Abstract
Originally pioneered in adults, endoscopic endonasal approaches for skull base pathology are being increasingly applied as a minimally invasive alternative for young children. Intrinsic anatomic differences between these patient populations have sparked discussions on the feasibility, safety, and efficacy of these techniques in pediatric patients. This work aims to serve as a primer for clinicians engaged in the rapidly evolving field of pediatric endoscopic skull base surgery. A succinct overview of relevant embryology, sinonasal anatomy, and diagnostic workup is presented to emphasize key differences and unique technical considerations. Additional discussions regarding select skull base lesions, reconstructive paradigms, potential surgical complications, and postoperative care are also highlighted in the setting of multidisciplinary teams.

Abstract
Not every Rathke's cleft cyst (RCC) is confined within the sella between the posterior and anterior lobes of the pituitary gland. Intracranial ectopic RCCs are extremely rare, with only seven cases reported in the literature. In this study, the authors presented a rare case of a symptomatic ectopic retrosellar RCC posterior to the pituitary gland, causing extensive clival erosion. The surgical nuances of the wide marsupialization of the cyst through intraoperative ultrasound-assisted endoscopic endonasal transclival approach are described, and a systematic literature review of intracranial ectopic RCCs is conducted.

Abstract
BACKGROUND The postoperative recurrence of cystic lesions of the sella is frequent and may require further surgery for re-drainage. OBJECTIVE To tackle this problem, we propose to insert a small cross-shaped drain coursing from the cyst lumen to the suprasellar cistern. At this early stage of innovation, the technique is primarily intended for patients who present with a recurrence. METHODS The cruciform drain is fashioned from the tip of a ventricular catheter and is inserted under endoscopic vision. We retrospectively reviewed the pre- and postoperative records of patients in whom this technique was implemented. RESULTS A cruciform drain was placed in five patients since the introduction of the technique into our practice in 2018. The use of the cruciform drain did not impact upon the expected surgical workflow nor was it associated with adverse intraoperative events, but three patients did develop a postoperative CSF leak that was successfully treated in all cases. None of the patients showed re-collection of their cysts on early radiological follow-up. CONCLUSION The cruciform drain is intended to prevent the renewed build-up of cystic fluid by allowing it to flow through and around the drain into the subarachnoid space. We have modified our repair protocol in response to the observed high CSF leak rate, as a basis for further development of the technique. Studies involving long-term follow-up will also be required to assess its efficacy in reducing cyst recurrence.

Abstract
BACKGROUND Rathke's cleft cysts (RCCs) are benign tumors of the pituitary gland. Small, asymptomatic RCCs do not require surgical treatment, whereas surgical treatment is required for symptomatic RCCs. METHODS We retrospectively reviewed medical records of patients with an RCC who were diagnosed and managed in our institution between April 2004 and April 2020 and generated two different cohorts: the observation (n=114) and the surgical group (n=99). Their initial MRI signal characteristics were analyzed. The natural course focusing on cyst size was observed in the observation group and postoperative visual and endocrine outcomes were evaluated in the surgical group. RESULTS The characterization of MRI signals of cyst contents in both T1-weighted (T1W) and T2-weighted (T2W) images revealed nine combinations for our 213 patients. Among 115 patients with a high T2W signal, the cysts showed hypo-, iso-, and hyper-intensity on T1W images in 72, 39, and 44 patients, respectively; Type S-low, Type S-iso, and Type S-high. One more major group of 35 patients showed RCCs with hyperintensity on the T1W images and hypointensity on the T2W images named as Type M. In the comparison between observation and surgical groups, we identified only two major groups in which the number of patients in the surgical and observation groups was statistically different: more Type S-low in a surgical group (p<0.001) and more Type M in an observation group (p=0.007). In subgroup analysis, the range of change in the cyst size was the highest in Type S-high in the observation group (p=0.028), and intergroup differences in visual and endocrine outcomes were not evident in the surgical group. CONCLUSION MRI characteristics help to predict the natural course of RCCs. We identified subgroups of RCCs which are more or less likely to require surgical intervention.

Abstract
Pituitary Incidentalomas (PI) are pituitary lesions serendipitously identified on imaging. PIs have become common in clinical practice because of increased use of imaging and radiologic advances. The most frequently incidentally detected lesions in adults are pituitary adenomas, followed by cystic lesions, and rarely other types of tumors and infiltrative and inflammatory disorders. Biochemical screening for hyperprolactinemia and acromegaly is needed in all patients with PI, whereas testing for hyposecretion is recommended for lesions larger than 6.0 mm. Most PIs are small nonfunctioning adenomas or cysts, which can be conservatively managed. For larger lesions, a multidisciplinary approach including endocrinology, neurosurgery, and neuro-ophthalmology is required. For incidentally detected lactotroph, somatotroph, and corticotroph adenomas, disease-specific management guidelines apply. Prospective studies are needed to enhance our understanding of the long-term course and response to treatment.

Abstract
Abstract
Background
A Rathke’s cleft cyst is a benign intrasellar cystic lesion, with suprasellar extension reported in a few cases. An entirely suprasellar Rathke’s cleft cyst without any intrasellar component, though previously reported, is rare.
Case presentation
We report a case of an entirely suprasellar Rathke’s cyst in a 25-year-old female presenting with headache and visual complaints. The patient was treated surgically by drainage of the cyst and removal of the cyst wall by transcranial approach. Histopathology and immunohistochemistry confirmed the diagnosis of Rathke’s cyst. We review the relevant literature and discuss its neuroembryologic pathogenesis, pathology and the factors influencing the recurrence of the cyst.
Conclusions
To the best of our knowledge, only 62 cases of an entirely suprasellar Rathke’s cyst have been reported till date.

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
PURPOSE T2 hypointense signal at the posterior edge of the adenohypophysis (T2HSPA) on magnetic resonance imaging (MRI) is incidentally encountered. We aimed to investigate the prevalence and morphology of T2HSPA and their relationship to age. METHODS A total of 212 cases between 3 and 88 years old were examined. Sagittal T2-weighted image (T2WI) was evaluated for the presence of T2HSPA, which classified by its morphology into two types (belt-like or nodal). The Wilcoxon rank sum test and chi-square test were used to evaluate the differences between the groups. The T2HSPA was extracted by ImageJ software and measured as a cross-sectional area (CSA) quantitatively by threshold setting. We examined the relationship between CSA of T2HSPA and age, and Spearman's correlation coefficients were used for statistical analysis. RESULTS Of the 212 cases, 80 (37.7%) were identified with T2HSPA. The groups with T2HSPA were significantly younger than the groups without it (p = .01). Groups with belt-like T2HSPA were significantly younger than the groups with nodal T2HSPA (p = .01). There was a weak negative correlation between CSA of T2HSPA and age (p = .02). CONCLUSION T2HSPAs were incidentally detected in 37.7% of all cases, tended to be more common in younger cases, and their morphology was related to age. They seem to have little clinical significance as they tend to decrease in size with age.

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
Background: Rathke cleft cyst (RCC) apoplexy is an uncommon type of lesion that is challenging to diagnose without histopathological samples. Very few articles have been published describing the details of RCC apoplexy. We studied a good number of published articles to analyze its demographics, clinical and hormonal presentations, and outcomes. Methods: A literature review of English language publications about RCC apoplexy or pituitary apoplexy was conducted using Medline and EMBASE search engines. Thirty articles with histological diagnosis of RCC apoplexy were identified, the earliest of which was published in 1990 and the latest in 2019. We combined the findings of these articles with our own case report and then compared the demographics, clinical and hormonal presentations, and outcomes between RCC apoplexy and pituitary adenoma apoplexy. Results: Our data included 29 patients with RCC, with a mean age of 36.87 years (8–72) and a predominance of female patients (68%). The hemorrhagic type was most common, reported in 86%. Headache was the most common presenting symptom, being reported in 93% followed by hypogonadism (73%) and hormonal deficits (52%). All but three patients improved neurologically (90%); however, 45% of patients required long-term hormonal replacement, mostly thyroid hormone. No cases of worsening neurological or hormonal status were reported. Conclusion: RCC apoplexy presents with less severe neurological and hormonal abnormalities than pituitary adenoma apoplexy; it also has a better prognosis in endocrine functional recovery. We recommend applying current management guidelines of pituitary adenoma apoplexy to RCC apoplexy.

Abstract
PURPOSE To evaluate the ophthalmic features of Rathke's cleft cyst (RCC) and its association with radiological characteristics. METHODS In this retrospective single-center study, patients who showed typical findings suggestive of RCC on magnetic resonance imaging (MRI) and underwent relevant ophthalmic examination were recruited retrospectively. Patients were stratified into two groups according to the presence or absence of ophthalmic symptoms related to RCC. We reviewed patients' demographic information, initial symptoms, endocrinological status, ophthalmic features, and characteristics of MRI. Height, size and location of RCC, as well as the optic chiasm displacement assessed from MRI. RESULTS Thirty-three patients (20 women and 13 men) were included in this study from among 335 patients with RCC on MRI. Fifteen patients had ophthalmic manifestation related to the cyst (Ophthalmic group), whereas 18 patients were not (Non-ophthalmic group). Headache was the most common initial symptom (15 patients, 45.5%), followed by visual disturbance (7, 21.2%), diplopia (1, 3.0%), retro-orbital pain (1, 3.0%), galactorrhea (1, 3.0%), and peripheral extremity discomfort (1, 3.0%). In seven asymptomatic patients (21.2%), the lesion was an incidental finding during a regular medical examination. Ophthalmic manifestation included visual field defect (14 patients, 93.3%) and diplopia (1 patient, 6.7%). The height, volume, and the coronal and sagittal displacements were larger in the ophthalmic group (P < .001, all). Eleven patients who manifested ophthalmic symptoms underwent excision surgeries and nine of them (81.8%) experienced visual function improvement. CONCLUSION Appropriate ophthalmic examinations are warranted in patients with RCC, and treatment should be actively considered in patients with ophthalmic manifestations.

Endoscopic endonasal cyst fenestration into the sphenoid sinus using the mucosa coupling method for symptomatic Rathke's cleft cyst: a novel method for maintaining cyst drainage to prevent recurrence. J Neurosurg 2020; 133:1710-1720.

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
PURPOSE We aimed to evaluate the frequency and neuroimaging features of Rathke's cleft cysts (RCCs) in children examined for endocrine-related diseases and to determine changes in the neuroimaging features of RCCs during the follow-up of children. We hypothesize that RCCs are being more commonly diagnosed in children with endocrine-related diseases and most of the RCCs show neither fluid intensity nor intensity due to high protein content on magnetic resonance imaging (MRI). METHODS After approval by the local ethics committee, the medical records and contrast-enhanced pituitary MRI of 833 children (boys/girls, 338/495; mean age±SD, 9.4±3.7 years) were retrospectively reviewed between January 2016 and January 2019. The size, location, signal intensities, and postcontrast enhancement pattern of RCCs were assessed by a pediatric radiologist. Same imaging features were also independently reviewed by another radiologist to determine the interobserver agreement by using the kappa statistics (κ) and intraclass correlation coefficient (ICC). RESULTS RCC was evident on MRI in 13.5% of the patients (boys/girls, 39/74; mean age±SD, 9.8±3.9 years). The mean size of RCCs was 5.5 mm (range, 3.1-8.5 mm). An RCC frequency higher than expected was found in patients with central precocious puberty, diabetes insipidus, and hypersecretion of prolactin (P = 0.007). The mean size of RCCs did not show significant differences among the clinical indications for MRI (P ≥ 0.461). All RCCs showed abnormal signal on T2-weighted image and most (89%) showed neither fluid intensity nor intensity due to high protein content (i.e., isointense on T1-weighted imaging and hypointense on T2-weighted imaging compared with the normal anterior pituitary gland). Eighty-four patients with RCCs (74%) had follow-up MRI and the mean follow-up was 1.5 years. In follow-ups, five RCCs disappeared; the mean size of 10 RCCs increased and that of 6 RCCs decreased. These size changes were not statistically significant (P = 0.376). No signal intensity changes of RCCs were seen during the follow-up, except for 4 RCCs, whose protein content increased over time and T1 signals increased on imaging. Interobserver agreements were almost perfect for the MRI findings of RCCs (κ and ICC range, 0.81-1, P < 0.001). CONCLUSION RCCs were not uncommon in patients examined for endocrine-related diseases, and nearly 1 in 10 patients had an RCC. The size and signal intensities of RCCs may change over time and the evolution of RCCs is unpredictable. Most RCCs showed neither fluid intensity nor intensity due to high protein content on MRI, and all RCCs had an abnormal signal on T2-weighted imaging, thus eliminating the need to administer a contrast agent at follow-up imaging of the patients.

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 The authors present cystic epithelial masses in the suprasellar region which on histopathology revealed 4 mixed tumors having simple cuboidal epithelium of Rathke's Cleft Cyst (RCC) elements trapped within pituitary adenoma, epidermoid cyst, dermoid cyst, and papillary craniopharyngioma respectively. OBJECTIVE To highlight the developmental theory of ectodermal continuum in the realm of suprasellar epithelial cystic lesions and examines the cardinal aspects that distinguish RCC from its confounder, ciliary craniopharyngioma. METHODS The authors performed a medical chart review on 4 patients who had coexisting RCC with craniopharyngioma, pituitary adenoma, suprasellar dermoid, and epidermoid cysts. RESULTS This series of unique suprasellar lesions elucidate the spectrum of cases from Rathke's cyst to other suprasellar epithelial cysts including a recently identified clinical entity called ciliary craniopharyngioma, which authors feel is a misnomer. The authors also report the first case of ruptured dermoid cyst admixed with elements of Rathke's cyst elements and xanthogranuloma in neurosurgical literature. CONCLUSION We propose that the new entity of ciliary craniopharyngioma could be just another variant of RCC elements nested within a typical papillary or adamantinomatous lesion. Further study is warranted to understand the implications of natural history with tumors containing RCC elements.

Abstract
BACKGROUND Pituitary pars intermedia/Rathke cleft cysts or cyst-like structures are commonly encountered in children undergoing brain magnetic resonance imaging (MRI), especially when examinations include thin-section, high-resolution sequences. OBJECTIVE To determine the prevalence of pituitary cystic lesions in children at our institution using modern MRI technique, to assess for associated endocrinopathy and to address the need for follow-up. MATERIALS AND METHODS We retrospectively reviewed 232 consecutive 1.5- and 3-T brain MRIs in children ages 0-18 years (mean: 8.3±5.3 years). We evaluated 3-D volumetric T1 spoiled gradient echo (SPGR) and axial T2-weighted sequences. Pituitary glands were evaluated for the presence, size and signal characteristics of cysts. Cyst volumes were measured in three orthogonal planes. Endocrine abnormalities were documented from the medical record. RESULTS Pituitary cysts were present in 57.7% of children (n=134), with a mean linear measurement of 3.6±1.17 mm (range: 0.4 to 12.3 mm). The overwhelming majority of cysts were hyopointense on T1-W images (n=121, 90%) and isointense on T2-W images relative to the adenohypophysis (n=106, 79%). T1 hyperintense and T2 hypointense signals were present in a minority, 6.7% and 8%, respectively. Most cysts were occult on post-contrast T1-W images (n=24, 77%). Endocrine abnormalities were present in 2/134 (1.5%) of children with cysts (these were unrelated to the pituitary gland) versus 1/98 (1%) children without cysts (P=0.7). CONCLUSION More often than not, pituitary cysts/cyst-like structures can be found incidentally in children using modern MRI techniques. Follow-up is not typically required if there are no associated symptoms or excessive size.

Abstract
Background A wide spectrum of non-neoplastic cystic lesions can occur in the central nervous system (CNS). These are uncommon, benign and of diverse aetiology, pathogenesis and clinical presentation.The spectrum of these lesion varies based on the location and in turn histogenesis. Objectives To evaluate the pathologic spectrum of non-neoplastic cystic lesions in the CNS (both developmental and acquired) and highlight the role of histopathology in the diagnosis of these cystic lesions. Settings and Design This was a retrospective study done at Department of Neuropathology,NIMHANS. Materials and Methods All the histologically diagnosed non-neoplastic cystic lesions of CNS submitted to the Department of Neuropathology between 2014 and 2017 were reviewed in this study. The data was analysed in relation to the type of cysts, location(intracranial and spinal), and clinical profile using SPSS software version 17.0. Results The study included 538 cases with patient age ranging from 5 months to 90 years [M:F:1:1.05]. Non-infective cysts (489/538, 90.8%) predominated over the infective cysts (49/539, 9.2%) with epidermoid cysts (132/538, 24.5%) being the most frequent one followed by colloid cysts (126/538, 23.4%) and arachnoid cysts (111/538,20.6%). The most common infective cyst was neurocysticercosis (42/538, 7.8%) followed by hydatid cyst (7/538, 1.3%). Intracranial cysts (415/538, 77.1%) were more common than spinal ones (123/538, 22.9%). Conclusions: A variety of cystic lesions occur in the CNS with overlapping clinical features, image findings and lining. Hence, histological analysis plays a crucial role in the evaluation of these lesions.

Abstract
BACKGROUND Management of recurrent Rathke cleft cysts (RCC) is problematic. The mainstay of treatment has been reoperation with cyst drainage. Radical cyst resection, although effective, results in a high incidence of diabetes insipidus. Several case reports suggest a potential benefit to radiation therapy or the use of intracystic bleomycin. The intracystic application of bleomycin is known to be beneficial in the treatment of cystic craniopharyngioma; however, its usefulness in the treatment of recurrent RCC has yet to be proven. OBJECTIVE To present our 6-yr experience using intracystic bleomycin for recurrent RCC. METHODS We performed a retrospective chart review of patients with RCC who underwent surgical resection between January 2010 and May 2016 by a single surgeon. Specific attention was paid to patients with recurrent RCC. RESULTS Of the 59 patients operated on for RCC during this 6-yr interval, 6 patients with symptomatic recurrent RCC were identified and received intracystic bleomycin at the time of reoperation. To date, no symptomatic cyst recurrence has been documented in the patients receiving bleomycin (mean = 38.8 mo, range 21.2-79.8 mo). CONCLUSION The use of intracystic bleomycin appears to be a safe and potentially effective treatment option in patients with recurrent RCC. Additional studies with longer follow-up are needed to further define the role of bleomycin in recurrent RCC.

Abstract
INTRODUCTION Treatment of childhood brain tumors, including surgical resection and especially external beam radiation, often results in endocrine complications manifested by hypopituitarism, which can involve growth hormone deficiency, hypothyroidism, adrenal insufficiency, disorders of puberty, diabetes insipidus, and hypothalamic obesity. AREAS COVERED A comprehensive literature search was conducted on Medline (publications from the 1990s to 01/2019) including systematic reviews, meta-analyses, longitudinal controlled studies, retrospective cohort studies, and case reports. Herein, we present an up-to-date review of the current literature regarding endocrine sequellae of childhood brain tumor survivors. EXPERT OPINION Late endocrine sequellae can arise many years after the initial treatment of tumor, so at least annual surveillance of growth, puberty, weight, development, and endocrine status is recommended for at least 10 years after tumor therapy. This follow up should encompass childhood and adulthood among survivors. If found early, outcomes of endocrinopathies are favorable when treated appropriately. Newer tumor therapy modalities, such as proton beam radiation, offer the potential for fewer endocrine complications, but such benefit has yet to be demonstrated, and more research into short- and long-term outcomes is needed.

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
OBJECTIVES Rathke cleft cysts (RCCs) are rare, benign lesions formed from remnants of Rathke pouch during embryologic development. However, following marsupialization, maintaining tract patency remains a challenge. Several techniques for decreasing stenosis have been described, including free mucosal grafting, silastic spacing, and using steroid-eluting stents. Nasoseptal flaps (NSFs) have a reliable vascular supply and are widely utilized in skull base reconstruction. We present a novel technique to maintain patency of the marsupialized RCC cavity by lining it with an NSF to promote long-term drainage and re-epithelialization of the RCC cavity. METHODS Retrospective chart review of all patients who underwent surgery for symptomatic RCCs. These patients underwent endoscopic endonasal surgery between February 3, 2016, and June 12, 2018, with marsupialization followed by circumferential NSF lining. Primary outcomes include symptomatic control, surgical complications, and RCC cavity patency. RESULTS Seven patients underwent RCC marsupialization with no intraoperative cerebrospinal fluid leak, followed by circumferential lining of the marsupialized cavity with an NSF. In each case, no cyst re-accumulation or recurrent symptoms were noted, and the NSF lining provided long-term patency of the tract in all cases to a mean of 6.7 ± 10.1 months of follow-up, including one patient with sustained patency at 29 months follow-up. CONCLUSION Utilization of the NSF to "stent open" the RCC cavity following marsupialization is a safe and effective means to prevent restenosis. Advantages include sustained patency of RCC cavity for complete drainage and a dependable vascular supply. LEVEL OF EVIDENCE 4 Laryngoscope, 129:2258-2261, 2019.

Abstract
Rathke's cleft cysts (RCC) are sellar-suprasellar cysts that are usually discovered incidentally given their indolent clinical course. When symptoms do arise, the most common clinical presentation is headache, visual field deficits due to visual pathway compression, diplopia due to cavernous sinus compression, chemical meningitis due to spillage of the cyst contents, endocrine dysfunction, and very rarely apoplexy. We present 2 cases of RCC in sisters who developed a sudden onset of symptoms in a manner similar to pituitary apoplexy. Interestingly, one of them had a very unusual presentation with seizure. We hypothesize that acute symptoms occur due to aggressive intracystic overproduction of mucopolysaccharides (with or without hemorrhage) and a resulting compressive syndrome or local irritation of surrounding structures by spillage of the cyst contents. RCC can be encountered incidentally in family members or may have a familiar predisposition. Since both sisters presented here developed apoplexy symptoms, we propose a more frequent follow-up with sequential imaging in patients with a family history of RCC. Transsphenoidal surgery with evacuation of the cyst contents is the treatment modality of choice, with excellent outcomes.

Abstract
BACKGROUND Rathke cleft cysts (RCC) are benign, epithelium-lined intrasellar and/or suprasellar cysts believed to originate from the remnants of the Rathke pouch. The aim of this study was to analyse the symptoms and surgical outcome of patients with the diagnosis of RCC verified in a histopathological examination of the postoperative material. METHODS The study is a retrospective analysis of 38 cases of children who underwent a neurosurgical treatment due to RCC at the Children's Memorial Health Institute in Warsaw, Poland, between 1994 and 2015. RESULTS At diagnosis, the mean age was 13 years and 8 months (6 years and 11 months-17 years and 10 months, sex ratio was 1:0.9 with a female prevalence). The most common symptoms were the following: headache (50%), hypothyroidism (50%), short stature and/or decreased growth velocity (47%), delayed puberty and menstrual abnormalities (37%), diabetes insipidus or polydipsia and polyuria (26%), adrenal dysfunction (26%), sleepiness and general weakness (13%) and visual disturbances (11%). Due to the gravity of symptoms and size of the lesion, all the patients underwent a surgical treatment. All but one were successful (one patient died due to postoperative neurosurgical complications). The most common postoperative complications were the following: adenohypopituitarism (67%) and diabetes insipidus (45%). CONCLUSIONS RCC can present with serious symptoms that significantly deteriorate patients' quality of life. Despite a successful neurosurgical treatment in most of the analysed cases, patients required long-term pharmacological treatment.

Abstract
BACKGROUND: During the examination of the sellar region by magnetic resonance imaging, hyperintensity in T1 weighted is a common finding. This signal intensity has different sources, and its significance depends on the clinical context. Pathologic variations in T1 signal hyperintensity may be related to clotting of blood (pituitary apoplexy) or the presence of a high concentration of protein (Rathke cleft cyst). The purpose of this study is to describe the significance of intracystic nodule, a diagnostic characteristic found in Rathke’s cleft cyst, on MRI. CASE REPORT: We will present the case of a 20–year-old girl which referral to our hospital for head examination with magnetic resonance imaging because she has a post-traumatic headache. Pathological findings presented in T1-weighted hyperintensity intrasellar which persist even in T1 weighted-Fat suppression. These changes signal the presence of methemoglobin imposes. The patient is a referral to laboratory tests which result in rate except for slight value increase of prolactin. Recommended controller examination after a month but finding the same results which exclude the presence of methemoglobin. CONCLUSION: Morphological characteristics and signal intensity can impose the presence of high concentration of protein (Rathke cleft cyst).

Abstract
OBJECTIVE Rathke cleft cysts (RCCs) are sellar lesions that are commonly encountered in adults but infrequently diagnosed in the pediatric population. As a result, the optimal management of pediatric RCCs remains a subject of controversy. Only 2 prior surgical series have been published on pediatric RCCs and no study has compared the presentation and outcomes of surgically versus conservatively managed cases. The authors therefore performed a comparative analysis of pediatric cases of RCC in which patients were treated with surgery or managed in a conservative manner. METHODS All cases involving pediatric patients diagnosed with an RCC at the University of Virginia between 2000 and 2016 were included in this study. Patient medical records, operative notes, and neuroimaging findings were reviewed. Patients who developed visual field deficits, radiographic evidence of chiasmal compression, or medically refractory headaches were considered candidates for surgical intervention. All patients who were selected for surgery underwent an endoscopic endonasal approach with cyst fenestration. RESULTS A total of 24 pediatric patients were diagnosed with an RCC over a 16-year period. Seven patients ultimately underwent transsphenoidal cyst fenestration, and 17 were managed conservatively. The patients' age at diagnosis, cyst size, and pituitary function at the time of RCC diagnosis were similar in the conservatively and surgically managed cohorts. At diagnosis, 19 of 24 patients endorsed headaches that led to neuroimaging. All patients in the surgical cohort endorsed severe headaches at diagnosis compared with 71% in the conservative group. For the 7 patients treated with surgery, complete cyst evacuation was achieved in 86% of cases. Transient postoperative endocrinopathy occurred in 4 (57%) of 7 surgically treated individuals and resolved in all cases. In the conservative cohort, 1 patient developed a delayed pituitary-related endocrinopathy. Headache resolution occurred in 5 (71%) of the 7 patients who underwent surgery and 7 (58%) of the 12 who were treated without surgery. Cyst recurrence was documented in 1 individual in the surgical cohort who underwent a subtotal cyst fenestration that ultimately required re-intervention. In the conservative cohort, spontaneous cyst shrinkage occurred in 35% of patients with a median time to regression of 23.5 months. CONCLUSIONS Pediatric RCCs are benign sellar lesions that often present with headaches. While cyst fenestration mitigates headaches in most patients, the majority of conservatively managed pediatric patients with RCCs will have spontaneous headache resolution. Furthermore, spontaneous RCC regression occurs in a substantial number of individuals. Thus, in the absence of optic compression, visual field deficit, or diagnostic uncertainty, many pediatric cases of RCC can be managed conservatively.

Abstract
PURPOSE Rathke's cleft cyst (RCC) is an asymptomatic benign lesion. With increased interest in pediatric endocrinology, the prevalence of RCCs in children is also increasing. However, the clinical relevance and proper management of RCC is not well defined in children. Therefore, we investigated the clinical manifestations and radiologic features of RCC in children and adolescents, as well as the natural progression of RCC. METHODS We retrospectively reviewed the medical records of 91 children and adolescents with RCC diagnosed with magnetic resonance imaging (MRI) in Severance Children's Hospital from January 2006 to December 2015. The clinical, hormonal, and imaging findings were analyzed in patient groups classified according to age. The size of each cyst was assessed in sixty patients who underwent follow-up MRI during the 2 years. RESULTS Female patients were predominant (64 vs. 27). The common clinical features at presentation were endocrine dysfunction (59.3%), headache (23.0%), and dizziness (4.4%). Symptoms related to endocrine disorders were more frequent in younger patients. In 7 patients managed surgically, the cysts were significantly larger and more frequently located in the suprasellar region. Of 60 nonsurgical patients with a follow-up MRI performed within 2 years after the diagnosis, the RCC size increased in about 26.7% (n=16). CONCLUSIONS Although 94.4% of the patients with RCC had clinical symptoms, surgery was performed in only about 7.5% of patients. RCC is associated with pituitary insufficiency, thus, baseline and follow-up endocrine function tests are required. Additionally, regular MRI follow-up is required in long-term period to monitor change in size.

Abstract
Context: Ectopic neurohypophysis (EN) refers to an interrupted, nonvisualized, and thinned out pituitary stalk with ectopic location of the posterior pituitary gland. Concurrent extra-pituitary cerebral and extra-cranial anomalies have been rarely reported in patients of EN. Aim: The aim of this study was to evaluate the magnetic resonance imaging (MRI) findings of extra-pituitary cerebral anomalies in pediatric patients of EN. Settings and Design: A hospital-based cross-sectional study was conducted in a tertiary care center. Subjects and Methods: The study group comprised eight pediatric patients of EN associated with extra-pituitary cerebral or vascular anomalies. Clinical and biochemical assessment was done in all patients. Results: Out of the total eight patients with EN, MRI showed interrupted pituitary stalk in five patients (62.5%) and nonvisible pituitary stalk in three patients (37.5%). Ectopic posterior pituitary bright spot was demonstrated in median eminence in six patients (75%), faintly visualized in one patient (12.5%) and nonvisualized in another one patient. Statistical significant association was noted between pituitary gland height and patient's body height with the pituitary gland volume (P < 0.001). Varied extra-pituitary cerebral anomalies encountered in our patients ranged from isolated anomalies such as optic nerve hypoplasia in three patients (37.5%), corpus callosum dysplasia in four patients (50%), agyria-pachygyria complex in two patients (25%), and intracranial vascular anomalies in two patients to syndromic association of tuberous sclerosis in one patient. Conclusion: Identifying and reporting of associated extra-pituitary cerebral anomalies in patients with EN are crucial in assessing the overall neurological outcome of such patients.

Abstract
BACKGROUND Rathke cleft cyst (RCC) is a rare cystic sellar entity, which is usually small in size and asymptomatic in most patients. RCC presenting panhypopituitarism and a cystic lesion with rim enhancement on magnetic resonance imaging is extremely rare. Therefore, it is easy to be misdiagnosed as pituitary abscess because of the similar clinical manifestations and neuroimaging changes. CASE SUMMARY We report a rare case of RCC masquerading as pituitary abscess clinically and radiologically with no evidence of central nervous system infection. The patient was initially suspected to be diagnosed with pituitary abscess, which was denied by the histopathological findings of RCC with no intraoperative drainage of abscess.We present an uncommon case of RCC masquerading as pituitary abscess in a 62-year-old Chinese male patient. The patient was admitted to Peking Union Medical College Hospital complaining of severe frontal pulsatile headache, visual acuity deficit, polyuria, polydipsia, and slight disturbance of consciousness. The biochemical and endocrinological examinations revealed severe hyponatremia and panhypopituitarism. Magnetic resonance imaging showed a sellar lesion with the apparent cystic change and rim enhancement. Accordingly, pituitary abscess was misdiagnosed at the beginning.The patient received hormone replacement therapy and underwent a trans-sphenoidal surgery. The surgical findings were uneventful. The histopathological examinations showed no infiltration of inflammatory cells or pus, and proved the lesion to be RCC. CONCLUSION Through this rare case, we aim to emphasize that the differential diagnosis of sellar lesions requires constant vigilance and that RCC may lead to clinical and radiological changes similar with pituitary abscess.

Abstract
INTRODUCTION Symptomatic Rathke cleft cysts (RCCs) are rarely detected in neuroradiological screening and are less commonly found in children than in adults. However, when RCCs are observed in children, it is important to carefully distinguish a RCC from a cystic craniopharyngioma (CP) even if surgically treated or conservatively followed up. METHODS We conducted a retrospective review of clinical data from 11 patients with symptomatic RCCs whose ages were under 18 years and compared the data with data from 15 age- and sex-matched patients with cystic CP who were treated at our institute. RESULTS The mean age of the patients with RCCs was 12.2 years (range, 6-18). There were six males and five females. As initial symptoms, nine patients presented with headache, while two each had impaired visual function, diabetes insipidus, and activity loss. The 14 patients with CP suffered from impaired visual function. Magnetic resonance imaging (MRI) mainly showed hyperintensity on T1-weighted images (WIs) and hypointensity on T2-WI in patients with RCC. However, patients with CP had characteristic hyperintensity on T2-WI. The average maximum diameter of the RCCs was 19.0 mm on average (range, 8-33 mm). The RCCs were thus significantly smaller than CPs (34.9 mm; range, 21-54 mm). The RCCs were usually oval or dumbbell-shaped and regular in appearance, while the larger CPs were lobular and irregular. A preoperative endocrinological evaluation revealed insufficiencies in four axes in five patients with RCC. Postoperative endocrinological status improved in three patients, remained unchanged in three, and worsened in one. The gonadotropin axis was damaged in a majority (nine) of the patients with CP preoperatively. Postoperative evaluation revealed deficits in five axes in 14 patients with CP, which is a significantly different trend than observed in patients with RCC. Eight patients underwent surgical procedures (transsphenoidal surgery (TSS) in four, craniotomy in four). Two of these patients experienced a recurrence of the cysts. One of these patients subsequently underwent two craniotomies followed by radiation and other underwent TSS. Among the three conservatively treated patients, two experienced a transient worsening of their symptoms along with cyst enlargement. However, none of the three conservatively treated patients required an operation. CONCLUSIONS When RCCs become symptomatic in children, the most common symptom they lead to is headache. The cysts are commonly small, regular, and oval in shape. Hypointensity of cyst contents on MRI is a characteristic of RCCs, which distinguishes them from CPs. Surgical intervention can be effective and lead to the relief of symptoms without a high rate of complications. However, there seems to be a relatively high recurrence rate following surgery. Thus, if the patient's symptoms remain minor, the surgical treatment option should be used only when prudent, as the patient's symptoms may improve over time.

Abstract
Rathke's cleft cysts (RCC) are sellar lesions that typically remain asymptomatic throughout life. Symptomatic patients present with headache, visual disturbance and/or pituitary dysfunction and are treated with resection. We present a 61-year-old woman diagnosed with RCC which was resected twice then recurred before undergoing spontaneous resolution. RCC are often managed without surgical intervention. Some of these lesions may spontaneously resolve without surgical intervention while others may become symptomatic. In patients with asymptomatic recurrent RCC conservative management is recommended. Spontaneous involution may occur following initial resection and recurrence of RCC.

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
INTRODUCTION Primary intracranial and sellar squamous cell carcinoma is an extremely rare entity, usually caused by malignant transformation of epidermoid cysts, or very rarely other non-malignant epithelial cysts. Malignant transformation of a Rathke's cleft cyst has never been described. CASE DESCRIPTION We present a 49-year-old male patient who presented with a 3-month history of progressive frontotemporal headaches. Imaging revealed a 1.2 cm cystic pituitary mass consistent with a hemorrhagic Rathke's cleft cyst. The patient underwent trans-sphenoidal resection of the pituitary cyst, and pathologic analysis revealed a squamous cell carcinoma lining a Rathke's cleft cyst. Extensive imaging and otorhinolaryngologic evaluation revealed no primary source for metastasis. CONCLUSIONS We feel this represents the first case of a patient with a pituitary lesion in which presentation and MRI imaging were consistent with Rathke's cleft cyst, yet histology revealed squamous cell carcinoma in situ.

Abstract
PURPOSE Intrasellar abscess is an uncommon cause of mass lesions in the sella turcica. Few cases have been reported in the literature, and much remains unknown about the etiology and diagnosis of these lesions. We sought to review a series of patients with intrasellar abscess encountered at our institution and identify defining characteristics of their presentation and management. METHODS We conducted a retrospective chart review for intrasellar infection cases associated with a mass lesion. Included cases had clear demonstration of a mass lesion on imaging with subsequent positive microbiological cultures. Clinical presentation, management, post-operative course, neuroimaging, microbiology, and any perturbations in serum pituitary biochemical markers were examined. RESULTS All examined patients had a history of antecedent transsphenoidal pituitary surgery within the preceding 10 months. All presented with headaches, three with progressive visual loss, one with meningismus, one with fever in the setting of an active cerebrospinal fluid leak, and one with fever, meningismus, hypotension, and progressive somnolence. No patient presented with acute endocrine abnormalities. A majority did not initially have any diffusion restriction present on MRI, but in one case we were able to track the evolution of diffusion restriction over sequential MRI scans. Two patients had complete resolution of presenting symptoms, while three experienced improvement or stabilization of their neurologic deficit. There were no mortalities. CONCLUSIONS Pituitary abscess remains a rare diagnosis that can be difficult to make and to confirm. In our series we found a strong association between culture-positive abscess and recent pituitary surgery. When present, prompt treatment with surgical drainage and aggressive post-operative antibiotics can lead to a favorable outcome.

Abstract
Rathke cleft cyst is described as benign intrasellar cyst. They are mostly small and asymptomatic; they may become large enough to cause symptoms by compression of intrasellar or suprasellar structures. We report on a case of spontaneous regression of a symptomatic RCC with subsequent recovery of preexisting endocrine dysfunction and resolution of headaches. A 60-year-old man complained about headaches. Laboratory investigation revealed a partial hypopituitarism with a slight central hypothyroidism without need for substitution. An MRI study showed a cystic, T2-hyperintense, sellar lesion compatible with a RCC. At one year follow-up, the patient had no complaints and the hormone work-up revealed a regression of the previous slight hypopituitarism. The MRI study showed a complete regression of the cystic lesion and a normal sized and shaped pituitary gland. The spontaneous regression of cystic sellar lesions is rare. The exact mechanism of the possible spontaneous involution of RCC is until now not well understood. However, spontaneous regression is possible and justifies the conservative therapy with regular clinical and radiological follow-up for asymptomatic patients or patients with symptoms not caused by the mass effect of these lesions.

Abstract
We report a rare patient with an intrasphenoidal Rathke's cleft cyst (RCC) and review the literature. RCC are benign epithelium lined cysts containing mucoid material, which typically occur in a location that is either entirely intrasellar, or intrasellar with suprasellar extension (intra-suprasellar). RCC in a completely extrasellar location are uncommon. An intrasphenoidal RCC is extremely rare with only two patients reported in the literature to date. Preoperative diagnosis is difficult due to the uncommon location and absence of any characteristic radiological features. However, it remains of utmost clinical relevance because it may limit the operative management to biopsy sampling of the cyst wall and drainage of the contents via the transsphenoidal route.

Abstract
Antibodies that recognize neo-epitopes in tumor cells are valuable tools in the evaluation of tissue biopsy or resection specimens. The VE1 antibody that recognizes the V600E-mutant BRAF protein is one such example. We have recently shown that the vast majority of papillary craniopharyngiomas-tumors that arise in the sellar or suprasellar regions of the brain-harbor BRAF V600E mutations. The VE1 antibody can be effective in discriminating papillary craniopharyngioma from adamantinomatous craniopharyngioma, which harbors mutations in CTNNB1 and not BRAF. While further characterizing the use of the VE1 antibody in the differential diagnosis of suprasellar lesions, we found that the VE1 antibody stains the epithelial cells lining Rathke's cleft cysts with very strong staining of the cilia of these cells. We used targeted sequencing to show that Rathke's cleft cysts do not harbor the BRAF V600E mutation. Moreover, we found that the VE1 antibody reacts strongly with cilia in various structures-the bronchial airways, the fallopian tubes, the nasopharynx, and the epididymis-as well as with the flagella of sperm. In addition, VE1 reacts strongly with the cilia of the ependymal lining of the brain and with the cilia-containing microlumens of ependymoma tumors. There is significant sequence homology between the synthetic peptide (amino acid 596-606 of BRAF V600E: GLATEKSRWSG) that was used to generate the VE1 antibody and regions of multiple axonemal dynein heavy chain proteins (eg, DNAH2, DNAH7, and DNAH12). These proteins are major components of the axonemes of cilia and flagella where they drive the sliding of microtubules. In ELISA assays, we show that the VE1 antibody recognizes epitopes from these proteins. A familiarity with the cross-reactivity of the VE1 antibody with epitopes of proteins in cilia is of value when evaluating tissues stained with this important clinical antibody.

Abstract
Craniopharyngioma is one of the most common non-glial intracranial tumors of childhood. Its relation to Rathke's cleft cyst (RCC) is controversial, and both lesions have been hypothesized to lie on a continuum of cystic ectodermal lesions of the sellar region. The authors report on a 7-year-old boy who presented with decreased visual acuity, presumably of at least 2 years' duration, and was found to have a 5.2-cm sellar lesion with rim enhancement. Histological examination of the resected lesion showed a mixture of areas with simple RCC morphology with focal squamous metaplasia and areas with typical craniopharyngioma morphology. Immunohistochemical staining with CK20 and Ki 67 differentially highlighted the 2 morphological components. Testing for beta-catenin and BRAF mutations was negative in the craniopharyngioma component, precluding definitive molecular classification. Follow-up imaging showed minimal residual enhancement and the patient will be closely followed up with serial MRI. Given the clinical and histological findings in the case, a progressive transformation of the RCC to craniopharyngioma seems to be the most plausible explanation for the co-occurrence of the 2 lesion types in this patient. An extensive review of previously proposed theories of the relationship between craniopharyngioma and RCC is also presented.

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
A 73-year-old woman admitted to our hospital because of headache, poor appetite, malaise, weight loss, and vomiting was found to have central adrenal insufficiency and thyrotoxicosis due to silent thyroiditis. Polyuria developed after replacement with glucocorticoid (masked diabetes insipidus), which was controlled with nasal administration of desmopressin. Magnetic resonance imaging of the brain showed a large cystic pituitary mass (18 × 18 × 12 mm) extending suprasellarly to the optic chiasm. Transsphenoidal surgery revealed that the pituitary tumor was Rathke's cleft cyst. Following surgery, replacement with neither glucocorticoid nor desmopressin was needed any more. Therefore, it is suggested that Rathke's cleft cyst is responsible for the masked diabetes insipidus and the central insufficiency. Furthermore, it is speculated that thyrotoxicosis with painless thyroiditis might induce changes from subclinical adrenal insufficiency to transiently overt insufficiency.

Abstract
Expression of the platelet-derived growth factor A-chain gene (Pdgfa) occurs widely in the developing mouse, where it is mainly localized to various epithelial and neuronal structures. Until now, in situ mRNA hybridization (ISH) has been the only reliable method to identify Pdgfa expression in tissue sections or whole mount preparations. Validated protocols for in situ detection of PDGF-A protein by immunohistochemistry is lacking. In particular, this has hampered understanding of Pdgfa expression pattern in adult tissues, where ISH is technically challenging. Here, we report a gene targeted mouse Pdgfa allele, Pdgfaex4COIN, which is a combined conditional knockout and reporter allele. Cre-mediated inversion of the COIN cassette inactivates Pdgfa coding while simultaneously activating a beta-galactosidase (lacZ) reporter under endogenous Pdgfa transcription control. The generated Pdgfaex4COIN-INV-lacZ allele can next be used to identify cells carrying a Pdgfa null allele, as well as to map endogenous Pdgfa expression. We evaluated the Pdgfaex4COIN-INV-lacZ allele as a reporter for endogenous Pdgfa expression patterns in mouse embryos and adults. We conclude that the expression pattern of Pdgfaex4COIN-INV-lacZ recapitulates known expression patterns of Pdgfa. We also report on novel embryonic and adult Pdgfa expression patterns in the mouse and discuss their implications for Pdgfa physiology.
