Long-term outcomes and potential predictive recurrence factors after endonasal endoscopic surgical treatment of symptomatic Rathke's cleft cysts. Neurosurg Rev 2024; 47:85. [PMID: 38366128 DOI: 10.1007/s10143-024-02322-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Revised: 01/22/2024] [Accepted: 02/12/2024] [Indexed: 02/18/2024]
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.

Qian A, Zhou J, Zhang X, Yu J, Wang X. Incidence and factors associated with the recurrence of Rathke's cleft cyst after surgery: A systematic review and meta-analysis. Front Surg 2023; 9:1065316. [PMID: 36684167 PMCID: PMC9849585 DOI: 10.3389/fsurg.2022.1065316] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Accepted: 12/05/2022] [Indexed: 01/06/2023] Open
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
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
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.

Rathke's cleft cysts following transsphenoidal surgery: long-term outcomes and development of an optimal follow-up strategy. Acta Neurochir (Wien) 2020; 162:853-861. [PMID: 31982988 PMCID: PMC7066099 DOI: 10.1007/s00701-020-04237-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 01/18/2020] [Indexed: 01/09/2023]
Abstract
BACKGROUND In patients with symptomatic Rathke's cleft cyst, transsphenoidal surgery is highly effective at preventing further visual loss and usually allows for some recovery of vision. However, cyst recurrence and the need for re-operation are well recognized. To this end, the aim of this study was to investigate patterns of recurrence and long-term outcomes and to use this information to develop an optimal follow-up strategy. METHOD A prospectively maintained database was searched over a 10-year period between 1 January 2008 and the 1 January 2018 to identify all adults that underwent transsphenoidal surgery with a new diagnosis of Rathke's cleft cyst. A retrospective case note review was performed for each patient to extract data on their presentation, investigation, treatment, and outcome. RESULTS In all, 61 eligible patients were identified. The median follow-up was 34 months (range 2-112 months). In the 22 patients with pre-operative visual loss, the outcomes at 6 months were as follows: normal vision (2/22; 9.1%), improved but not normal (7/22; 31.8%), stable (12/22; 54.5%), worse but not blind (1/22; 4.5%), and blind (0/22; 0%). The overall rate of regrowth and re-operation in our study was 19.7 and 11.5%, respectively. The only factor that was significantly associated with recurrence was the presence of residual cystic disease on the post-operative MRI (p < 0.001). CONCLUSIONS We propose a follow-up strategy that stratifies patients at "low risk" if there is no residual cyst, with increasing interval scans, or "high risk" if there is residual cyst, with annual visual assessment and scans.

Abstract
BACKGROUND Limited data exist pertaining to outcomes following surgery for recurrent Rathke's cleft cysts (RCC). OBJECTIVE To determine treatment outcomes in patients undergoing reoperation for recurrent or residual RCCs. METHODS A retrospective analysis of 112 consecutive RCC operations in 109 patients between 1995 and 2017 was conducted. RESULTS Eighteen patients underwent 21 RCC reoperations with a mean follow-up of 58 mo. Patient symptoms prior to reoperation included headaches (14, 66.7%) and vision loss (12, 57.1%). Thirteen of 18 patients (72.2%) required hormone supplementation prior to reoperation including 5 with diabetes insipidus (DI). Mean RCC diameter was 16 mm and 76% had suprasellar extension. Compared to index RCC cases, intraoperative cerebrospinal fluid leak repair was more common in reoperation cases (15/21, 71% vs 43/91, 47%, P = .05). There was 1 carotid artery injury without neurological sequelae, and 2 postoperative cerebrospinal fluid (CSF) leaks (9.5%). Rates of transient hyponatremia (3/10, 30% vs 4/91, 4.4%, P = .04) and transient DI (5/10, 50% vs 17/91, 18.7%, P = .04) were higher in the reoperation vs index group. Improved headaches and vision were reported in 4/12 (33%) and 8/12 (61.5%) of RCC reoperation patients, respectively. Two patients developed new permanent DI. A higher proportion of reoperation patients had RCC squamous metaplasia (24% vs 5.4%, P = .02) or wall inflammation (42.9% vs 2.2%, P < .001) on pathological examination. CONCLUSION Reoperation for RCCs is generally safe at tertiary pituitary centers and often results in improved vision. Hypopituitarism is less likely to improve following reoperation for recurrent RCCs. Several histopathological features may help characterize "atypical RCCs" with a higher likelihood of recurrence/progression.

Neurosurg Rev 2019; 43:957-966. [PMID: 31041618 DOI: 10.1007/s10143-019-01107-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 03/25/2019] [Accepted: 04/15/2019] [Indexed: 12/29/2022]
Abstract
Rathke's cleft cysts (RCCs) are benign growths of the embryological Rathke's pouch. Surgical decompression provides effective symptomatic relief in most cases; however, the effect of gross total resection (GTR) of the cyst wall on recurrence, as well as pituitary function, is unclear. The aim of this meta-analysis was to pool the current literature and ascertain the recurrence control afforded by GTR of the cyst wall compared with subtotal resection (STR). Searches of seven electronic databases from inception to January 2019 were conducted following PRISMA guidelines, resulting in 476 articles to be screened. Outcomes were analyzed using meta-analysis of proportions. A total of 10 retrospective cohort studies satisfied selection criteria, describing 655 surgically managed RCC cases, with 254 (39%) and 401 (61%) achieving GTR and STR of the cyst wall, respectively. GTR was associated with significantly reduced overall RCC recurrence by fixed-effects (FE) modeling (RR, 0.66; 95% CI, 0.45-0.96), but not by random effects (RE) modeling (RR, 0.75; 95% CI, 0.51-1.12). Based on both models, GTR was associated with significantly reduced symptomatic recurrence (RE model, RR, 0.37, 95% CI, 0.14-0.95) and significantly increased postoperative diabetes insipidus (RE model, RR, 2.60; 95% CI, 1.34-5.03). There was insufficient data to evaluate other pituitary axes in this context. The current evidence indicates that GTR of the RCC cyst wall has the potential to affect the incidence of overall and symptomatic RCC recurrences, as well as drive postoperative DI incidence. However, expectations of clinical and pragmatic benefit following cyst wall resection should be titrated carefully against the potential for postoperative and pituitary morbidities which currently remain poorly defined. Greater granularity is required to understand all factors that can influence recurrence and quality of life when evaluating resection of RCC.

Abstract
OBJECTIVE Rathke's cleft cysts (RCCs) are benign epithelial lesions of the sellar region typically treated via a transsphenoidal approach with cyst fenestration and drainage. At present, there is limited evidence to guide patient selection for operative treatment. Furthermore, there is minimal literature describing factors contributing to cyst recurrence. METHODS The authors conducted a retrospective analysis of 109 consecutive cases of pathology-confirmed RCCs treated via a transsphenoidal approach at a single center from 1995 to 2016. The majority of cases (86.2%) involved cyst fenestration, drainage, and partial wall resection. Long-term outcomes were analyzed. RESULTS A total of 109 surgeries in 100 patients were included, with a mean follow-up duration of 67 months (range 3-220 months). The mean patient age was 44.6 years (range 12-82 years), and 73% were women. The mean maximal cyst diameter was 14.7 mm. Eighty-eight cases (80.7%) were primary operations, and 21 (19.3%) were reoperations. Intraoperative CSF leak repair was performed in 53% of cases and was more common in reoperation cases (71% vs 48%, p < 0.001). There were no new neurological deficits or perioperative deaths. Two patients (1.8%) developed postoperative CSF leaks. Transient diabetes insipidus (DI) developed in 24 cases (22%) and permanent DI developed in 6 (5.5%). Seven cases (6.4%) developed delayed postoperative hyponatremia. Of the 66 patients with preoperative headache, 27 (44.3%) of 61 reported postoperative improvement and 31 (50.8%) reported no change. Of 31 patients with preoperative vision loss, 13 (48.1%) reported subjective improvement and 12 (44.4%) reported unchanged vision. Initial postoperative MRI showed a residual cyst in 25% of cases and no evidence of RCC in 75% of cases. Imaging revealed evidence of RCC recurrence or progression in 29 cases (26.6%), with an average latency of 28.8 months. Of these, only 10 (9.2% of the total 109 cases) were symptomatic and underwent reoperation. CONCLUSIONS Transsphenoidal fenestration and drainage of RCCs is a safe and effective intervention for symptomatic lesions, with many patients experiencing improvement of headaches and vision. RCCs show an appreciable (although usually asymptomatic) recurrence rate, thereby mandating serial follow-up. Despite this, full RCC excision is typically not recommended due to risk of hypopituitarism, DI, and CSF leaks.

Abstract
BACKGROUND Rathke's cleft cysts (RCC) are lesions that arise from Rathke's pouch. Though frequently incidental, resulting symptoms in a minority of cases are indicators for surgical resection, which may prove beneficial. OBJECTIVE To characterize a cohort of surgically-resected RCC cases at Oregon Health & Science University; tabulate associated hormonal imbalances and symptoms, possible symptom reversal with surgery, determine recurrence risk; identify predictors of recurrence and headache improvement. METHOD Electronic records of all RCC resected cases (from 2006-2016; 11 years) were retrospectively reviewed. Patients had been evaluated by one neuroendocrinologist using a uniform protocol. RESULTS A pathological RCC diagnosis was established in 73 of 814 (9%) surgical pituitary cases. The RCC cohort was 77% (n = 56/73) female, mean age was 39.5 ± 14.9 years at first surgery, and at presentation headache was reported in 88% and visual defects/diplopia in 18% of patients. Initial RCC maximum diameter was 1.3 ± 0.7 cm. The most frequent hormonal deficit was cortisol; 24% of patients had a new adrenal insufficiency (AI) diagnosis, however, 36% also had AI at 3 months post-operatively. Mean follow up was 4.0 ± 4.5 years. Two-thirds of patients (41/62) had headache improvement 3 months post-operatively. Post-operative imaging revealed no residual cyst in 58% (38/65). In those patients with no residual RCC, 29% had recurrence and 71% had long lasting cure. From the 42% (27/65) of patients with residual cyst on post-operative imaging; 59% (16/27) remained stable, 26% (7/27) progressed and 15% (4/27) regressed. CONCLUSION Symptomatic RCC present mostly in women, with a high proportion reporting headaches. Prevalence of AI at diagnosis is high. Surgery may not achieve adrenal axis recovery, but renders a high percentage of headache improvement. Approximately 25% of RCC will recur by 4 years postoperatively. Clinicians should cautiously screen patients with symptomatic RCC, regardless of lesion size for AI.

Abstract
Whether a mixed type of craniopharyngioma (CP) exists and whether papillary craniopharyngioma (pCP) is on a histopathological continuum with Rathke's cleft cyst (RCC) remain controversial. Herein, we examined the expression and localization of β-catenin, BRAF p.V600E (V600E), and triggering receptor expressed on myeloid cells-1 (TREM-1) in 58 samples including 20 pCPs, 26 adamantinomatous craniopharyngiomas (aCP), and 12 RCCs. Five aCPs were diagnosed with mixed type CPs and the remaining 21 cases were pure aCPs. Four of the 12 RCCs presented with significant squamous epithelium (SE). V600E immunoreactivity was observed in all pCPs in the cytoplasm, but not in the nuclei. aCPs and RCCs, including mixed type CP, did not express V600E. Nuclear β-catenin translocation was detected exclusively in aCPs. TREM-1 was expressed in pCPs. Additionally, TREM-1 expression was detected in the SE of 5 “mixed type” CPs, while it was absent in pure aCPs. TREM-1 was expressed in 4 RCCs with SE, but not in the remaining 8 RCCs. TREM-1 mRNA levels were compared in cultured pCP and aCP cells. TREM-1 mRNA level was significantly (p < 0.001; up to 4.045 fold) higher in pCPs than in aCPs. Western blotting revealed a significantly (p < 0.001; up to 7.19 fold) lower level of TREM-1 expression in aCP cells compared to that in pCP cells. Our findings further supported that RCC and pCP may represent two ends of a morphological spectrum. A variant showing overlapping histological features of aCP and pCP should not be considered as a mixed type.

Abstract
BACKGROUND Rathke's cleft cysts generally remain asymptomatic throughout life, but a few patients may suffer severe neurological and/or endocrinological deficits. The symptoms include visual disturbances caused by compression of the optic chiasm, and severe endocrinological deficits caused by repeated intracystic hemorrhage or leakage of cyst content. However, no case of Rathke's cleft cyst has infiltrated into neuroglial tissue with marked cerebral edema. CASE PRESENTATION Two patients presented with non-infectious re-deterioration of Rathke's cleft cysts with intraparenchymal infiltration and marked cerebral edema, to ipsilateral hypothalamus in one case and to the bilateral frontal lobes in the other. Both patients were surgically treated by extended transsphenoidal surgery, and showed remarkable improvement with postoperative pulse-dose steroid therapy, including disappearance/shrinkage of abnormal enhanced lesion and cerebral edema on magnetic resonance imaging. Histological examination disclosed significant squamous metaplasia in epithelia and marked infiltration of inflammatory cells into the pituitary gland and neuroglial tissues. Most infiltrated cells were lymphocytes and plasma cells, thought to indicate the involvement of long-term underling inflammatory processes in this phenomenon. CONCLUSION Long-term subclinical inflammation may be the mechanism of this extraordinary aggressive clinical course. Postoperative steroid administration should be reduced prudently, and careful follow-up imaging is essential in cases of Rathke's cleft cyst with abnormal histological findings.

Abstract
BACKGROUND It is not known when surgery is appropriate for the treatment for incidental Rathke cleft cysts because knowledge of their natural history is lacking. In this study, we sought to determine whether symptomatic Rathke cleft cysts could be distinguished by their signal intensities in magnetic resonance (MR) images. We analyzed the relationship between these signal intensities and clinical manifestations of the cysts and their patterns of expansion. METHODS MR signal intensities on T1-weighted (T1W) and T2-weighted (T2W) images for 52 cases were categorized into 3 types. Type 1 (20 cases) showed low signal intensities on T1W images and hyperintensity on T2W images. Type 2 (10 cases) showed hyperintensity on both T1W and T2W images. Type 3 (22 cases) showed hypointensity on T2W images. RESULTS A significantly higher proportion of patients with type 1 signal intensities had large cysts compressing their third ventricle than patients with the other 2 types of signal intensities. Patients with type 1 signal intensities also frequently had visual disturbances. Anterior pituitary dysfunction was observed more often in patients with type 2 or 3 signal intensities than in patients with type 1 intensities. CONCLUSIONS We conclude that Rathke cleft cysts that show an MR signal intensity similar to that of cerebrospinal fluid grow slowly and are frequently diagnosed as cysts associated with visual disturbance when they become large. It may be possible to predict the clinical progression of Rathke cleft cysts by assessing MR signal intensities.

Abstract
OBJECT Rathke's cleft cysts (RCCs) are benign lesions with a location that is entirely intrasellar, intrasellar with suprasellar extension (intrasuprasellar), or purely suprasellar. The recurrence of RCC is relatively uncommon. The present study was conducted to report clinical characteristics, histological features, and outcomes based on location of the cyst with a primary focus on analyzing the predictors of squamous metaplasia and recurrence in these 3 types of RCCs. METHODS A retrospective review of the medical records of patients with symptomatic RCCs who had undergone resection at the authors' institution was conducted. Data points, including clinical presentation, preoperative endocrine status, operative details, imaging findings, pathology, and clinical outcomes, were reviewed. A multivariable regression model was used to identify predictors of recurrence. RESULTS The mean age of the 87 eligible patients, 64 females and 23 males, was 41 ± 14 years (range 10-73 years). Sixteen patients (18%) had an entirely intrasellar RCC, 21 (24%) had a purely suprasellar cyst, and 50 (58%) had an intrasuprasellar RCC. The mean cyst volume was 2.4 ± 0.9 cm(3) (range 0.36-4.9 cm(3)). Headache was the most frequent initial symptom (76%) followed by visual disturbance (45%). The transsphenoidal approach was performed for all intrasellar RCCs (16 cysts) and 33 of 50 intrasuprasellar RCCs. The transcranial route was used for all suprasellar cysts (21 cysts) and 17 of 50 intrasuprasellar RCCs. Squamous metaplasia was present in 27 (31%) of 87 RCCs. The occurrence of squamous metaplasia was associated with cyst location (p = 0.027), T1 signal intensity (p = 0.004) and ring enhancement on Gd-enhanced MRI (p = 0.017), and cyst volume (p = 0.045). A suprasellar location (p = 0.048, OR 3.89, 95% CI 1.010-15.020), ring enhancement on Gd-enhanced MRI (p = 0.028, OR 3.922, 95% CI 1.158-13.288), hypointensity on T1-weighted MRI (p = 0.002, OR 6.86, 95% CI 1.972-23.909), and cyst volume (p = 0.01, OR 0.367, 95% CI 0.170-0.789) were independent predictors of squamous metaplasia. The mean time to reaccumulation (11 [12.6%] of 87 cases) and recurrence (7 [8%] of 87 cases) was 14 ± 6 months. Recurrence-free survival was 84.5% at a mean of 98.2 ± 4.6 months after treatment. A suprasellar cyst location (p = 0.007, OR 7.7, 95% CI 1.75-34.54), the occurrence of squamous metaplasia (p = 0.007, OR 19.3, 95% CI 2.25-165.18), and isointensity on T2-weighted MRI (p = 0.041, OR 10.29, 95% CI 1.094-96.872) were the independent predictors of RCC recurrence. CONCLUSIONS A suprasellar cyst location, the occurrence of squamous metaplasia, and isointensity on T2-weighted MRI were independent predictors of RCC recurrence. The extent of resection and type of surgical approach used were not associated with recurrence. A tailored extent of resection based on cyst location and predictive factors is recommended.

Abstract
Both Rathke's cleft cyst and craniopharyngioma are considered to arise from the remnants of Rathke's diverticulum despite the quite different histological characteristics. These two lesions may consist of a disease spectrum extending from Rathke's cleft cyst to craniopharyngioma. However, in spite of increasing evidence of these intermediate histologies, very few cases of the actual transformation from Rathke's cleft cyst to craniopharyngioma have been reported in the same patient. A 47-year-old man suffered from recurrent visual dysfunction. Aspiration and partial cystectomy was performed to a suprasellar massive cystic lesion. The histological diagnosis was Rathke's cleft cyst with a small component of squamous metaplasia. Seven months later, the cyst was re-expanded. The cyst wall was irregularly thickened. Re-operation was performed, and the thickened anterior wall was widely removed. Postoperative histological examination showed multiplication of stratified squamous epithelia forming a papillary arrangement. Ki-67 staining showed positive cells randomly distributed not only in the basal layer but also in various epithelial layers, with a labeling index of more than 20 %. The histological diagnosis was squamous papillary type of craniopharyngioma with high potential of proliferation. Subsequent immunohistochemical examinations showed positive reaction to cytokeratin 8 only in the initial epithelium and negative in the latter epithelium. The present case was thought as an actual evidence of the proposed link between Rathke's cleft cyst and craniopharyngioma. Cytokeratin 8 could be the important examination to differentiate Rathke's cleft cyst from craniopharyngioma.

Abstract
OBJECT An assessment regarding both surgical approaches and the extent of resection for Rathke cleft cysts (RCCs) based on their locations has not been reported. The aim of this study was to report the results of a large series of surgically treated patients with RCCs and to evaluate the feasibility of individualized surgical strategies for different RCCs. METHODS We retrospectively reviewed 87 cases involving patients with RCCs (16 intrasellar, 50 intra- and suprasellar, and 21 purely suprasellar lesions). Forty-nine patients were treated via a transsphenoidal (TS) approach, and 38 were treated via a transcranial (TC) approach (traditional craniotomy in 21 cases and supraorbital keyhole craniotomy in 17). The extent of resection was classified as gross-total resection (GTR) or subtotal resection (STR) of the cyst wall. Patients were thus divided into 3 groups according to the approach selected and the extent of resection: TS/STR (n = 49), TC/STR (n = 23), and TC/GTR (n = 15). RESULTS Preoperative headaches, visual dysfunction, hypopituitarism, and diabetes insipidus (DI) resolved in 85%, 95%, 55%, and 65% of patients, respectively. These rates did not differ significantly among the 3 groups. Overall, complications occurred in 8% of patients in TS/STR group, 9% in TC/STR group, and 47% in TC/GTR group, respectively (p = 0.002). Cerebrospinal fluid (CSF) leakage (3%), new hypopituitarism (9%), and DI (6%) were observed after surgery. All CSF leaks occurred in the endonasal group, while the TC/GTR group showed a higher rate of postoperative hypopituitarism (p = 0.7 and p < 0.001, respectively). It should be particularly noted that preoperative hypopituitarism and DI returned to normal, respectively, in 100% and 83% of patients who underwent supraorbital surgery, and with the exception of 1 patient who had transient postoperative DI, there were no complications in patients treated with supraorbital surgery. Kaplan-Meier 3-year recurrence-free rates were 84%, 87%, and 86% in the TS/STR, TC/STR, and TC/GTR groups, respectively (p = 0.9). CONCLUSIONS It is reasonable to adopt individualized surgical strategies for RCCs based on cyst location. Gross-total resection does not appear to reduce the recurrence rate but increase the risk of postoperative complications. The endonasal approach seems more appropriate for primarily intrasellar RCCs, while the craniotomy is recommended for purely or mainly suprasellar cysts. The supraorbital route appears to be preferred over traditional craniotomy for its minimal invasiveness and favorable outcomes. The endoscopic technique is helpful for either endonasal or supraorbital surgery.

Abstract
BACKGROUND Rathke's cleft cyst (RCC) with significant squamous and/or stratified epithelium including smooth transition from single cuboidal to squamous epithelium (tRCC) is rare and possibly represents an intermediate form to craniopharyngioma. METHODS Twelve patients with histologically confirmed tRCC were retrospectively investigated from a series of 167 cases of RCC and 96 cases of craniopharyngiomas. Clinical data were reviewed, and immunohistochemistry findings for cytokeratins and β-catenin were examined. RESULTS All lesions were located in the sella turcica with marked extension to suprasellar cistern. Six of the 12 patients had suffered postoperative re-enlargement, and three of these six patients required more than two additional operations and irradiation. CAM5.2 was positive in the glandular epithelium in all tRCCs and focally positive in the squamous epithelium of all these tRCCs. 34βE12 was positive in the squamous epithelium in all tRCCs and focally positive in the glandular epithelium in all but one tRCC. The findings of cytokeratin expression of tRCCs were very similar to those of craniopharyngioma. β-Catenin showed nuclear translocation in five cases. All patients with nuclear translocation of β-catenin suffered postoperative re-enlargement. CONCLUSIONS tRCC carries an extremely high risk of re-enlargement. Cytokeratin expression resembles that in craniopharyngioma, which might indicate a very close origin of these pathologies. Nuclear translocation of β-catenin may be related to the aggressive clinical course.
