Objective Osteochondroma (OC) is the most common benign bone neoplasm. It infrequently occurs in the cranial cavity as a calcified lesion and very rarely presents in the sellar region. The present study summarizes the knowledge about OCs of the sellar region. Methods We searched the literature search for the clinical appearance of OCs and other calcified pathologies occurring in the sellar region. Results A total of 21 English-language articles published from 1961 to 2015 documented cases of calcified lesions in the sellar region including cerebral aneurysm, chondroid chordoma, chondroma, craniopharyngioma, OC, odontome, osteoma, pituitary adenoma, pituitary stone, Rathke cleft cyst, retinoblastoma, schwannoma, and xanthogranuloma...

BACKGROUND: There have been various reports in the literature regarding the conservative management of pituitary apoplexy, pituitary incidentalomas and Rathke cleft cysts (RCCs). However, to the best of our knowledge, spontaneous involution of cystic sellar mass has rarely been reported. We report 14 cases of cystic sellar masses with spontaneous involution. METHODS: A total of 14 patients with spontaneous regression of cystic sellar masses in our hospital were included...

PURPOSE: Cholesterol granulomas in the sella are rare and can mimic the appearance of craniopharyngioma or Rathke's cleft cysts. Information regarding the clinical presentation, imaging characteristics, and clinical course of sellar cholesterol granulomas can help clinicians to differentiate these lesions from other sellar cystic lesions. METHODS: We present three cases of sellar cholesterol granulomas. A literature review was performed for all cases of sellar cholesterol granulomas with individual patient data reported...

OBJECTIVE: Few studies have investigated treatment strategies for brain tumor with a coexisting unruptured intracranial aneurysm (cUIA). The purpose of this study was to evaluate the safety and efficacy of preoperative coiling for cUIA, and subsequent brain tumor surgery. MATERIALS AND METHODS: A total of 19 patients (mean age, 55.2 years; M:F = 4:15) underwent preoperative coiling for 23 cUIAs and subsequent brain tumor surgery. Primary brain tumors were meningiomas (n = 7, 36...

BACKGROUND: A Rathke cleft cyst (RCC) with non-hemorrhagic rupture mimicking pituitary apoplexy has been rarely reported. CASE DESCRIPTION: A 52-year-old woman, previously diagnosed with asymptomatic RCC, came to us with a severe headache, along with visual dysfunction and symptoms of pituitary insufficiency. Fluid-attenuated inversion recovery magnetic resonance imaging demonstrated diffuse hyper-intensity in the cerebral cisterns, while watery clear cerebrospinal fluid was obtained by lumbar puncture...

An 51-year-old man had undergone surgery for Rathke's cleft cyst by transsphenoidal approach on October 2015. After the surgery, cerebrospinal fluid (CSF) rhinorrhea arose. Surgical treatment of CSF rhinorrhea was performed by the same approach. Ten days after reoperation, he suffered from severe headache, high fever, and nuchal rigidity. CSF findings indicated bacterial meningitis. CSF culture showed methicillin-resistant Staphylococcus lugdunensis. He received vancomycin intravenously for 19 days and recovered from the bacterial meningitis with no serious complication...

BACKGROUND: In Rathke cleft cysts (RCCs), inflammation by the cyst contents infrequently spreads to the surrounding structures. Calcification, which is regarded as a consequence of chronic inflammation of the cyst wall, can rarely be found in RCCs, and moreover, ossification is extremely rare. CLINICAL PRESENTATION: A 60-year-old woman presented with headaches, fatigue and weight loss due to panhypopituitarism. Magnetic Resonance imaging revealed a mass lesion in the sellar region, which was comprised of two different parts, with hypointensity anteriorly and hyperintensity posteriorly on T1-weighted image (WI), and the rim with significant hypointensity entirely on T2-WI...

PURPOSE OF REVIEW: Most pituitary region masses are pituitary adenomas; however, when other sellar region masses are encountered by clinicians or pathologists, the differential diagnosis can be broad. This review will focus on updates for pituitary adenomas, as well as briefly discuss some of these other entities: Rathke cleft cyst, hypophysitis, craniopharyngioma, pituicytoma, and spindle cell oncocytoma. RECENT FINDINGS: The use of new immunohistochemical (IHC) tools for assessing transcription factors, pituitary transcription factor-1, steroidogenic factor-1, and the not-yet-widely available Tpit IHC have provided insights into origin particularly of clinically silent and even hormone-negative pituitary adenomas...

Rathke cleft cysts (RCCs) are nonneoplastic lesions that are thought to be the remnants of Rathke cleft pouch. The authors report a patient presented with a headache and was diagnosed with RCC on imaging. The lesion underwent spontaneous involution. The authors suggest that patients presenting solely with a headache to be treated conservatively, because it is uncertain whether a headache is definitively associated with RCCs and because there is the possibility of spontaneous regression.

Rathke's cleft cysts (RCC) are benign cystic lesions that originate from remnants of the epithelial lining of Rathke's pouch. RCC are known rarely to occur together with a concomitant pituitary adenoma. Here, we report a patient with a pituitary adenoma arising in the same location as a previously-resected RCC, 3 years post-operatively, and review the literature of "collision" sellar lesions. Consecutive transsphenoidal operations from a single-center between 2008 and 2016 were reviewed to identify patients with pituitary adenoma arising after surgical resection of RCC, and a systematic search of the literature was also performed to identify such patient reports, as well as reports of concomitant pituitary adenoma and RCC...

Cilia are highly conserved organelles, which serve critical roles in development and physiology. Motile cilia are expressed in a limited range of tissues, where they principally regulate local extracellular fluid dynamics. In contrast, primary cilia are expressed by many vertebrate cell types during interphase, and are intimately involved in the cell cycle and signal transduction. Notably, primary cilia are essential for vertebrate hedgehog pathway activity. Improved detection of motile cilia may assist in the diagnosis of some pathologic entities such as Rathke's cleft cysts, whereas characterizing primary cilia in neoplastic tissues may implicate cilia-dependent signaling pathways as critical for tumorigenesis...

OBJECTIVE: Apart from the "common" lesions (e.g. pituitary adenomas, Rathke's cleft cysts, meningiomas and craniopharyngiomas), there is a plethora of rare tumors or tumor-mimicking lesions in the sellar and suprasellar region (SSR). Due to a lack of characteristic imaging features, there is a dilemma in distinguishing these rare lesions from the more "common" ones preoperatively. Consequently, both diagnosis and definition of surgical goals, as well as further treatment strategies continue to be challenging for all attending physicians...

OBJECT: Hypophysitis is a rare disease entity mimicking a pituitary adenoma. In spite of crucial disease involving a pituitary gland which is a main component of hormonal axis, there have been minimal researches regarding the hypophysitis. In this study, we described the constellation of the preoperative findings including clinical, radiologic, and endocrinologic features, as well as postoperative outcomes of the hypophysitis. METHODS: The authors reviewed the data retrospectively of a total of 2,814 patients who underwent microsurgery due to pituitary mass lesion (Asan Medical Center)...

The introduction of modern endoscopy in neurosurgery brought light to one of the darkest areas: the skull base. In particular, the trans-nasal route allowed skull base surgeons to visualize and dominate the entire midline skull base. We analyzed our surgical series of 199 patients that were affected by several pathologies (pituitary adenomas, clivalchordomas, craniopharyngioma, Rathke's cleft cysts, tuberculum sellaemeningiomas, and craniovertebral junction pathologies with bulbar compression) and treated each by using a 3D-HD endoscope between December 2012 and December 2015 and reviewed the literature...

The epithelial cell adhesion molecule (EpCAM) is a type I glycoprotein located on the surface of epithelial cells. It is strongly expressed in many neoplasms and already used in the diagnosis and distinction of various tumour subtypes. Comparative studies about EpCAM expression in cystic sellar lesions are lacking. Therefore, we analysed its distribution pattern in adamantinomatous (aCP) and papillary (pCP) craniopharyngiomas (CP) and Rathke's Cleft Cysts (RCC) using immunohistochemistry and gene expression profiling...

Whether a mixed type of craniopharyngioma (CP) exists and whether papillary craniopharyngioma (pCP) is on a histopathological continuum with Rathke's cleft cyst (RCC) remain controversial. Herein, we examined the expression and localization of β-catenin, BRAF p.V600E (V600E), and triggering receptor expressed on myeloid cells-1 (TREM-1) in 58 samples including 20 pCPs, 26 adamantinomatous craniopharyngiomas (aCP), and 12 RCCs. Five aCPs were diagnosed with mixed type CPs and the remaining 21 cases were pure aCPs...

INTRODUCTION: Transnasal endoscopic transphenoidal approaches are an essential technique for the resection of skull base tumors in adults. Originally devised and most commonly used to treat pituitary adenomas, they have also been used for a variety of other pathologies. However, in the pediatric population, sellar and suprasellar lesions have historically involved a craniotomy. Transnasal endoscopic transphenoidal techniques in children have only been reported as single case reports and only in regard to purely sellar lesions...

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...

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...
