Introduction: Rathke cleft cysts (RCC’s) are cystic sellar and supra sellar benign lesions which are thought to originate from the remnants of Rathke’s pouch. There are no specific clinical or radiological signs to differentiate them from other pituitary lesions. Presentation of Case: We report a 25-year-old female presented with hyperandrogenism and menstrual disorder, with the preliminary ...

INTRODUCTION Pituitary adenomas represent the most frequently observed type of sellar masses; however, the presence of a rapidly growing sellar tumor, diabetes insipidus, ophthalmoplegia and headaches in an older patient strongly suggests metastasis to the pituitary. Since the anterior pituitary has a great reserve capacity, metastasis to the pituitary and pituitary involvement in lymphoma are ...

Lipomatous hemangiopericytoma is a rare variant of hemangiopericytoma. Only a few cases of LHPC have been reported to date, with only two cases of this entity having been reported in the head and neck area, and none intracranially. We present the clinical, radiological, and histological features of the first reported case of a sellar lipomatous hemangiopericytoma, and review the literature. Mat...

OBJECTIVE To clarify the anatomical correlations of the sphenoid sinus with surrounding structures in the normal Korean population, and to identify surgical landmarks for safe sellar floor dissection in the anterior skull base by endoscopy and microscopy. METHODS We reviewed the 196 brain magnetic resonance imaging findings showing a normal appearance, and measured the distances between anato...

Spontaneous reossification of the sellar floor after transsphenoidal surgery has been rarely reported. Strontium ranelate, a divalent strontium salt, has been shown to increase bone formation, increasing osteoblast activity. We describe an unusual case of a young patient with Cushing's disease who was treated with strontium ranelate for low bone mass who experienced spontaneous sellar reossific...

Intrasellar arachnoidocele is a herniation of the optochiasmatic cistern through dehiscence sellar diaphragm producing an empty sella turcica, hence its name turcica syndrome. It extremely rare benign malformative pathology. We report case intra-sellar in 34-year-old woman revealed during annual control mass under dossinex by cerebral magnetic resonance imaging (MRI) which found cystic formatio...

Background: Preoperative differentiation of histologic etiology of sellar lesions is of profound clinical importance because it determines the use of surgery versus nonsurgical technique, transsphenoidal versus transcranial routes and the degree of surgical resection. Objective: We provide an overview of the most relevant magnetic resonance imaging characteristics together with clinical finding...
