Objectives Rathke's cleft cysts (RCC) are benign cystic lesions of the sella resulting from incomplete obliteration of Rathke's cleft. Symptomatic lesions often require surgical decompression, which is often amenable to a transnasal, transsphenoidal (TNTS) approach. We report our experience with marsupialization of RCC and describe a novel technique to promote re-epithelization of the cyst cavity. Design Retrospective review. Setting Tertiary academic medical center. Participants Patients who underwent TNTS for RCC between 2007 and 2015...

The sellar xanthogranuloma is a rare lesion of the sellar-parasellar region difficult to differentiate from other tumors such as craniopharyngiomas or Rathke's cleft cyst in the preoperative evaluation. As they are recently recognized as a separate entity and the few number of reports in the literature, its etiology is unknown and its impact remains uncertain. This article will describe the first three cases reported in Latin America, identified in one of them an imaging feature that may be helpful to elucidate an imaging growth pattern...

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...

Xanthomatous lesions of the sellar region have traditionally been divided into two separate categories, xanthomatous hypophysitis (XH) and xanthogranuloma (XG) of the sellar region. The seminal paper on XH, a condition typified by foamy histiocytes and lymphoplasmacytic infiltrates in the pituitary gland/sellar region, but usually little or no hemosiderin pigment, detailed 3 patients. However, most reports since that time have been single cases, making understanding of the entity difficult. In contrast, the seminal report on XG, characterized by sellar region cholesterol clefts, lymphoplasmacytic infiltrates, marked hemosiderin deposits, fibrosis, multinucleated giant cells around cholesterol clefts, eosinophilic granular necrotic debris, and accumulation of macrophages, included 37 patients, allowing more insights into etiology...

Male germ cell differentiation proceeds to a large extent in the absence of active gene transcription. In Drosophila, hundreds of genes whose proteins are required during post-meiotic spermatid differentiation (spermiogenesis) are transcribed in primary spermatocytes. Transcription of these genes depends on the sequential action of the testis meiotic arrest complex (tMAC), Mediator complex, and testis-specific TFIID (tTFIID) complex. How the action of these protein complexes is coordinated and which other factors are involved in the regulation of transcription in spermatocytes is not well understood...

Xanthomatous hypophysitis is a rare inflammatory disease of the pituitary gland that can mimic a neoplastic lesion clinically and radiologically. Its pathogenesis remains largely unknown, although recent evidence suggests that pituitary inflammation may occur as a secondary reaction to mucous content released from a ruptured cyst. In a series of 1221 pituitary specimens, we identified seven cases of xanthomatous hypophysitis. Six patients had complete radiological and biochemical workup preoperatively: a cystic-appearing pituitary mass was identified in all six patients (100%) with a mean size of 2...

OBJECTIVES: To determine the risk factors associated with cerebrospinal fluid (CSF) leak following endoscopic endonasal surgery (EES) for pediatric skull base lesions. METHODS: Retrospective chart review of pediatric patients (ages 1 month to 18 years) treated for skull base lesions with EES from 1999 to 2014. Five pathologies were reviewed: craniopharyngioma, clival chordoma, pituitary adenoma, pituitary carcinoma, and Rathke's cleft cyst. Fisher's exact tests were used to evaluate the different factors to determine which had a statistically higher risk of leading to a post-operative CSF leak...

The case report describes a teratoma of the sellar region with a gland forming and an immature, relatively clear undifferentiated component without signs of anaplasia. Both components express TTF-1 indicating their presumable origin in the neurohypophysis as part of the circumventricular organs. The differential diagnosis includes pituitary adenoma and spindle cell oncocytoma with inclusion of Rathke's cleft cyst, pituitary blastoma, yolk sac tumor, and other germ cell tumors. The prognosis is the same as in the immature teratomas in the gonads, specifically unclear...

PURPOSE: Rathke cleft cysts (RCC) usually are asymptomatic and can be observed via the use of conservative methods. Some patients with RCCs, however, have severe headaches even if they are small enough to be confined to the sella, and these small RCCs seldom have been discussed. This study presents an investigation into clinical characteristics of small RCCs associated with severe headaches, demonstrating efficacy and safety of endoscopic transsphenoidal surgery (ETSS) to relieve headaches...

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.

Sphaeromatid isopods, such as Dynamene, are common and abundant members of the invertebrate fauna of littoral and shallow sublittoral substrates. Six species of Dynamene occur in the northern hemisphere. Only two species exist outside this range, in Australia. The distribution of the various species in the NE Atlantic-Black Sea axis has been controversial due to the difficulty in the identification of the different species. This has led to inaccurate records of their distribution, ultimately generating uncertain or faulty assessments on the biodiversity of these habitats...

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...

BACKGROUND: A Rathke cleft cyst (RCC) with nonhemorrhagic rupture mimicking pituitary apoplexy has been reported rarely. 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 hyperintensity in the cerebral cisterns, whereas 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...
