 ± 60.3 months. Cyst drainage with partial removal of the cyst wall resulted in improved recurrence-free survival without increasing the risk of complications compared with cyst fenestration alone. Patients with postoperative diabetes insipidus had an increased risk for recurrence according to multivariate analysis (p = 0.005). NTßC was evident in 4/15 patients (26.7%) and was not associated with a higher risk for recurrence (p = 0.67). CONCLUSION Transnasal transsphenoidal cyst drainage with partial removal of the cyst wall reduces the risk of recurrence without increasing the risk of complications compared with fenestration of the cyst alone. Patients with postoperative diabetes insipidus seem to have an increased risk for recurrence. In contrast, NTßC was not associated with a higher risk of recurrence and did not provide stratification for clinically distinct patients.

Abstract
PURPOSE Large Rathke's cleft cysts (LRCCs) and cystic craniopharyngiomas (CCPs) arise from the same embryological origin and may have similar MR presentations. However, the two tumors have different management strategies and outcomes. This study was designed to evaluate the clinical and imaging findings of LRCCs and CCPs, aiming to evaluate their pretreatment diagnosis and outcomes. METHODS We retrospectively enrolled 20 patients with LRCCs and 25 patients with CCPs. Both tumors had a maximal diameter of more than 20 mm. We evaluated the patients' clinical and MR imaging findings, including symptoms, management strategies, outcomes, anatomic growth patterns and signal changes. RESULTS The age of onset for LRCCs versus CCPs was 49.0 ± 16.8 versus 34.2 ± 22.2 years (p = .022); the following outcomes were observed for LRCCs versus CCPs: (1) postoperative diabetes insipidus: 6/20 (30%) versus 17/25 (68%) (p = .006); and (2) posttreatment recurrence: 2/20 (10%) versus 10/25 (40%) (p = .025). The following MR findings were observed for LRCCs versus CCPs: (1) solid component: 7/20 (35%) versus 21/25 (84%) (p = .001); (2) thick cyst wall: 2/20 (10%) versus 12/25 (48%) (p = .009); (3) intracystic septation: 1/20 (5%) versus 8/25 (32%) (p = .030); (4) snowman shape: 18/20 (90%) versus 1/25 (4%) (p < .001); (5) off-midline extension: 0/0 (0%) versus 10/25 (40%) (p = .001); and (6) oblique angle of the sagittal long axis of the tumor: 89.9° versus 107.1° (p = .001). CONCLUSIONS LRCCs can be differentiated from CCPs based on their clinical and imaging findings, especially their specific anatomical growth patterns. We suggest using the pretreatment diagnosis to select the appropriate surgical approach and thus improve the clinical outcome.

Abstract
BACKGROUND Rathke cleft cysts (RCCs) are common benign skull-base lesions arising from embryologic remnants of Rathke pouch. Though frequently asymptomatic, RCCs can become symptomatic because of compression of adjacent neural structures. Transcranial and neuroendoscopic surgical treatments have been described for symptomatic RCCs, but recurrence rates remain as high as 30%. Bioabsorbable steroid-eluting (BASE) stents significantly decrease adhesions and recurrent ostia obstruction after endoscopic sinus surgery. We sought to use BASE stents to aid marsupialization of symptomatic RCCs. OBJECTIVE To present long-term results of our initial experience with endoscopic-endonasal fenestration and placement of BASE stents for RCCs. METHODS Patients undergoing neuroendoscopic transsphenoidal fenestration of RCCs with BASE stent placement were identified and their medical records retrospectively reviewed. RESULTS Four patients underwent neuroendoscopic transsphenoidal fenestration and BASE stent placement from March 2016 to April 2018 for symptomatic RCCs. After the cyst contents were evacuated, a BASE stent was deployed in the cyst fenestration to prevent cyst wall regrowth or closure and facilitate marsupialization to the sphenoid sinus. No perioperative complications were encountered, and all patients reported symptom resolution by 2 weeks postoperatively. Postoperative endoscopic evaluation demonstrated epithelization of the cyst wall opening and patent marsupialization into the sphenoid sinus in all cases. After a mean follow-up of 56 ± 12 months, all patients remained asymptomatic with baseline visual function and no radiographic evidence of recurrence. CONCLUSION Bioabsorbable steroid-eluting stent placement is a safe, facile, viable augmentation of neuroendoscopic technique for symptomatic RCCs with the potential to reduce long-term recurrence rates.

Abstract
OBJECTIVES We have previously shown that pituitary cysts may affect growth hormone secretion. This study sought to determine cyst evolution during growth hormone treatment in children. METHODS Forty-nine patients with short stature, a pituitary cyst, and at least two brain MRI scans were included. The percent of the pituitary gland occupied by the cyst (POGO) was calculated, and a cyst with a POGO of ≤15% was considered small, while a POGO >15% was considered large. RESULTS Thirty-five cysts were small, and 14 were large. Five of the 35 small cysts grew into large cysts, while 6 of the 14 large cysts shrunk into small cysts. Of 4 cysts that fluctuated between large and small, 3 presented as large and 1 as small. Small cysts experienced greater change in cyst volume (CV) (mean=61.5%) than large cysts (mean=-0.4%). However, large cysts had a greater net change in CV (mean=44.2 mm3) than small cysts (mean=21.0 mm3). Older patients had significantly larger mean pituitary volume than younger patients (435.4 mm3 vs. 317.9 mm3) and significantly larger mean CV than younger patients (77.4 mm3 vs. 45.2 mm3), but there was no significant difference in POGO between groups. CONCLUSIONS Pituitary cyst size can vary greatly over time. Determination of POGO over time is a useful marker for determining the possibility of a pathologic effect on pituitary function since it factors both cyst and gland volume. Large cysts should be monitored closely, given their extreme, erratic behavior.

Abstract
Backgroud Recurrence of Rathke's cleft cyst (RCC) is not uncommon after surgery, and the associated factors and incidence of relapse deserve a systematic summary. Methods This study was conducted in accordance with Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. The Pubmed, Embase, Cochrane, and Web of Science databases were searched until September 12, 2022. Studies with significant results of recurrent factors or specific incidences of RCC recurrence and mean/median follow-up time were included. Based on a protocol of a 2-year interval grouping, included studies were categorized into four groups with follow-up periods <24 months, 24-48 months, 48-72 months, and ≥72 months, respectively. Quality assessment was performed using the NOS score. Pooled estimations were computed by using a random-effects model in the STATA "metaprop" command. Publication bias was assessed visually through a funnel plot and statistically through Egger's linear regression test and Begg's correlation test. Results A total of 44 studies were included containing 2,539 cases. Squamous metaplasia was the most commonly reported factor, followed by the extent of cyst removal. The other factors were reported individually. The pooled overall incidences of RCC recurrence after surgery in four groups of the follow-up period were 7.4% (95%CI = 4.1-11.3%) in <24 months, 13.1% (95%CI = 9.7-17.0%) in 24-48 months, 13.7% (95%CI = 7.7-21.0%) in 48-72 months, and 33.8% (95%CI = 19.6-49.6%) in ≥72 months. The pooled symptomatic incidences were 2.3% (95%CI = 0.4-5.1%) in <24 months, 5.6% (95%CI = 3.6-7.9%) in 24-48 months, 5.9% (95%CI = 2.4-10.6%) in 48-72 months, and 14.1% (95%CI = 6.0-24.5%) in ≥72 months. A dramatic increase in recurrent incidence was observed when the follow-up period was more than 72 months in both overall and symptomatic recurrence. A similar trend of recurrence was found in subgroup analyses stratified by publication year, cohort size, and cyst resection strategy. Conclusion This study systematically reviewed recurrent factors and described the profile of trends in RCC recurrent incidence after surgery with a follow-up time based on a protocol of a 2-year interval, finding a dramatic increase in recurrent rates with a follow-up period of more than 72 months. This encouraged us to put forward a recommendation of at least a 6-year follow-up after surgery for patients with RCC.

Abstract
The aim of the present study is to retrospectively analyze the surgical outcomes and complications of microscopic and endoscopic transsphenoidal surgery in the management of Rathke cleft cysts (RCCs) at a single institution. A total of 38 patients were enrolled in this study. All patients were diagnosed with RCCs, which were confirmed histopathologically. Endocrine function, radiological, and clinical outcomes were evaluated following surgery. This cohort study consisted of 16 male and 22 female patients. The median age was 48 years (range, 21-72). The median clinical follow-up duration was 57 months (range, 3-187). Twenty-five patients underwent microscopic transsphenoidal surgery and 13 patients underwent endoscopic surgery. The cysts were located within the intrasellar area in 18 (47.4%) patients, and extended to the suprasellar area in 20 (52.6%) patients. The radiological characteristics were similar in the microscope and endoscope groups, except mass volume (1.40 vs 0.65 mm3; P = .003) and peripheral rim enhancement (P = .036). After surgery, 30 (78.9%) of the 38 patients had no residual cysts. There was no significant difference in outcomes between both groups (76.0% vs 84.6%; P = .689). Four (10.5%) patients experienced cyst recurrence in only the microscope group. Twenty-four of the 25 patients who presented with headache showed improvement after surgery. Four patients with visual field defects recovered after surgery. Among the 8 patients with hormonal deficiencies, hormone levels normalized in 5 patients, did not change in 2 patients and worsened in 1 patient. New hormonal deficiencies occurred in 3 patients. Microscopic or endoscopic transsphenoidal surgery for RCCs is a safe and effective treatment option. Complete aspiration of the cyst contents with wide fenestration and wall biopsy, regardless of the surgical approach used, is usually a sufficient treatment for RCCs.

Abstract
OBJECTIVE Rathke cleft cysts (RCCs) are benign lesions originating from remnants of the Rathke pouch. RCCs have been classified into the intrasellar-based or purely suprasellar types. This research aims to study the optimal treatment nuances and evaluate the surgical outcomes of this distinct type of RCCs. METHODS This study retrospectively reviewed 36 patients with purely suprasellar RCCs who were treated by expanded endonasal endoscopic approach (EEA) from September 2018 to January 2021. The demographic data, presenting symptoms, endocrine status, imaging findings, operative details, and surgical outcomes were analyzed. RESULTS According to the relationship with pituitary stalk, the suprasellar RCCs can be divided into 2 different growth patterns: intrastalk cyst (ISC, 52.8%) and extrastalk cyst (ESC, 47.2%). Preoperative endocrine dysfunctions occurred more in patients with ISC than ESC (P = 0.007), which are characterized by hypoadrenalism (P = 0.004) and hypogonadism (P = 0.008). Operation exerted different impacts on endocrine functions between ISC and ESC (P = 0.012). When identifying by single hypothalamic-pituitary axis, 4 patients with normal endocrine function developed a new hormonal deficit, 14 patients with preoperative endocrine dysfunctions benefited from our expanded EEA surgical treatment, and 3 of them completely recovered from the endocrinopathy after surgery. The postoperative endocrinopathy was positively associated with the numbers of preoperative abnormal endocrinal axes. Thirty-four (94.4%) patients had achieved gross total resection. Pituitary stalk was intactly preserved in 23 of 36 patients (63.9%), partly preserved in 10 patients, and not preserved in 3 patients. CONCLUSIONS Purely suprasellar RCCs are a distinct type of RCCs, which originate from the pituitary stalk above the diaphragmatic sellae, and the treatment strategy via expanded EEA is a rational choice. Classification based on growth patterns would be beneficial to reduce endocrine disorders after surgery.

Abstract
Background: Rathke’s cleft cysts (RCC) arise from the pars intermedia because of incomplete regression of the embryologic Rathke pouch. A subset of RCC becomes symptomatic causing headaches, visual and endocrinological disturbances such that surgical intervention is indicated. Several points in surgical management remain controversial including operative strategy (simple fenestration (SF) vs complete cyst wall resection (CWR)) as well as reconstructive techniques. Methods: A retrospective analysis was conducted of pathologically confirmed RCC operated on by endoscopic endonasal approach from 2006 to 2019. Pre-operative symptoms, imaging characteristics, operative strategy, symptom response, complications and recurrences were recorded. Results: Thirty-nine patients were identified. Thirty-three underwent SF and six underwent CWR. Worsening pituitary function was significantly increased with CWR (50%) compared to SF (3%) (p = 0.008). All patients underwent “closed” reconstruction with a post-operative CSF leak rate of 5% (3% SF vs 16% CWR, p = 0.287). Six (15%) recurrences necessitating surgery were reported. Recurrence rates stratified by surgical technique (18% SF vs 0% CWR, p = 0.564) were not found to be significantly different. Conclusions: The current series illustrates variability in the surgical management of RCCs. SF with closed reconstruction is a reasonable operative strategy for most symptomatic RCCs cases while CWR can be reserved for selected cases.

Abstract
Nonneoplastic epithelial cysts involving the central nervous system are diverse and are predominantly developmental in origin. This study represents a surgical series describing the histopathological features of 507 such epithelial cysts with clinical and imaging correlation. Age at surgery ranged from 7 months to 72 years (mean: 33 years) affecting 246 male and 261 female patients. Colloid cyst was the most frequently resected cyst, followed by epidermoid cyst, arachnoid cyst, Rathke cleft cyst, dermoid cyst, neurenteric cyst, Tarlov cyst, and choroid plexus cyst. Diagnosis was based on the location of the cysts and the nature of the lining epithelium. Rathke cleft cyst showed the highest propensity for squamous metaplasia, significant inflammation, and xanthogranulomatous reaction. Ulceration of lining epithelium and calcification were most frequent in dermoid cyst. Radiopathological concordance was maximal for colloid cyst, followed by epidermoid and arachnoid cysts. Epidermoid and dermoid cysts exhibited the highest propensity for local tumor progression, followed by Rathke cleft cyst.

Abstract
OBJECTIVE Rathke's cleft cysts (RCCs) are sellar collections from an incompletely regressed Rathke's pouch. Common symptoms of RCCs can include headaches, visual loss, and endocrinopathy. Surgery is required in some cases of symptomatic or growing RCCs. Recurrence after surgery is common (range 10%-40%). Stereotactic radiosurgery (SRS) has been used in an attempt to control growth and symptoms, but outcomes are not well known. The authors sought to study the outcomes of RCCs following Gamma Knife surgery for both salvage and initial treatment. METHODS The outcomes of 25 patients with RCCs who underwent SRS between 2001 and 2020 were reviewed. Four patients received initial SRS and 21 were treated with salvage SRS. Diagnosis was based on imaging or histopathology. Cyst control was defined as stability or regression of the cyst. Kaplan-Meier analysis was used to determine time to recurrence and determine potential factors for recurrence. RESULTS The respective median clinical follow-up and margin dose were 6.5 years and 12 Gy. Overall control was achieved in 19 (76%) of 25 patients, and 4 recurrences required further intervention. The average time to recurrence was 35.6 months in those RCCs that recurred. Visual recovery occurred in 14 (93.3%) of 15 patients and no new post-SRS visual deficits occurred. The presence of a pretreatment visual deficit was often an indicator of RCC regrowth. All 3 patients with pretreatment hyperprolactinemia experienced resolution after SRS. New endocrinopathy related to SRS was noted in 5 (20%) of 25 patients, all of which were thyroid and/or cortisol axis related. Upfront SRS was used in 4 patients. No new endocrinopathies or visual deficits developed after upfront SRS, and the 1 patient with a pretreatment visual deficit recovered. One of the 4 patients with upfront SRS experienced a recurrence after 7.5 years. CONCLUSIONS SRS produced effective recovery of visual deficits and carries a low risk for new visual deficits. Cyst control was achieved in approximately three-fourths of the patients. Following SRS, patients without pretreatment visual deficits are less likely to have RCC regrowth. Endocrinopathy can occur after SRS, similar to other sellar mass lesions. Initial SRS shows the potential for long-term cyst control, with improvement of symptoms and a low risk for complications.

Abstract
Purpose We aimed to assess factors influencing the occurrence of delayed hyponatremia after transsphenoidal surgery in patients with Rathke's cleft cysts (RCCs). Methods We retrospectively collected the clinical data of patients who underwent transsphenoidal surgery for RCCs from January 2014 to January 2022. Univariate and multivariate analyses were used to determine the factors influencing the occurrence of postoperative delayed hyponatremia. Results Of the 78 microscopic transsphenoidal surgery recipients with RCCs, 15 experienced postoperative delayed hyponatremia. There were 35 men and 43 women, and mean age was 43.75 ± 14.95 years. The clinical manifestations of RCCs were headache (62 cases, 79.5%), visual dysfunction (35 cases, 44.9%), endocrine dysfunction symptoms (12 cases, 15.4%). After transsphenoidal surgery, 93.5% (58/62) had improvements in headache, and 97.1% (34/35) had improved or resolved compressive visual symptoms. Delayed hyponatremia occurred on average on day 6.46 and lasted on average for 4.40 days. Logistic regression analysis showed that the independent influencing factor of delayed hyponatremia after transsphenoidal surgery in patients with RCCs was postoperative diaphragma sellae height. Conclusion Postoperative diaphragma sellae height was identified as an independent influencing factor for delayed hyponatremia after transsphenoidal surgery in patients with RCCs.

Identifying risk factors for postoperative diabetes insipidus in more than 2500 patients undergoing transsphenoidal surgery: a single-institution experience. J Neurosurg 2022; 137:647-657.

Abstract
OBJECTIVE Diabetes insipidus (DI) following transsphenoidal surgery can adversely impact quality of life and be difficult to manage. This study sought to characterize pre- and perioperative risk factors that may predispose patients to DI after pituitary surgery. METHODS A retrospective review of patients treated at a single institution from 2007 to 2019 was conducted. DI was defined as postoperative sodium > 145 mEq/L and urine output > 300 ml/hr and/or postoperative desmopressin (ddAVP) use. DI was further characterized as transient or permanent. Uni- and multivariate analyses were performed to determine variables associated with postoperative DI. RESULTS The authors identified 2529 patients who underwent transsphenoidal surgery at their institution. Overall, DI was observed in 270 (10.7%) of the 2529 patients, with 114 (4.5%) having permanent DI and 156 (6.2%) with transient symptoms. By pathology type, DI occurred in 31 (46.3%) of 67 craniopharyngiomas, 10 (14.3%) of 70 apoplexies, 46 (14.3%) of 322 Rathke's cleft cysts, 77 (7.7%) of 1004 nonfunctioning pituitary adenomas (NFPAs), and 62 (7.6%) of 811 functioning pituitary adenomas (FPAs). Final lesion pathology significantly affected DI rates (p < 0.001). Multivariate analysis across pathologies showed that younger age (odds ratio [OR] 0.97, p < 0.001), intraoperative CSF encounter (OR 2.74, p < 0.001), craniopharyngioma diagnosis (OR 8.22, p = 0.007), and postoperative hyponatremia (OR 1.50, p = 0.049) increased the risk of DI. Because surgery for each pathology created specific risk factors for DI, the analysis was then limited to the 1815 pituitary adenomas (PAs) in the series, comprising 1004 NFPAs and 811 FPAs. For PAs, younger age (PA: OR 0.97, p < 0.001; NFPA: OR 0.97, p < 0.001; FPA: OR 0.97, p = 0.028) and intraoperative CSF encounter (PA: OR 2.99, p < 0.001; NFPA: OR 2.93, p < 0.001; FPA: OR 3.06, p < 0.001) increased DI rates in multivariate analysis. Among all PAs, patients with DI experienced peak sodium levels later than those without DI (postoperative day 11 vs 2). Increasing tumor diameter increased the risk of DI in FPAs (OR 1.52, p = 0.008), but not in NFPAs (p = 0.564). CONCLUSIONS In more than 2500 patients treated at a single institution, intraoperative CSF encounter, craniopharyngioma diagnosis, and young age all increased the risk of postoperative DI. Patients with postoperative hyponatremia exhibited higher rates of DI, suggesting possible bi- or triphasic patterns to DI. Greater vigilance should be maintained in patients meeting these criteria following transsphenoidal surgery to ensure early recognition and treatment of DI.

Abstract
BACKGROUND Xanthomatous lesions of the pituitary have been linked to ruptured or hemorrhagic Rathke’s cleft cysts. Most cases are reported to resolve following radical resection. When recurrence does occur, there is no established treatment regimen. High-dose glucocorticoids have been reported to be beneficial in several published cases; however, their effects are often not sustained once therapy is discontinued. OBSERVATIONS The authors report the case of an adolescent male who developed recurrent xanthogranulomatous hypophysitis associated with a Rathke’s cleft cyst despite two surgical interventions. He was treated with a short course of dexamethasone followed by a maintenance course of celecoxib and mycophenolate mofetil. This regimen proved to be safe and well-tolerated, and it successfully prevented another recurrence of his xanthogranulomatous hypophysitis. LESSONS This case demonstrates a novel nonsurgical approach to the management of recurrent xanthogranulomatous hypophysitis. It suggests a potential application of a combined corticosteroid-sparing immunosuppressive and anti-inflammatory regimen in other cases of refractory xanthogranulomatous hypophysitis.

Abstract
BACKGROUND Purely suprasellar and some complex intra-suprasellar Rathke cleft cysts (RCCs) are commonly treated via extended endonasal endoscopic approach or traditional transcranial approach. The feasibility of the trans-eyebrow supraorbital keyhole approach (TSKA) for RCCs was evaluated in this retrospective study. METHODS A cohort of 16 patients (11 females and 5 males) with RCC was surgically treated via TSKA between January 2013 and November 2021. The medical data and follow-up results were analyzed. RESULTS Eight patients had a purely suprasellar RCC, and 8 patients had an intra-suprasellar RCC with most of pituitary gland occupying the sellar floor. The mean maximal size of the cysts was 15.4 (range 7-29) mm. Postoperatively, complete cyst drainage was achieved in 15 (93.7%) patients. Preoperative headache, visual dysfunction, and hypopituitarism improved in 12 (100.0%), 3 (75.0%) and 3 (75.0%) patients, respectively, and hyperprolactinemia normalized in all patients. Except 2 (12.5%) cases of transient diabetes insipidus (TDI), no other complications were observed. During the mean follow-up period of 41.0 (range 4-102) months, 1 (6.3%) radiological recurrence was found. CONCLUSIONS For the treatment of purely suprasellar and some intra-suprasellar RCCs with most of the pituitary occupying the sellar floor, the endoscopic TSKA has the advantage of the minimal invasiveness, excellent visualization of the intrasellar compartment, no additional damage to the underlying pituitary gland, and no risk of CSF leakage. TDI or DI is relative commonly found in treatment of these RCCs. During surgery, care should be taken to avoid damage to the surrounding structures, including the pituitary stalk.

Abstract
Rathke's cleft cysts (RCCs) are sellar or suprasellar cystic lesions arising from the remnants of the embryological Rathke's pouch. When symptomatic, RCCs are usually treated surgically via marsupialization. Free mucosal graft (FMG) repair has shown promise in decreasing recurrence versus marsupialization alone. The authors present a case report with operative video of a patient with visual and endocrinological symptoms with a RCC treated with FMG following marsupialization. A search of the PubMed database from July 1997 through April 2022 was conducted using the terms 'Rathke's cleft cyst', 'Rathke's cleft cyst management', 'Rathke's cleft cyst repair', 'mucosal graft', 'mucosal coupling', 'transsphenoidal', and 'endoscopic endonasal'. Clinical and pathological aspects of the case presented were compared with information obtained from literature review. A 25-year-old female presented with a six-year history of amenorrhea, one-year history of anemia, headaches, and progressive visual loss. Imaging revealed an RCC. The patient underwent surgical treatment via an endoscopic endonasal approach. Marsupialization was achieved with placement of an FMG to help prevent restenosis. Post-operative examination revealed that the patient's OD vision returned to normal, although her OS vision was only slightly improved. Our review of the English literature resulted in 35 full-length articles that were published between 1997 and 2022. The literature suggests that FMG prevents scar formation by allowing for adequate epithelialization, thus decreasing the recurrence rate and being well tolerated by patients. Our findings support the utility of the FMG as a superior surgical treatment option for RCC management.

Abstract
OBJECTIVE To establish the effect of endoscopic endonasal surgery (EES) on quality-of-life (QoL) in symptomatic Rathke cleft cyst (RCC). METHODS Analysis of 38 patients with RCC treated by EES, with regular overall (ASBQ-35) and sinonasal-specific (SNOT-22) QoL assessment during the first postoperative year. A systematic literature review of large case series was performed with pooled analysis. RESULTS In our series, mean age was 53.6 years with a female predominance (73.7%). Larger cysts were seen in males (p < 0.01), those with hypogonadism (p = 0.04), and visual dysfunction (p = 0.04). Complete normalisation of vision was seen in 83.3%. Persistence of visual dysfunction postoperatively was associated with diabetes (p = 0.005), hypertension (p = 0.02), suprasellar only location (p = 0.001), and monocular field cut (p = 0.02). Surgery did not significantly effect hormonal function. Sinonasal QoL transiently worsened after surgery, resolving within 3 weeks. A parallel transient worsening of overall QoL normalised by 6 weeks, and remained at preoperative baseline thereafter. These results were comparable to the literature, where 76.4% demonstrated improvement of vision and 13.1% had recurrence after treatment. There was no significant difference in outcomes between EES and microscopic approaches. CONCLUSIONS We report longitudinal QoL outcomes in RCC for the first time. Vision commonly improves with surgery, but endocrinopathy is likely to persist. Microvascular risk-factors may compromise visual improvement. Surgery causes a transient worsening of sinonasal symptoms that resolves within 3-6 weeks, but patients may not experience significant improvement in QoL within the first postoperative year.

Abstract
Symptomatic Rathke’s cleft cysts (RCCs) can be treated by surgical procedures, usually through an endonasal transsphenoidal corridor using either a microscope or an endoscope. We report a large suprasellar extended RCC causing obstructive hydrocephalus, which was efficiently managed by a novel surgical route named “reverse” trans-sellar approach using transventricular neuroendoscopy. A 48-year-old woman complained of persistent headache and a tendency to fall that had begun 6 months previously. The images obtained from MRI scan showed intra- and supra-sellar cystic masses occupying the third ventricle with obstruction of the foramina of Monro and the aqueduct of Sylvius. The cystic wall showed a slight enhancement, and the cystic contents showed iso-signal intensity on T1-and T2-weighted images. Instead of trans-nasal trans-sellar surgery, we decided to operate using a conventional transventricular endoscope. A thin cystic capsule, which blocked the foramina of Monro and the aqueduct of Sylvius, was fenestrated and removed and a third ventriculostomy was performed. The defect in the infundibulum between sellar and suprasellar cysts was widened and used as a corridor to drain cystic contents (reverse trans-sellar route). The final pathological finding revealed an RCC with focal metaplasia. We efficiently managed a large RCC by transventricular neuroendoscopic surgery with cyst fenestration and third ventriculostomy and simultaneously drained the sellar contents using a novel surgical route. Reverse trans-sellar neuroendoscopic surgery is a relevant treatment option for selective patients with large suprasellar extensions of RCCs.

Abstract
OBJECTIVE We sought to elucidate the long-term surgical outcomes and incidence of recurrence and reoperation of endoscopic endonasal cyst fenestration for Rathke cleft cyst (RCC). METHODS A retrospective review of the chart and operation record of RCC surgical cases between January 2008 and August 2021 at our institution was conducted. Patient characteristics, intraoperative findings, and postoperative follow-up outcomes were evaluated. RESULTS A total of 27 patients were analyzed, with a median postoperative follow-up period of 52 months (range, 1-150 months). Preoperative symptoms were visual dysfunction (59%), headache (41%), and pituitary dysfunction (22%). Endoscopic cyst fenestration was performed in all patients. Ten (37%) patients had intraoperative cerebrospinal fluid leakage. Among them, the only patient in whom sellar floor reconstruction was not performed experienced a repair operation due to postoperative cerebrospinal fluid leakage. No patients experienced postoperative hypopituitarism. Preoperative headache, visual dysfunction, and pituitary hormone disorder improved in 73%, 75%, and 67% of patients, respectively. Although postoperative cyst regrowth was observed in 8 patients (30%), no patient experienced worsening or novel symptoms and none required reoperation. CONCLUSIONS Patients with a symptomatic RCC can be effectively treated with endoscopic endonasal cyst fenestration. Reversal of the presenting symptoms resulted, including headache, visual dysfunction, and pituitary hormone dysfunction, in the majority of patients. In our series, appropriate reconstruction of the sellar floor reduced the risk of postoperative cerebrospinal fluid leakage without impacting cyst regrowth. This simple technique appears to effectively disrupt cyst progression in most cases, even after a relatively long-term follow-up period.

Abstract
PURPOSE Half of the surgically proven Rathke's cleft cysts (RCCs) can be preoperatively misdiagnosed as cystic pituitary adenoma (CPA). We aimed to evaluate the usefulness of contrast-enhanced (CE) 3D T2 fluid-attenuated inversion-recovery (3D T2-FLAIR) imaging for differentiating between CPA and RCC. METHODS This retrospective study included six patients with RCC (all pathologically confirmed) and six patients with CPA (five pathologically confirmed, one clinically diagnosed). The 12 patients underwent pre- and post-contrast T1-weighted (T1W)- and 3D T2-FLAIR imaging at 3T. Based on the degree of enhancement of the lesion wall, two radiologists independently scored the images using a 3-point grading system. Interobserver agreement was calculated by using the κ coefficient. The statistical significance of grading differences was analyzed with the Mann-Whitney U-test. Another neuroradiologist first interpreted conventional MR images (1st session), and then the reader read images to which the 3D T2-FLAIR images had been added (2nd session). Sensitivity, specificity, and accuracy of the reader's interpretation were calculated. RESULTS Interobserver agreement for post-contrast T1W- and 3D T2-FLAIR images was excellent (κ = 1.000 and 0.885, respectively). Although the mean enhancement grade on post-contrast T1W images of RCCs and CPAs was not significantly different, on post-contrast 3D T2-FLAIR images it was significantly higher for RCCs and CPAs (P < 0.05). Three CPAs (50%) showed remarkable, donut-like enhancement along the inner margin of the cyst on CE-3D T2-FLAIR images; this was not the case on CE-T1W images. The sensitivity, specificity, and accuracy of the 2nd session were 1.00, 0.83, and 0.92, respectively, which were improved compared to the 1st session (1.00, 0.50, and 0.75, respectively). CONCLUSION CE-3D FLAIR imaging is useful for discriminating CPAs and RCCs.

Abstract
The sellar and parasellar region is complex, with a unique meningeal, neural, vascular, and bony anatomy. Understanding the imaging anatomy is critical for accurate imaging interpretation. resonance (MR) imaging is the primary modality for pituitary imaging, whereas computed tomography may be used when MR imaging is contraindicated, and provides complementary bony anatomic information. This article reviews embryology and anatomy of the sellar and parasellar region. Imaging appearances of pituitary adenomas, Rathke cleft cysts, meningiomas, craniopharyngiomas, arachnoid cysts, vascular disorders, infectious abnormalities, and pituitary apoplexy are discussed and illustrated.

Abstract
Objective: Rathke cleft cysts (RCC) are benign sellar lesions, and endoscopic endonasal surgery (EES) for symptomatic RCC is becoming increasingly popular, but total resection or partial resection (TR or PR) of the cyst wall is still inconclusive. The aim of this study was to review the complications and clinical prognoses associated with total and partial resection of the cyst wall by EES. Methods: We retrospectively analyzed a series of 72 patients with symptomatic RCC treated by EES from -January 2011 to June 2019 at Shenzhen University First Affiliated Hospital. For these 72 cases, 30 were treated with TR and 42 were treated with PR. Intra- and post-operative complications and clinical prognosis were investigated. Results: All 72 patients underwent a pure EES. In the TR group, 10 patients (33.3%) had intraoperative cerebrospinal fluid leakage (CSF leak), three patients (10%) had postoperative CSF leak, eight patients (26.7%) had postoperative diabetes insipidus (DI), eight patients (26.7%) had postoperative electrolyte disturbance, and 12 patients (40%) had temporary hypopituitarism postoperatively. While in the PR group, three patients (7.1%) had intraoperative CSF leak, two patients (4.8%) had postoperative DI, three patients (7.1%) had postoperative electrolyte disturbance, four patients (9.5%) had temporary hypopituitarism postoperatively, and no cases experienced postoperative CSF leak. The intra- and post-operative complications were significantly higher in TR group then PR group (P IntraoperativeCSFleak = 0.004, P Post−operativeCSFleak =0.036, P TransientDI = 0.008, P Temporaryhypopituitarism = 0.002, P Permanenthypopituitarism = 0.036, P Electrolytedisturbance = 0.023). No significant differences in post-operative improvement and recurrence. Conclusions: EES is a safe and effective approach for the treatment of symptomatic RCC. Complete sucking out the cyst contents and partial resection of the cyst wall may be sufficient for treatment, and total resection of the cyst wall is associated with a higher incidence of complications.

Spinal dural arteriovenous fistula rupture after Rathke's cleft cyst endoscopic resection: Case report and literature review. Surg Neurol Int 2021; 12:455. [PMID: 34621570 PMCID: PMC8492439 DOI: 10.25259/sni_654_2021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 08/11/2021] [Indexed: 11/11/2022] Open
Abstract
Background: Spinal dural arteriovenous fistula (SDAVF) is the most frequent vascular malformation of the spine and accounts for approximately 70% of all vascular spinal malformations. In rare cases, SDAVF rupture and subsequent subarachnoid hemorrhage or intramedullary hematoma may occur. The aim of this article is to present a fatal case of SDAVF rupture after a Rathke’s cleft cyst (RCC) endoscopic resection. Case Description: An 80-year-old female was referred to our hospital with a clinical presentation of bilateral reduction in visual acuity, bitemporal hemianopsia, and sellar magnetic resonance imaging (MRI) highly suggestive of RCC. After the first endonasal endoscopic surgery, the cyst was partially removed and vision improved. No signs of cerebrospinal fluid (CSF) leak were observed. After 1 year, the patient returned because of RCC recurrence and decreased visual acuity. In the second procedure, the lesion was totally resected and CSF leak was observed. A nasoseptal flap was rotated to cover the skull base defect. The patient developed subtle paraparesis followed by paraplegia on the 4th postoperative day. The dorsal spine MRI revealed a T3-T4 intramedullary hematoma. A dorsal laminectomy was performed and a SDAVF was observed. During microsurgery, at the right T3 nerve root level, an arteriovenous shunting point was identified, coagulated, and divided. The intramedullary hematoma was evacuated. The patient developed neurogenic and septic shock and died. Conclusion: Venous hypertension, venous wall fragility, and venous thrombosis seem to be the main factors involved in SDAVF rupture. In this particular case, reduction of the extravascular pressure and sudden variation in the pressure gradient caused by sustained CSF leak, also appeared to play an important role in SDAVF rupture. It may represent one more complication related to radical resection of RCC.

Abstract
Primary tumors of the pituitary gland are the second most common histologic category of primary central nervous system tumors across all age groups and are the most common in adolescents to young adults, despite originating from a diminutive endocrine gland that is often described as "about the size of a pea." The vast majority of these represent primary tumors of the adenohypophysis, specifically pituitary adenomas, which can be either functional or silent with regard to hormone hypersecretion. According to the fourth edition of the World Health Organization classification of endocrine tumors, published in 2017, cellular lineage and immunohistochemical stains for pituitary hormones and/or transcription factors help with making the correct pathologic diagnosis. From a radiologic standpoint, microadenomas pose challenges for accurate detection and avoiding false-negative or false-positive results, while macroadenomas pose challenges from local mass effect on surrounding structures. Pituitary carcinoma and pituitary blastoma also arise from the adenohypophysis and are characterized by metastatic disease and infantile presentation, respectively. While primary tumors of the adenohypophysis are common, a second category comprising primary tumors of the Rathke pouch (ie, craniopharyngioma) are uncommon, and a third category comprising primary tumors of the neurohypophysis (eg, pituicytoma) are rare. The authors review all three categories of pituitary tumors, with emphasis on radiologic-pathologic correlation, including the typical neuroimaging, histologic, and molecular features that may point toward a specific diagnosis.

Abstract
PURPOSE Pituitary abscesses (PAs) are a rare clinical entity which may arise from normal pituitary tissue or underlying lesions within the gland. Rathke's cleft cysts (RCCs) are not commonly associated with the development of PA. METHODS Retrospective chart review of three patients with PAs within RCCs at a single university center and review of the literature. RESULTS Three cases are reported. The first case presented with fever and headache and a history of prior surgery due to RCC and a recent respiratory tract infection. The second case had a history of recent skin infections and presented with sudden onset headache and hypopituitarism. In the third case, chronic visual field impairment prompted an ophthalmologic evaluation resulting in a diagnosis of an adenoma and an infected RCC. In all three cases, an endoscopic endonasal approach was performed to drain infected tissue and allowed microbiological identification of gram-positive cocci, followed by treatment with antibiotics for at least three weeks. Cases in the literature are scarce and the diagnosis is usually made intraoperatively due to non-specific manifestations and imaging. PAs arising from underlying pituitary lesions are less common than primary PAs. Differential diagnosis should include pituitary apoplexy, hypophysitis and other cystic lesions. CONCLUSION PAs occurring in RCCs are infrequent. Clinical manifestations are commonly subacute, without septic symptoms. Imaging is usually non-specific. Preoperative diagnosis is infrequent and a broad differential diagnosis should be considered. Empirical antimicrobial therapy should be initiated and adjusted after obtaining cultures to reduce the rate of recurrence and improve clinical outcomes.

Abstract
Many reviews have summarised the pathology and management of the parasellar region in adult patients, although an analysis of these aspects in the transition years, from puberty onset to the age of peak bone mass, has been lacking. A comprehensive search of English-language original articles, published from 2000 to 2020, was conducted in the MEDLINE database (December 2019 to March 2020). We selected all studies regarding epidemiology, diagnosis and management of the following parasellar lesions: germinoma, craniopharyngioma, Langerhans cell histiocytosis, optic glioma, hypothalamic hamartoma, tuber cinereum hamartoma, cranial chordoma, Rathke cleft cyst, hypophysitis and hypothalamitis during the transition age from childhood to adulthood. In the present review, we provide an overview of the principal parasellar lesions occurring in the transition age. Symptoms are usually a result of the mass effect of the lesions on nearby structures, as well as anterior pituitary deficits. Diabetes insipidus occurs frequently in these patients. In this age group, pubertal developmental disorders may be more evident compared to other stages of life. Parasellar lesions in the transition age mostly include neoplastic lesions such as germinomas, hamartomas, optic gliomas, craniopharyngiomas Langerhans cell histiocytosis and chordomas, and rarely inflammatory lesions (hypophysitis, hypothalamitis). There are limited data on the management of parasellar lesions in the transition age. Endocrine evaluation is crucial for identifying conditions that require hormonal treatment so that they can be treated early to improve the quality of life of the individual patient in this complex age range. The clinical approach to parasellar lesions involves a multidisciplinary effort.

Abstract
OBJECTIVE To evaluate the response of incidentally discovered pituitary cysts to growth hormone (GH) treatment. METHODS A retrospective chart review was performed of children with pituitary cysts on magnetic resonance imaging (MRI) over a 5-year period. Records and images were reviewed, and the results were analyzed using descriptive statistics. Children with pituitary cysts who received GH treatment were compared with those without. RESULTS We identified 109 children with pituitary cysts, 24 were treated with GH therapy. The average age was 8.5 ± 5.1 years. Children whose initial MRI scan was to evaluate growth hormone deficiency were more commonly male and non-Hispanic White compared with those with scans for other indications (male, 18 of 24 vs 35 of 85, P = .003; White, 23 of 24 vs 58 of 85, P = .004). Among patients who received GH treatment, 12 had follow-up MRI. Six had no change in cyst size and 6 had a decrease in cyst size. We observed no difference in the likelihood of cyst growth between those who received GH and those who did not (0 of 12 cysts with GH vs 1 of 15 cysts without GH showed growth at follow-up). No patient had neurologic deficits attributable to the pituitary cyst at any time. CONCLUSION In a single-institution, retrospective study, we find no evidence of growth in pituitary cysts in response to GH therapy.

Abstract
BACKGROUND Diagnosing the well-known concomitant Rathke's cleft cyst (RCC) and differentiating it from other sellar lesions are difficult because RCC is and other sellar lesions are closely related and represent a continuum from simple RCCs to more complex lesions. The purpose of this study is to better understand the adeno- and neurohypophysis adjacent to the par intermedia remnants and their role in the origin of the coexistence of these two distinct tumor neoplasias; to assess the incidence in different age groups; to categorize the pathohistological subtype, which can be incorporated in predictive/prognostic models; and finally, to evaluate the current evidence on collision tumors of the sellar embryonic remnant tract in terms of their biological behavior and pathology. METHODS Utilizing the PubMed database, data were collected from 1920 to 2019. Information about demographics, clinical characteristics, and age was summarized and analyzed by using univariable and multivariable models. The same cell type was observed regardless of whether the tumor was only one type or mixed types, and their histologic patterns were assessed. RESULTS The incidence rates were similar among patients stratified into three age subgroups: 40-49 years (24.57%), 50-59 years (19.54%), and older than 60 years (22.98%). We found that various types of sellar lesions, namely, squamous metaplasia (SM) + goblet cells (GC) (HR 46.326), foamy macrophages (FM) (HR 39.625), epithelial cells and multinucleated giant cells or cholesterin (EM) (HR 13.195), a cavernous portion of the right internal carotid artery (CP-ICA) (HR 9.427), epithelial cells with ciliated cuboidal (EC-CC) (HR 8.456), were independently associated with RCC pathological status. These divergent AUCs (0.848 for Hypo as RCC, 0.981 for RCC co PA, 0.926 for CD and CP co RCC) and subtypes of PA (HR 4.415, HR 2.286), Hypo (HR 3.310), CD and CP (HR 2.467), EC and DC and PG and SGR (HR 1.068), coexisting with the risk of a comorbid RCC lesion, may reflect the etiologic heterogeneity of coderivation and the different effects of some risk factors on tumor subtypes. Our analyses suggested that the greatest accuracy was observed for the pituitary adenoma subtype, with an AUC of 0.981 (95% confidence interval [CI]: 0.959-1.005), while the poorest accuracy was observed for aneurysms, with an AUC of 0.531 (95% CI: 0.104-0.958). We separately analyzed and confirmed the above results. Sensitivity analysis revealed no evidence of systematic bias due to missing data. CONCLUSION This study showed that the histopathological changes in patients with sellar embryonic remnant-associated collision tumors showed highly consistent epithelial cell replacement (renewal) (ciliated columnar epithelium to ciliated squamous epithelium to squamous epithelium) or accumulation, and the RCC cyst wall was similar in structure to the tracheobronchial airway epithelium, with progenitor cell characteristics. The collision accuracy between RCC and other tumors (PAs, craniopharyngioma, chordoma, etc.) is different; these characteristics constitute the theoretical basis for the postmigration development of the pharyngeal bursa.

Abstract
BACKGROUNDRathke cleft cyst (RCC) has a recurrence rate of 10% to 22%, and preventing recurrence is challenging. For patients who experience persistent recurrence of RCC, placement of steroid-eluting bioabsorbable intrasellar stents has been rarely described. However, recurrences are often delayed, suggesting that dissolvable stents may not be successful long-term. The release of steroids in close proximity to the pituitary gland may also unintentionally influence the hypothalamic-adrenal-pituitary axis.OBSERVATIONSThe authors present a case of a 66-year-old woman with a persistently recurrent RCC who underwent drainage of her cyst with placement of a nonabsorbable intrasellar stent in the form of a tympanostomy tube. After repeat transsphenoidal drainage of her cyst, a tympanostomy T-tube was placed to stent open the dural aperture. Postoperatively, the patient’s condition showed improvement clinically and radiographically.LESSONSPlacement of an intrasellar stent for recurrent RCC has rarely been described. Steroid-eluting bioabsorbable stents may dissolve before RCC recurrence and may have an unintentional effect on the hypothalamic-pituitary-adrenal axis. The authors present the first case of nonabsorbable stent placement in the form of a tympanostomy tube for recurrence of RCC. Additional studies and longer follow-up are necessary to evaluate the long-term efficacy of both absorbable and nonabsorbable stent placement.

Abstract
Rathke's cleft cyst (RCC) is a common incidental tumor in the hypothalamic-pituitary region. Some reports have shown that the clinical symptoms and endocrine functions of symptomatic RCCs are temporarily improved by glucocorticoid administration. However, it is still unknown whether glucocorticoid treatment is effective for symptomatic RCCs according to long-term observations. In this study, we describe the long-term clinical outcomes of two cases of glucocorticoid-treated biopsy-proven secondary hypophysitis caused by RCCs. We summarize the symptoms, imaging findings, and endocrine evaluations of two symptomatic RCC patients with concomitant hypophysitis before and after prednisolone treatment. In both evaluated cases, visual impairments and altered endocrine parameters were present due to chiasm and stalk compression; these outcomes improved after shrinkage of RCCs in response to prednisolone administration, and partial recovery of anterior pituitary hormone secretion was observed. However, in both cases, the deficits in anterior pituitary hormone secretion recurred, possibly due to persistent inflammatory infiltration in the RCCs and pituitary glands. After relapse of hypophysitis, anterior hormone secretion did not fully recover. In our cases of secondary hypophysitis caused by RCCs, prednisolone administration had an early effect of cyst shrinkage, followed by partial improvements in clinical symptoms and pituitary functions. However, long-term observation showed that prednisolone treatment did not contribute to complete improvement in anterior pituitary hormone dysfunction.

Abstract
The transcription factor ISL1 is expressed in pituitary gland stem cells and the thyrotrope and gonadotrope lineages. Pituitary-specific Isl1 deletion causes hypopituitarism with increased stem cell apoptosis, reduced differentiation of thyrotropes and gonadotropes, and reduced body size. Conditional Isl1 deletion causes development of multiple Rathke's cleft-like cysts, with 100% penetrance. Foxa1 and Foxj1 are abnormally expressed in the pituitary gland and associated with a ciliogenic gene-expression program in the cysts. We confirmed expression of FOXA1, FOXJ1, and stem cell markers in human Rathke's cleft cyst tissue, but not craniopharyngiomas, which suggests these transcription factors are useful, pathological markers for diagnosis of Rathke's cleft cysts. These studies support a model whereby expression of ISL1 in pituitary progenitors drives differentiation into thyrotropes and gonadotropes and without it, activation of FOXA1 and FOXJ1 permits development of an oral epithelial cell fate with mucinous cysts. This pituitary-specific Isl1 mouse knockout sheds light on the etiology of Rathke's cleft cysts and the role of ISL1 in normal pituitary development.

Abstract
The diagnosis and management of mass lesions in the sellar and parasellar areas remain challenging. When approaching patients with possible sellar or hypothalamic masses, it is important not only to focus on imaging but also detect possible pituitary hormone deficits or excess, in order to establish an appropriate diagnosis and initiate treatment. The imaging modalities used to characterize hypothalamic and pituitary lesions have significantly evolved over the course of the past several years. Computed tomography (CT) and CT angiography play a major role in detecting various sellar lesions, especially in patients who have contraindications to magnetic resonance imaging (MRI) and can also yield important information for surgical planning. However, MRI has become the gold standard for the detection and characterization of hypothalamic and pituitary tumors, infections, cystic, or vascular lesions. Indeed, the imaging characteristics of hypothalamic and sellar lesions can help narrow down the differential diagnosis preoperatively. In addition, MRI can help establish the relationship of mass lesions to surrounding structures. A pituitary MRI examination should be obtained if there is concern for mass effect (including visual loss, ophthalmoplegia, headache) or if there is clinical suspicion and laboratory evidence of either hypopituitarism or pituitary hormone excess. The information obtained from MRI images also provides us with assistance in planning surgery. Using intraoperative MRI can be very helpful in assessing the adequacy of tumor resection. In addition, MRI images yield reliable data that allow for noninvasive monitoring of patients postoperatively.

Abstract
OBJECTIVE Rathke's cleft cyst (RCC) is a benign cystic lesion with a relatively high incidence of local recurrence that occasionally requires repeat surgery. To prevent recurrence, simple cyst fenestration and drainage of the cyst contents to the sphenoid sinus is recommended, but it occasionally recurs. The authors postulated that obstruction of fenestration is a main cause of recurrence, and they developed a method, named the "mucosa coupling method (MC method)," that maintains persistent drainage. In this method, the RCC epithelium and the mucosa of the sphenoid sinus are connected, which promotes re-epithelialization between the two epithelia, maintaining persistent drainage. The outcome of this method was compared with that of conventional cyst fenestration. METHODS In a consecutive series of 40 patients with RCC, the surgical strategy was changed during the study period: from December 2009 to September 2014 (the conventional period), 24 patients were scheduled to be treated using the conventional fenestration method, whereas from September 2014 to September 2017 (the MC period), 16 patients were scheduled to be treated using the MC method. However, because of an intraoperative CSF leak, the fenestration was closed during surgery in 3 patients in the conventional period and 2 in the MC period; therefore, these 5 patients were excluded from the analysis. Twenty-one patients treated with the conventional fenestration method (conventional group) and 14 patients treated with the MC method (MC group) were analyzed. All patients regularly underwent MRI after surgery to detect reaccumulation of cyst contents. The rate of reaccumulation with and without reoperation, visual outcomes, endocrinological outcomes, and postoperative complications were compared between these two groups. RESULTS The median follow-up period in all 35 patients was 48.0 months (range 1-96 months), 54.0 months (range 1-96 months) in the conventional group and 35.5 months (range 12-51 months) in the MC group. No reaccumulation was detected on MRI in the 14 patients in the MC group, whereas it was noted in 9 (42.9%) of 21 patients in the conventional group, and 2 of these 9 patients required repeat surgery. There were no significant differences in visual and endocrinological outcomes and complications between these two groups. CONCLUSIONS The MC method for RCC is effective for preventing obstruction of cyst fenestration, which contributes to preventing cyst reaccumulation. Furthermore, this method is equivalent to the conventional fenestration method in terms of visual and endocrinological outcomes and the complication rate.

Abstract
BACKGROUND Nonneoplastic cysts of the pituitary are common incidental findings; however, best management remains controversial as they are often asymptomatic but eventually may cause symptoms. The aims of this study are to describe the course of conservative and surgical approaches, to assess timing and results of surgery, and to identify predictors for growth. METHODS This retrospective study reviewed medical records from the Swiss Pituitary registry. Fifty patients (68% females; median 44 years old) fulfilled the criteria for inclusion. Three cohorts were defined: a conservative group (n = 28), a group who initially needed surgery (n = 18), and a group who had surgery during follow-up (n = 4). Transsphenoidal cyst evacuation was used in 95%; 68% had intraoperative MRI. All patients had standardized neuroradiological, endocrinological, and ophthalmological follow-up (mean 44 (7-151) months). RESULTS Conservative follow-up of 30 (6-120) months showed cyst growth in 16% (4%/year) and spontaneous shrinkage in 19% (8%/year). Cyst-volumes changed - 0.95 to 1.45 cm3 per year. The probability of needing surgery was 5% per year. Larger cysts (> 1.4 cm3) and T1-hypo-/T2-hyper cyst contents were associated with higher probability for growth. Postoperatively, no remnant was seen in 82% during a follow-up of 53 months. Visual field deficiencies improved in 83%. Hypopituitarism recovered in up to 88%. But for a smaller complication rate, the outcome was not influenced by the use of the intraoperative MRI. CONCLUSIONS Asymptomatic nonneoplastic pituitary cysts may be monitored; many lesions may shrink with time. Larger or T1-hypo-/T2-hyper cysts have higher growth rates. If indicated, surgery for nonneoplastic sellar cysts is a safe and efficient.

Abstract
Purpose: The aim of this study was to investigate the diagnostic value of machine-learning models with radiomic features and clinical features in preoperative differentiation of common lesions located in the anterior skull base. Methods: A total of 235 patients diagnosed with pituitary adenoma, meningioma, craniopharyngioma, or Rathke cleft cyst were enrolled in the current study. The discrimination was divided into three groups: pituitary adenoma vs. craniopharyngioma, meningioma vs. craniopharyngioma, and pituitary adenoma vs. Rathke cleft cyst. In each group, five selection methods were adopted to select suitable features for the classifier, and nine machine-learning classifiers were employed to build discriminative models. The diagnostic performance of each combination was evaluated with area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, and specificity calculated for both the training group and the testing group. Results: In each group, several classifiers combined with suitable selection methods represented feasible diagnostic performance with AUC of more than 0.80. Moreover, the combination of least absolute shrinkage and selection operator as the feature-selection method and linear discriminant analysis as the classification algorithm represented the best comprehensive discriminative ability. Conclusion: Radiomics-based machine learning could potentially serve as a novel method to assist in discriminating common lesions in the anterior skull base prior to operation.

Abstract
BACKGROUND Rathke cleft cysts (RCCs) are benign sellar and suprasellar lesions commonly presenting as asymptomatic incidental findings. Rarely, RCCs hemorrhage and mimic pituitary apoplexy on presentation. OBJECTIVE To review a series of hemorrhagic RCCs for physicians encountering this rare presentation. METHODS A database review of >1700 transsphenoidal pituitary operations was performed at the USC Pituitary Center to identify patients with pathologically confirmed RCCs presenting with acute symptoms and evidence of hemorrhage at the time of surgery. Surgical treatment involved transsphenoidal RCC fenestration and drainage. Clinical, endocrine, and imaging outcomes were reviewed. RESULTS A total of 119 RCCs were identified, and 6 (5.0%) presented with hemorrhage mimicking pituitary apoplexy. Presenting symptoms included acute onset headaches (5/6), vision loss (2/6), and oculomotor nerve palsy (n = 1). Endocrine disturbances at presentation included pre-existing amenorrhea in all female patients (3/3), hypothyroidism (n = 2), panhypopituitarism (n = 2), and one with profound hyponatremia (Na 116 meq/L). All patients underwent endonasal transsphenoidal fenestration and drainage with no major complications. Over mean follow-up of 38.4 mo, 2/2 patients with vision loss reported improvement, and 2/5 patients with headaches reported improvement. Although all women resumed menses, patients with preoperative hypopituitarism did not experience pituitary axis improvement. Follow-up magnetic resonance imaging showed no instances of RCC recurrence with a mean imaging follow-up of 38.6 mo. CONCLUSION RCCs occasionally present with hemorrhage and clinical symptoms that may be confused with apoplexy. Outcomes following hemorrhagic RCC treatment are excellent when treated at tertiary pituitary centers. Although hyperprolactinemia often improves following surgery, other pituitary axis deficits typically do not.

Abstract
BACKGROUND Rathke cleft cyst (RCC) can cause acute symptoms mimicking pituitary adenoma (PA) apoplexy. We evaluated the clinicoradiologic features for distinguishing RCC from PA apoplexy. METHODS We retrospectively evaluated 22 patients with RCC and 24 patients with PA with apoplexy-like symptoms who underwent surgery via a transsphenoidal approach between November 1999 and December 2016. We compared the clinical data and magnetic resonance (MR) images between the 2 groups. RESULTS The RCC group was younger and had smaller tumors compared with the PA group (P = 0.02 and 0.001, respectively). The incidences of visual deficits and cranial nerve palsy were lower in the RCCs than in the PAs (P ≤ 0.02 for all). MR images showed more frequent intracystic nodules in the RCCs (P < 0.001), whereas nodular enhancement and lateral deviation of the pituitary stalk were more commonly seen in the PAs (P ≤ 0.003 for both). However, the presence of endocrine dysfunction or decreased consciousness, and the recurrence ratio, were not significantly different between the groups (P ≥ 0.48 for all). In the multivariable logistic regression analysis, patients without nodular enhancement had a 15.84-fold greater risk of RCC than did those with nodular enhancement (P = 0.031). The probability of RCC decreased 0.59-fold with each 1-cm3 increase in tumor volume. CONCLUSIONS RCC with apoplexy-like symptoms has different clinicoradiologic features compared with PA apoplexy. Patients with RCC present with milder ocular symptoms and smaller tumor volumes compared with those with PA apoplexy. The absence of nodular enhancement on MR images could suggest RCC.

Limb R, King J. Relationship between Recurrence Rates of Rathke's Cleft Cysts and Surgical Approaches to Sellar Reconstruction. J Neurol Surg B Skull Base 2020; 82:e105-e111. [PMID: 34306924 DOI: 10.1055/s-0040-1701223] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Accepted: 12/02/2019] [Indexed: 10/25/2022] Open
Abstract
Objective The main purpose of this article is to address the question of whether reconstructing the sellar floor following Rathke's cleft cyst excision results in increased rates of recurrence. Methods and Design A retrospective case series was compiled from medical records and radiological investigations at a single institution over a time period spanning 25 years. Episodes of cyst recurrence were determined from magnetic resonance imaging scans and outpatient encounters. Details regarding surgical procedure and techniques were obtained from operation notes. Perioperative morbidity was also recorded. Results Twenty-three adult patients were treated surgically for a Rathke's cleft cyst at the study institution between 1992 and 2017. The overall cyst recurrence rate was 48%, with 39% of all patients requiring redo surgery within the timeframe of the study. The mean time to redo surgery for recurrence was 4 years. Cyst recurrence rates were 57% postmicroscopic procedures, and 26% postendoscopic procedures ( p = 0.148). In the nonreconstructed group, the recurrence rate was 17%, and in the reconstructed group the recurrence rate was 41% ( p = 0.3792). Complications arising after nonreconstructive procedures were delayed cerebrospinal fluid rhinorrhea, pneumocephaly, and multiple episodes of meningitis. All these patients required return to theater for secondary reconstruction of the pituitary fossa floor. Conclusion The results of this small study suggest that reconstruction of the sellar floor, and microscopic rather than endoscopic techniques, may be associated with a higher rate of Rathke's cleft cyst recurrence. However, these trends did not reach statistical significance. Patients undergoing nonreconstructive procedures may be more prone to certain postoperative complications.

Stereotactic Radiation as Salvage Therapy for Recurrent Rathke Cleft Cysts. Neurosurgery 2020; 87:754-760. [DOI: 10.1093/neuros/nyz523] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Accepted: 10/01/2019] [Indexed: 12/27/2022] Open
Abstract
Abstract
BACKGROUND
Rathke cleft cysts (RCCs) are sellar-based cystic lesions that are often found incidentally but occasionally become symptomatic with significant visual and/or endocrine deficits. The standard of treatment is surgery, but rare cases of multiply recurrent RCCs can be refractory to surgical drainage, leading to significant morbidity.
OBJECTIVE
To demonstrate the safety and feasibility of fractionated stereotactic radiotherapy (SRT) as salvage therapy in multiply recurrent RCCs refractory to surgical drainage.
METHODS
An IRB-approved retrospective review at a single institution was conducted to identify and describe patients with multiply recurrent RCCs refractory to surgical drainage who underwent SRT.
RESULTS
From 1994 to 2015, 6 patients (5 female) who underwent SRT for recurrent RCCs were identified. A total of 4 presented with visual deficits, and 2 presented with endocrine dysfunction and severe headaches prior to their initial drainage. All patients had initial postoperative improvement but then developed multiple, symptomatic recurrences. Median number of surgical drainage procedures prior to radiotherapy was 3. A total of 3 patients underwent LINAC-based SRT, and 3 had proton-based SRT. Treatment doses were 45 Gy over 25 fractions (n = 5) and 50.4 Gy over 28 fractions (n = 1). Median follow-up after radiation therapy was 69 mo (range 24-154 mo). In the follow-up period, stabilization of the RCC was achieved, although 2 patients required additional drainage procedures. Only 1 patient developed new hypothyroidism and hypoadrenalism after SRT.
CONCLUSION
In rare cases of multiply recurrent RCCs refractory to repeat surgical drainage, stereotactic fractionated radiation therapy is a safe and effective salvage therapy.
