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

Abstract
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.

World Neurosurg 2016; 98:882.e15-882.e20. [PMID: 27769949 DOI: 10.1016/j.wneu.2016.10.052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Revised: 10/06/2016] [Accepted: 10/09/2016] [Indexed: 10/20/2022]
Abstract
BACKGROUND In Rathke cleft cysts (RCCs), inflammation by the cyst contents infrequently spreads to the surrounding structures. Calcification, which is regarded as a result of chronic inflammation of the cyst wall, can rarely be found in RCCs. Moreover, ossification is extremely rare. CASE DESCRIPTION A 60-year-old woman experienced headaches, fatigue, and weight loss owing to pan-hypopituitarism. Magnetic resonance imaging revealed a mass lesion in the sellar region, which was composed of two different parts, with hypointensity anteriorly and hyperintensity posteriorly on T1-weighted image, and the rim with significant hypointensity entirely on T2-weighted image. During the transsphenoidal surgery, the cyst wall was so rigid that it was difficult to cut and remove it. The cyst contained mucinous fluid with both old and new hemorrhages, and a yellowish, elastic hard, solid nodule. Postoperative histologic diagnosis was RCC with unusual lymphocyte infiltration, massive granulation, and mature bone formation. Six months later, the fluid in the cyst reaccumulated, and the patient complained of headaches. Removal of the entire cyst wall and the aspiration of the cyst content were performed to collapse the cyst cavity and, consequently, to prevent further recurrence. Postoperatively, panhypopituitarism was unchanged and the symptoms were treated with hormonal replacement. The cyst has not recurred for 2 years after the second surgery. CONCLUSIONS Persistent, long-term inflammation induced by the RCC content, mucin-containing fluid, and several phases of hemorrhage presumably promoted the formation of mature bone on the cyst wall and of the elastically solid nodule within the cyst.

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.

Spontaneous Involution of a Presumably Rathke's Cleft Cyst in a Patient with Slight Subclinical Hypopituitarism: A Case Report and Review of the Literature. Case Rep Surg 2015; 2015:971364.

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
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
We report and discuss the rare case of a pituitary abscess forming within a Rathke's cleft cyst (RCC). A 66-year-old gentleman presented with visual deterioration and symptoms suggestive of hypopituitarism. The patient underwent transsphenoidal debulking of the lesion whereupon purulent material was discovered. Histological examination was suggestive of RCC together with numerous neutrophils characteristic of abscess. Microbiological culture of the material grew Staphylococcus aureus. The patient was treated for a RCC abscess and received antibiotics and endocrine replacement therapy. The patient has been followed up for 2 years without recurrence. Although uncommon, we recommend the consideration of RCC abscess as a differential diagnosis of a pituitary mass lesion as clinical presentation and radiological assessment are not specific in identifying these lesions preoperatively.

Abstract
Rathke's cleft cyst (RCC) are benign, epithelium-lined sellar and suprasellar cysts believed to originate from remnants of the Rathke pouch. Here, we report a rare case of entirely suprasellar RCC in a 4.5-year-old child causing hypopituitarism, who presented to us with bilateral cryptorchidism. Subsequently we discuss the distinct rarity of entirely suprasellar RCC presenting in this fashion and the relevant literature is also discussed.

Abstract
BACKGROUND Claudins are tight junction proteins expressed in epithelial tissues that play important roles in cell polarity and adhesion. Altered distribution of claudin-1(CLDN1) affects cell mobility and tumor invasiveness. Craniopharyngiomas (CPs) represent epithelial tumors of the sellar region, consisting of adamantinomatous (adaCP) and papillary (papCP) variants. Their tendency to infiltrate surrounding brain structures complicates successful surgery. Reliable markers are required to predict tumor behavior and to establish individualized treatment protocols. METHODS We describe the distribution pattern of CLDN1 in a large cohort of 66 adaCPs, 21 papCPs, and 24 Rathke`s cleft cyst (RCC) cases using immunohistochemistry. CLDN1 mRNA levels were analyzed with qRT-PCR in 33 CP samples. The impact on the migration potential was studied in primary adaCP cell cultures (n = 11) treated with small interfering RNA (siRNA) for CLDN1. Furthermore, CLDN1 distribution patterns and expression levels were compared between invasive (n = 16) and noninvasive (n = 17) tumor groups. RESULTS PapCPs and RCCs exhibited a distinct homogenous and membranous expression pattern, whereas CLDN1 immunoreactivity appeared weaker and more heterogeneous in adaCPs. In the latter cases, whirl-like cell clusters showed complete absence of CLDN1. mRNA analysis confirmed reduced CLDN1 levels in adaCPs versus papCPs. Interestingly, invasive tumors exhibited significantly lower CLDN1 expression compared with noninvasive counterparts regardless of CP subtype. Accordingly, siRNA treatment for CLDN1 altered tumor cell migration in vitro. CONCLUSION CLDN1 represents a novel marker in the differential diagnosis of CP variants and RCCs. Low CLDN1 expression levels correlate with an invasive CP growth pattern and may serve as a prognostic marker.

Abstract
Rathke's cleft cysts (RCC) are cystic sellar and suprasellar lesions derived from remnants of Rathke's pouch, lined by cuboidal or columnar epithelium. RCC are usually asymptomatic but can present with headache, visual impairment, panhypopituitarism and hypothalamic dysfunction. Diabetes Insipidus as a presenting symptom of RCC is reported, but rare. We present a case of a 48-year-old male presenting with polyuria and on investigations found to have central diabetes insipidus due to a sellar RCC. Patient underwent transsphenoidal surgery with complete excision with resolution of his symptoms. His polyuria resolved post-surgery without vasopressin replacement, which has never been reported.

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
Rathke's cleft cysts (RCCs) are benign epithelium-lined intrasellar cysts containing mucoid material and are believed to originate from the remnants of Rathke's pouch. Most are asymptomatic but may cause symptoms secondary to compression of adjacent structures such as visual disturbances and endocrinopathies, especially hypopituitary. Furthermore, inflammation such as an aseptic meningitis syndrome may be associated with these tumors, presumably resulting from leakage of cyst material into the subarachnoid space. We present a unique case of spontaneous rupture and complete disappearance of a known sella-suprasellar cyst associated with a severe headache syndrome, followed by cyst reaccumulation requiring surgery. Although this phenomenon is well accepted, to our knowledge, this is the first report of the complete disappearance of a Rathke's cyst presenting with the classic syndrome. Furthermore, it was remarkable how quickly it recurred and became symptomatic, providing evidence that an “empty sella syndrome” may indeed need clinical follow-up.

Abstract
AIMS To determine the differential magnetic resonance imaging (MRI) features of pituitary adenoma, craniopharyngioma, and Rathke cleft cyst involving both intrasellar and suprasellar regions. MATERIALS AND METHODS The MRI images of 64 patients with pituitary adenoma (n=38), craniopharyngioma (n=13), or Rathke cleft cyst (n=13) were retrospectively reviewed by three neuroradiologists. The following characteristics were evaluated: shape, volume, extent, component characteristics, signal intensities of solid portions on T2-weighted images, signal intensities of cystic portions on T1-weighted images, and enhancement patterns of solid portions and cyst walls of tumours. Fisher's exact test applied with Bonferroni correction was used for multiple comparison. A flowchart for differential diagnosis was constructed based on statistical analysis of the results. RESULTS A snowman shape, solid characteristics, and homogeneous enhancement of the solid portion were more common in pituitary adenomas (p<0.017). A superiorly lobulated shape, third ventricle compression by superior tumour extension, mixed solid and cystic characteristics, and reticular enhancement of the solid portion were more common in craniopharyngiomas (p<0.017). Finally, an ovoid shape, a small tumour volume, cystic characteristics, and no or thin cyst wall enhancement were more common in Rathke cleft cysts (p<0.017). The flowchart yielded diagnostic accuracies as follows: 92.1% in pituitary adenoma; 92.3% in craniopharyngioma; 92.3% in Rathke cleft cyst; and 92.2% overall. CONCLUSION A combination of MRI findings is helpful in the differential diagnosis of the three tumours involving both intrasellar and suprasellar regions.

Abstract
A 62-year-old woman presented with general malaise persisting for 2 months and narrowing of her visual field. T1-weighted magnetic resonance (MR) imaging showed swelling of the pituitary gland and stalk, and a homogeneous isointense intra- and suprasellar mass enhanced by gadolinium. During outpatient follow up, her condition deteriorated rapidly and she developed diabetes insipidus and panhypopituitarism. T1-weighted MR imaging demonstrated shrinkage of the lesion and disappearance of the central hypointense area indicating the cyst cavity, especially in the pituitary stalk. She underwent surgical exploration via the transsphenoidal approach under a provisional diagnosis of lymphocytic hypophysitis. Histological examination revealed ciliated columnar cells and squamous metaplasia on the inner surface of the cyst wall, with many foamy cells, infiltration by many lymphoid cells and some eosinophils, and fibrosis in the adenohypophysitis and inflammatory hypophysitis in the anterior and posterior pituitary gland. The present neuroimaging findings of cyst shrinkage associated with rapid clinical deterioration strongly support the suggestion that rupture of Rathke's cleft cyst causes inflammatory hypophysitis.

Abstract
OBJECTIVE In this study, the usefulness of the transsphenoidal endoscopic approach in the treatment of a Rathke's cleft cyst is reported. METHODS Between June 1998 and December 2002, 22 patients affected by sellar-suprasellar Rathke's cleft cysts were treated using a transsphenoidal endoscopic approach. Fourteen patients experienced pituitary dysfunction (64%), five experienced visual impairment (23%), and three reported headaches (14%). RESULTS The patient follow-up ranged from 8 to 60 months (mean, 33 mo). Pituitary function was restored only in the four patients with hyperprolactinemia, whereas visual impairment and headache improved in all patients. However, when present before surgery, hypopituitarism was unaffected by surgery. Two patients experienced permanent diabetes insipidus (one of them before surgery). Only one recurrence was observed in a 13-year-old girl at 12 months after surgery, and it was treated using a new transsphenoidal endoscopic approach. CONCLUSION The transsphenoidal endoscopic approach represents a straightforward and mini-invasive approach for the drainage and biopsy of a Rathke's cleft cyst.

Abstract
OBJECT Rathke cleft cysts (RCCs) are rarely symptomatic. The purpose of this study was to clarify the clinical, neuroimaging, surgical, and pathological features of symptomatic RCCs with special attention to their recurrence. METHODS This retrospective study involved 53 patients with pathologically confirmed symptomatic RCCs. There were 28 female and 25 male patients, ranging in age from 11 to 68 years (mean 37 years). Common clinical presentations included headache, visual impairment, and endocrine disturbance. The most common endocrine disturbances were hyperprolactinemia and diabetes insipidus. Most of these improved or were resolved after surgery, with the exception of diabetes insipidus and panhypopituitarism. The cysts were intrasellar with suprasellar extension in 33 patients, and ranged in size from 5 to 40 mm (mean 17 mm). In the 50 magnetic resonance (MR) images that were reviewed, the signal intensities were quite variable. Fourteen MR images demonstrated enhancement after an injection of Gd. Intraoperatively, the cyst contents were found to be yellowish (18 patients [37%]) and mucoid (25 patients [51%]). Pathological examinations revealed a pseudostratified columnar epithelium in 26 patients (49%). Abundant squamous metaplasia and a stratified squamous epithelium were also found in 12 patients (23%). Follow-up MR images revealed cyst recurrences that required a repeated operation in six patients. Statistically significant risk factors for a recurrence included enhancement of the lesion on MR images (p = 0.017), the extent of cyst removal (p = 0.012), and the presence of squamous epithelium (p = 0.008). CONCLUSIONS Rathke cleft cysts are associated with a variety of clinical presentations and sometimes confusing intraoperative and pathological findings. Close postoperative observation with neuroimaging and neuroophthalmological assessment is necessary, especially after a partial removal, as in cases with squamous metaplasia.

Abstract
Abstract
Background.—Craniopharyngiomas are epithelial neoplasms usually located in the sellar and suprasellar regions. Distinguishing craniopharyngioma from Rathke cleft cyst is sometimes difficult, and the distinction is clinically significant because Rathke cleft cysts have a better prognosis than craniopharyngiomas.
Design.—We retrieved 10 cases with a primary diagnosis of craniopharyngioma and 5 cases with a diagnosis of Rathke cleft cyst for analysis. Five cases of normal pars intermedia of pituitary glands from autopsy served as controls. We evaluated the expression patterns of a broad range of low– to intermediate–molecular weight cytokeratins (CK7, CK8, CK10, CK17, CK18, CK19, and CK20) and high–molecular weight cytokeratins (K903: a combination of CK1, CK5, CK10, and CK14; and CK5/6) in these cases.
Results.—Craniopharyngiomas had a cytokeratin expression pattern distinct from that of Rathke cleft cysts and pituitary gland pars intermedia: craniopharyngiomas did not express cytokeratins 8 and 20, whereas Rathke cleft cysts and pars intermedia of pituitary glands both expressed cytokeratins 8 and 20.
Conclusion.—The differential expression of cytokeratins distinguishes between craniopharyngioma and Rathke cleft cyst, and this difference could be useful for identifying craniopharyngioma in difficult cases in which only a small biopsy is available. The different cytokeratin profiles of craniopharyngioma and Rathke cleft cyst suggest that these lesions do not come from the same origin, or that they come from a different developmental stage of the pouch epithelium.

Abstract
OBJECTIVE To highlight diagnostic and therapeutic issues about Rathke cleft cysts for otorhinolaryngologists. STUDY DESIGN Retrospective. METHODS We retrospectively reviewed data collected on Rathke cleft cysts between 1978 and 1998: presenting symptoms, visual acuity, surgical treatment, complications, recurrences, and effect on daily activity. RESULTS Twenty-nine patients were diagnosed with a Rathke cleft cyst (11 male and 18 female patients; mean age, 46 y). The most common presenting symptom was head pain (55%). The majority (59%) of cases demonstrated suprasellar extension on preoperative imaging, with pituitary dysfunction identified in 66%. Recurrence occurred in eight patients (28%). Postoperative visual function improved or remained stable in all patients. Persistent pituitary dysfunction required hormonal supplementation in seven patients (24%). Only one patient with an astrocytoma in addition to a Rathke cleft cyst did not maintain the ability to perform normally on an assessment of activities of daily living, a striking contrast to patients with craniopharyngioma. CONCLUSIONS Conclusions were as follows: 1) Rathke cleft cysts must be considered as sources of head pain and pituitary dysfunction. 2) Persistent or recurrent cyst formation occurs in approximately one-third of the patients. Recurrence may take many years, and follow-up imaging is recommended for at least a decade. 3) Maintenance of the ability to perform the activities of normal daily living can be expected after surgical management. 4) Most Rathke cleft cysts can be managed through transnasal exposure of the sella. 5) Packing the sella may result in predisposition to recurrent cyst formation.

Abstract
A 46-year-old Japanese male was admitted for the evaluation of severe hypertension. He was obese and had a eunuchoidal body habitus. Chromosomal analysis revealed a 46, XY/47, XXY karyotype. Serum LH, FSH and testosterone levels were low, indicating hypogonadotropic hypogonadism. Endocrinological dynamic tests disclosed presence of hypothalamic panhypopituitarism, partial diabetes insipidus, type 2 diabetes mellitus and low renin essential hypertension. Brain computed tomography and magnetic resonance imaging revealed intra- and extrasellar masses. Histological examination of the tissue obtained at transsphenoidal surgery showed a Rathke's cleft cyst (RCC). To the best of our knowledge, this is the first case report of mosaic Klinefelter's syndrome accompanied by symptomatic RCC, type 2 diabetes mellitus and low renin essential hypertension.

Abstract
Rathke's cleft cysts usually present with an intrasellar or a combined intrasellar and suprasellar localization. In this report we present a 58-year-old man with a Rathke's cleft cysts in an entirely suprasellar location with intact diaphragm and intact sella. Although this presentation of a Rathke's cleft cyst is extremely rare, it belongs in the differential diagnosis of entirely suprasellar lesions. The relevant literature is discussed.

Abstract
Rathke's Cleft Cyst (RCC), which is located at the intrasellar region, is considered to be the distended remnants of Rathke's pouch, an invagination of the stomodeum. Lined with columnar or cuboidal epithelium of ectodermal origin, RCC usually contains mucoid material and it is found in 13-22% of normal pituitary glands. The cyst rarely leads to the development of symptoms but, when it does, the most common presenting symptoms are headache, visual impairment, hypopituitarism and hypothalamic dysfunction. However, in some cases it presents symptoms of diabetes insipidus, decreased libido and impotence. Recently we experienced a case of RCC inflammation presenting with diabetes insipidus and treated with transsphenoidal surgery. To our knowledge, this is the first report of RCC presenting with symptoms of diabetes insipidus in Korea.

Abstract
We studied retrospectively a series of four patients with Rathke pouch cysts and pointed out to their clinical presentation and treatment. They all occurred with female patients. Predominant symptoms were amenorrhea, headache and visual disorders. We present a revision of the literature concerning various series of Rathke's pouch cysts. We conclude that surgery is the best therapeutical procedure and transsphenoidal approach is the best surgical technique.

Rathke's cleft cysts are developmental abnormalities of the craniopharyngeal duct composed of retained stratified ciliated cuboidal cells of the respiratory type. Incidentally found in the pars intermedia in 13% to 33% of routine autopsies, they are discovered in growing numbers on CT and MRI scans. From 1991 to 1999, 9 cases of Rathke's cleft cysts were encountered by the senior authors, 4 of which were treated surgically (3 by using a transsphenoidal approach and one by using a transcranial subfrontal approach). Of the 3 patients treated with a transsphenoidal approach, 2 presented with symptoms mimicking sphenoid sinusitis and were initially referred for otolaryngologic evaluation. The clinical, pathologic, and radiologic features, as well as management and follow-up of those 2 patients, are reviewed. There has been only one previous case report of Rathke's cleft cysts presenting as sinusitis. Nevertheless, the otolaryngologist should be aware of this condition because it may present with other significant symptomatic extracranial extensions.

Abstract
Two unusual cases of pituitary cysts are described. Both patients presented with sudden onset of severe headache, and magnetic resonance imaging (MRI) demonstrated pituitary cysts, which regressed over months. Although the precise etiology of the cysts was unproven, the cystic lesions in our patients are thought to have shrunken after "pituitary apoplexy."

Abstract
The distinction among craniopharyngioma (CR), Rathke's cleft cyst (RCC), and intrasellar arachnoid cyst (AC) remains a difficult preoperative problem. Accurate diagnosis of these rare pituitary lesions is important to determine the type of treatment and predict prognostic outcome. The majority of the literature describes the clinical manifestations and management of only one of CR, RCC, or AC, rendering comparisons difficult. We conducted a study to 1) investigate distinguishing preoperative clinical, biochemical, and radiographic features of patients with CR, RCC, and AC; and 2) identify clinicopathological features that independently predict recurrence in CR and RCC in adults. Fifty-two adult patients included 21 patients with CR (mean age at initial surgery, 35 +/- 14 yr), 26 patients with RCC (mean age, 37 +/- 14 yr), and 5 patients with AC (mean age, 53 +/- 12 yr). Mean follow-up duration was 70 +/- 13 months. Patients with CR presented with hypopituitarism in 95% of cases and hyperprolactinemia in 38%. These patients also had more preoperative neurological deficits (67%), ophthalmological complaints (67%), and significantly higher psychiatric manifestations (33%; P = 0.003) than those with RCC or AC. Patients with AC presented with headaches (60%), visual field deficits (60%), or impotence (50%) in the absence of other specific endocrine dysfunction symptoms. Using biochemical criteria, the percentage of patients with two or more pituitary hormonal axes impaired preoperatively was 67% for CR and 62% for RCC, significantly greater (P = 0.03) than that for the AC patients who had pituitary dysfunction of only one axis. The composition of CR lesions was cystic (38%), solid (10%), or mixed solid and cystic (43%). Patients with RCC or AC groups had a significantly greater proportion (P = 0.006) of purely cystic lesions (88% and 100%, respectively). Calcification detectable on computed tomographic scanning was present in 87% of patients with CR, a significantly greater proportion (P < 0.001) compared to those with RCC (13%) or AC (0%). No significant differences were found between the groups based on computed tomography density, the presence of postcontrast enhancement, or magnetic resonance imaging. Recurrence rate was 62% for CR, 19% for RCC, and 20% for AC. Surgical intervention statistically improved most neurological, ophthalmological, and psychiatric manifestations; in contrast, galactorrhea, menstrual dysfunction, and diabetes insipidus (52% CR; 31% RCC) did not improve or became worse postoperatively. A significantly higher percentage of patients with CR required postoperative hormone replacement. Similarly, there was a biochemical trend suggesting that a smaller proportion of patients with CR improved in at least one pituitary axis after surgery (P = 0.08) compared to those with RCC or AC. There was a positive correlation between cyst size and recurrence rate (r = 0.689; P < 0.01) and between cyst size and time to recurrence (r = 0.582; P = 0.037) for all three groups. We describe the largest clinical, biochemical, radiographic, and histological series of adult patients with cystic disease of the sella turcica. Patients with AC tended to be older at initial diagnosis than CR or RCC patients. Mass effects, such as visual problems and headaches, are common symptoms of all three cystic lesions, but psychiatric deficits favor a diagnosis of CR. Calcification or solid components on neuroimaging characterize CR. Endocrinological deficits, especially diabetes insipidus, had the worst prognosis after surgery. Low recurrence rates can be expected for RCC and AC. These data have direct implications for the management and monitoring of patients with cystic lesions of the sella turcica.

Abstract
Rathke's cleft cysts are sometimes associated with aseptic meningitis or metabolic encephalopathy due to hyponatremia. We treated such a case manifest by lethargy, fever and electroencephalographic abnormalities. A 68-year-old man was admitted to our ward after experiencing general malaise, nausea and vomiting and then high fever and lethargy. On admission, he was drowsy and had nuchal rigidity and Kernig's sign. Physically, he was pale with dry, thickened skin. He had lost 5.0 kg of body weight in the last month. His serum sodium was 115 mEq/l. He had a low serum osmotic pressure (235 mOsmol/l) and a high urine osmotic pressure (520 mOsmol/l). His urine volume was 1200-1900 ml/24 h with a specific gravity of 1008-1015. The urine sodium was 210 mEq/l. He did not have an elevated level of antidiuretic hormone. Electroencephalograms showed periodic delta waves over a background of theta waves. With sodium replacement, the patient become alert and symptom free, and his electroencephalographic findings normalized. However, the serum sodium level did not stabilize, sometimes falling with a recurrence of symptoms. Magnetic resonance imaging clearly delineated a dumbbell-shaped intrasellar and suprasellar cyst. The suprasellar component subsequently shrunk spontaneously and finally disappeared. An endocrinologic evaluation showed panhypopituitarism. The patient was given glucocorticoid and thyroxine replacement therapy, which stabilized his serum sodium level and permanently relieved his symptoms. A transsphenoidal approach was performed. A greenish cyst was punctured, and a yellow fluid was aspirated. The cyst proved to be simple or cubic stratified epithelium, and a diagnosis of Rathke's cleft cyst was made. The patient was discharged in good condition with a continuation of hormonal therapy. Rathke's cleft cyst can cause aseptic meningitis if the cyst ruptures and its contents spill into the subarachnoid space. Metabolic encephalopathy induced by hyponatremia due to salt wasting also can occur if the lesion injures the hypothalamus and pituitary gland.

Abstract
PURPOSE At least one type of Rathke cleft cyst has unique MR findings, specifically, high intensity on T1-weighted images and iso- to low intensity on T2-weighted images relative to white matter. To clarify the influence of cyst content on MR images, we analyzed the cyst content by biomedical methods after surgical removal. METHOD We studied five patients diagnosed with Rathke cleft cyst, whose MR images showed high intensity on T1-weighted images and iso- to low intensity on T2-weighted images. After surgery, total protein and cholesterol levels were quantified, and correlations of protein and cholesterol content with T1 and T2 signal intensities were performed in vitro. RESULTS All five cysts had very high concentrations of protein (11,700-26,600 mg/dl, mean 17,940 mg/dl) with nearly no cholesterol (at most 2.0 mg/dl). Along with increases in protein concentration in vitro, the signal intensity of T1-weighted images increased, while that of T2-weighted images decreased. In contrast, the cholesterol concentration sequence influenced the signal intensity of neither T1- nor T2-weighted images. CONCLUSION The unique MR finding of Rathke cleft cysts--high signal intensity on T1-weighted images and low signal intensity on T2-weighted images--might depend mainly on protein concentration, not on cholesterol.

Abstract
OBJECTIVE This is a retrospective study of a series of 28 Rathke's cleft cysts operated on transsphenoidally that was undertaken for the following reasons: 1) to study the presentation, with particular reference to hormonal and visual disturbances; 2) to study postoperative improvements in endocrine function and vision; 3) to record postoperative complications; and 4) to assess the efficacy of a minor modification of the standard transsphenoidal surgical technique, whereby the cyst is allowed to drain directly into the sphenoid air sinus without fossa floor repair when there is no intraoperative cerebrospinal fluid leak. METHODS A retrospective study was made of case notes, radiological findings, and operative notes in the series. RESULTS There were 16 female and 12 male patients, with a mean age of 45 years. Endocrine disturbance was the most common presentation (50%), followed by headaches (32.1%) and visual impairment (14.3%). Neuroophthalmological assessment showed central visual acuity and field deficits in 32.1 and 44.6% of eyes, respectively. Biochemically, 85.7% of patients showed hormonal disturbances. Magnetic resonance imaging was used for 84.7% of cases, and 60.7% of cases showed suprasellar extension. Four magnetic resonance imaging patterns were noted. All cases were operated on transsphenoidally. Postoperative complications included cerebrospinal fluid rhinorrhea (7.1%), diabetes insipidus (3.6%), and meningitis (3.6%). Recovery of visual acuity and field was seen in 66.6 and 68% of eyes, respectively. Postoperative prolactin levels declined to normal or nearly normal values in 62.5% of cases, 20% of cases with low preoperative gonadotrophin levels achieved normal levels, and 15.4% of cases with preoperative pan-hypopituitarism achieved normal serum cortisol levels postoperatively. Within the study period there were no recurrences; although a relatively short time interval is presented for this series, a patient with a similar lesion operated on by the same method 7 years previously remains well, without radiological evidence of recurrence. CONCLUSION Although comparatively rare and benign lesions, Rathke's cleft cysts are an important cause of hormonal and visual disturbances. Transsphenoidal surgery is safe and efficacious and leads to excellent improvement of function in the majority of cases. The surgical modification described seems safe and satisfactory and is extremely easy to perform.

Abstract
The association of large pituitary mass, lack of clinical syndromes of pituitary hypersecretion, hypopituitarism and visual field defects suggests the diagnosis of nonfunctioning pituitary adenoma, but the same characteristics can be present in patients affected by other tumorous lesions, cysts, inflammatory processes or vascular disease. The management of these patients depends on a correct diagnosis. A 53-year-old woman was admitted for nausea, vomiting and severe hypotension. For three months she had complained of weakness, sleepness, skin-dryness and loss of weight. Imaging and endocrine evaluations revealed an intra and extrasellar mass causing hypopituitarism without diabetes insipidus. Histological examination of the tissue obtained at transsphenoidal surgery showed a Rathke's cleft cyst, surrounded by areas of noncaseous granulomatous tissue with scattered multinucleated giant cells of foreign body type, similar to a sarcoid lesion. Other systemic sarcoidosis localizations were absent. After two years of full well-being, the patient reported a sudden visual impairment, due to sarcoidosis involvment of the prechiasmatic tract of the optic nerve, that promptly improved with corticosteroid treatment. This report emphasizes the overlap of signs and symptoms between non functioning tumors and nontumoral masses of hypothalamic-pituitary region and underlines the fact that a correct diagnosis is feasible only on histopathological basis. Although, occasionally, the coexistence of Rathke'cyst with pituitary adenoma has been reported, to the best of our knowledge, this is the first report of the association between Rathke's cleft cyst and noncaseating granuloma tissue. Finally, the remission of neurolgical symptoms following corticosteroid therapy confirms this treatment as a valid medical approach and suggests its use in a short therapeutic trial when the diagnosis is doubtful.

Abstract
Nocturnal enuresis is considered a benign condition partially explained by a defect circadian rhythm of vasopressin. An organic cause may be responsible for an abnormal pituitary function, when enuresis persists into adulthood. In the present study the pituitary gland and surroundings of 8 adults suffering from primary monosymptomatic nocturnal enuresis were studied by magnetic resonance imaging. The pituitary gland appeared normal in all, except from a Rathke's cleft cyst observed in one patient. This cleft cyst was not considered to be clinically important. It was concluded, that severe nocturnal enuresis persisting into adulthood is not likely to be combined with detectable pathology on magnetic resonance imaging of the pituitary gland.

Abstract
PURPOSE We studied the neuro-ophthalmic features of patients with symptomatic Rathke's cleft cysts, to distinguish features of Rathke's cleft cysts from those of craniopharyngioma. METHODS Eleven patients who had undergone surgery for symptomatic Rathke's cleft cysts in the Liverpool University Department of Neurological Science were identified from the records. Histopathologic analyses, clinical notes, and radiologic investigations were reviewed. RESULTS Eight of the 11 patients initially had visual problems. Reduced visual acuity, visual field defect, or both, were detected in nine patients. Optic atrophy was observed in eight patients. Other initial features included headaches, epilepsy, and endocrine disturbance. All patients recovered from surgery, and an improvement in the visual acuity or visual field defect was noted in six patients. CONCLUSIONS Symptomatic Rathke's cleft cysts often manifest as visual disturbance. Every effort to distinguish Rathke's cleft cysts from craniopharyngiomas should be made preoperatively. Rathke's cleft cysts only require limited surgical intervention, and radiotherapy is not necessary. Early recognition and treatment can lead to improvement in visual function.

Abstract
Cystic epithelial lesions of the sellar and parasellar region are classified on the basis of histology and location into Rathke's cleft cysts, epithelial cysts, epidermoid cysts, dermoid cysts, and craniopharyngiomas. A retrospective review of the clinical presentation, radiological findings, and histology was performed on 19 such lesions, and a survey of the literature pertinent to the classification, clinical presentation, and embryology of these lesions was conducted. Presentation was nonspecific and not predictive of histology. Imaging studies were generally useful in distinguishing these tumors, with the exception of Rathke's cleft cysts, suprasellar epidermoid cysts, and craniopharyngiomas, which frequently could not be differentiated. On microscopic examination, most lesions fit into distinct categories; however, overlap was common among all and some could not be definitively categorized by histological criteria. Evidence supportive of an ectodermal ancestry for sellar and parasellar epithelial-lined cystic lesions is presented. Based on the current findings and a review of the literature, it is suggested that these lesions represent a continuum of ectodermally derived cystic epithelial lesions.

Abstract
The craniopharyngeal duct is the route by which the adenohypophysis ascends from the pharynx to the pituitary fossa. Rathke's cleft cyst represents an expansion of primitive vesicles that lie between the pars intermedia and the pars anterior. These cysts are rare but have been detected more frequently with the more widespread use of CT and MRI. Three cases are described which illustrate the variety of positions that a cystic lesion of the craniopharyngeal duct can occupy. These cases provide a basis for the discussion of the embryological formation of the pituitary, cyst formation of the duct, and CT and MRI appearances of the cysts.

Abstract
Although Rathke's cysts are a relatively common autopsy finding, rarely have they been reported as a clinical entity. Because of recent improvements in neuroradiological imaging, cystic intrasellar and suprasellar lesions are discovered often, leading to questions about proper management. Against this background, we reviewed the data from 43 patients with Rathke's cysts treated by one neurosurgeon over a 13-year period, and present the results here. The 43 patients had a mean age of 34 years, and 77% were female. Headache was the most common symptom, followed by galactorrhea, visual field loss, and hypopituitarism. Computed tomographic (CT) scans were reviewed in 20 cases, magnetic resonance (MR) images were reviewed in 15, and both CT and MR studies were reviewed in 5 cases. Although all Rathke's cysts were discrete and well-defined by both CT and MR imaging, the diversity of locations, CT attenuations, and MR signal intensity make it difficult to establish the diagnosis by radiological criteria. Forty patients underwent transsphenoidal surgery and three underwent craniotomy. There was one recurrence at 25 months requiring a second operation, and the mean follow-up period was 62 months. Seven patients had persistent headaches. For symptomatic lesions suspected to be Rathke's cysts, the recommended treatment is simple drainage of the cyst with biopsy of the wall, when this can be done safely. Follow-up imaging should be minimal for asymptomatic patients, and radiation therapy is not indicated.

Abstract
The clinical, radiographic, and pathological findings in 155 patients with symptomatic Rathke's cleft cysts are discussed. Eight patients were treated by the authors and 147 were collected in a review of the literature. This lesion occurred more often in female than male patients by a 2:1 margin, and the mean age at presentation was 38 years. The average patient had been symptomatic for nearly 3 years at the time of treatment, with the most common symptoms and signs being pituitary dysfunction, visual disturbances, and headaches. Affected children generally were pituitary dwarfs. The sella was enlarged in 80% of cases, and the cyst was situated in both an intrasellar and a suprasellar location in 71%. Computerized tomography revealed a low-density cystic mass with capsular enhancement in one-half of the cases. A variable appearance was seen with magnetic resonance imaging. Partial excision and drainage of the cyst by the transsphenoidal approach is the recommended treatment, as the recurrence rate is low. Most symptoms and signs improved or resolved following surgery with the exception of hypopituitarism and diabetes insipidus. The cyst lining was usually composed of ciliated cuboidal or columnar epithelium. Theories as to the origin of Rathke's cleft cysts are also discussed.

Abstract
Nineteen epithelial cysts in the central nervous system including six colloid cysts of the third ventricle, seven Rathke's cleft cysts in the sella, two enterogenous cysts in the posterior fossa, two epithelial cysts in the spinal canal and two neuroectodermal cysts in the cerebrum were examined immunohistochemically for expression of intermediate filament proteins-simple type, stratified type and skin type cytokeratins and GFAP. Colloid cysts of the third ventricle, Rathke's cleft cysts in the sella and epithelial cysts in the spinal canal expressed complex type cytokeratins while enterogenous cysts and neuro-ectodermal cysts showed only simple type cytokeratins. In addition, Rathke's cleft cysts expressed GFAP in occasional lining cells. The characteristic composition and distribution of cytokeratins in various kinds of epithelial cysts in the central nervous system are demonstrated and discussed with regard to their origins.

Abstract
Rathke's duct is a midline structure, arising from the primitive stomodeum and extending upward to the hypophysis. The duct, which normally involutes in utero, may persist on occasion. This most frequently results in intracranial disease. Occasionally, disease may become manifest in the extracranial skull base. We present three such cases: cystic craniopharyngioma, Rathke's cleft cyst, and a persistent cerebrospinal fluid rhinorrhea caused by a patent craniopharyngeal canal. Each lesion involved the clivus and the parasphenoid region. Surgical management of such lesions requires not only extirpation of disease, but also the ability to recognize and preserve the many important regional structures. The procedure that best allows for the wide exposure necessary to accomplish these goals is the infratemporal fossa approach to the lateral skull base.
