OBJECTIVE To describe the clinical features of invagination of the sphenoid sinus mucosa (ISM) and compare them with other similar cases using a visual analog scale (VAS) to assess the various nasal symptoms and to discuss its clinical significance and means of prevention. STUDY DESIGN Retrospective chart review at a tertiary referral center. METHODS Between 2010 and 2015, 8 patients who ha...

INTRODUCTION We have presented a rare case of growth hormone (GH) producing pituitary adenoma with lymphocytic infiltration and brain parenchyma invasion. CASE PRESENTATION A 37-year-old woman has presented with complaints of headache, amenorrhea and acromegalic features. Her laboratory studies showed markedly elevated levels of Insulin-like Growth Factor 1 (IGF-1), and low levels of follicle...

INTRODUCTION Hemangioblastomas are rare, benign tumors occurring in any part of the nervous system. Most are found as sporadic tumors in the cerebellum or spinal cord. However, these neoplasms are also associated with von Hippel-Lindau disease. We report a rare case of a sporadic sellar hemangioblastoma that became symptomatic due to pituitary apoplexy. CASE PRESENTATION An 80-year-old, other...

background: proposing a strategy for sellar reconstruction in endoscopic transsphenoidal transsellar approach for pituitary adenoma. methods: 240 patients with pituitary adenoma underwent pure endoscopic endonasal transsphenoidal surgery. intra-operative csf leaks were classified as grade 0, no observable leak grade 1, csf dripping through an arachnoid membrane defect of less than 1 mm and grad...

Ossifying fibroma of the sellar turcica is extremely rare. There are only sporadic case reports in the literature. One such case simulating pituitary adenoma is presented in an 18-year-old girl.

Background and Importance. Sellar arachnoid cysts and Rathke's cleft cysts are benign lesions that produce similar symptoms, including optochiasmatic compression, pituitary dysfunction, and headache. Studies have reported the use of various surgical treatment methods for treating these symptoms, preventing recurrence, and minimizing operative complications. However, the postoperative cerebrospi...

The concomitant presence of three histopathologically different entities in the pituitary gland is a rare occurrence. Most publications identify at least two distinct pathologies, mainly, a pituitary adenoma coexisting with a second intrasellar lesion. We present a case of a 71-year-old female referred for evaluation and treatment of acromegaly. Questioning revealed she was experiencing facial ...

Extraventricular neurocytomas (EVN) are rare central nervous system tumors, often located within the cerebral hemisphere. The present study reports a case of a 56-year-old male patient with bitemporal hemianopsia. Computed tomography and magnetic resonance imaging revealed a tumor in the sellar region. The tumor was totally excised. Postoperative histological examination of the tumor demonstrat...
