BACKGROUND The transsphenoidal approach for resecting pituitary tumors has classically included reconstruction of the anterior wall of the sella turcica. A variety of materials have been used in this process for the purpose of both recreating the original anatomy and preventing postoperative cerebrospinal fluid (CSF) leaks. We studied the use of an ePTFE dural substitute (GORE Preclude MVP, W.L...
A chiasm n. optici is shaped by crossed optic nerves. Approximate vertical distance of 10 mm separates chiasm from dorsum sella turca and pituitary fosse. Twenty-five percent of all cerebral tumors appear in the chiasm area and almost half of them cause damages of visual function. Major and sometimes the only symptom is progressive visual loss. This damage appears because tumor masses are huge ...
We report the cases of two Japanese children with cystic pituitary enlargement on magnetic resonance imaging (MRI) causing central diabetes insipidus (DI). In the first patient, endocrinological examination demonstrated slightly impaired growth hormone and thyroid stimulating hormone secretions, but normal responses of other anterior pituitary hormones. The second patient had normal basal level...
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. CAS...
Background Bioabsorbable plates are frequently utilized in the repair of skull base defects following transsphenoidal operations. Traumatic intracranial pseudoaneurysms are a rare complication of transsphenoidal surgery. To date, iatrogenic carotid pseudoaneurysm associated with the use of an absorbable plate has been reported once. Results A 57-year-old man with a large nonfunctional pituitary...
AIM Pituitary adenomas do not have a single factor of aggressive behavior or recurrence. The objective of this study was to determine factors influencing the prognosis in pituitary adenomas. MATERIAL AND METHODS 243 patients who were operated between January 2000 and June 2012 were included in this retrospective study. Demographic data, age at diagnosis, date of diagnosis, date of operation, ...
Idiopathic granulomatous hypophysitis (IGH) is a rare inflammatory disease of the pituitary that commonly presents with enlargement of the pituitary gland. Clinically and radiologically, IGH is a rare sellar entity easily to be misdiagnosed as a pituitary adenoma. Through such a case, we aim to present this rarity and emphasize the importance to correctly diagnose confusing pituitary lesions co...
Sellar arachnoid cysts are rare; an infected arachnoid cyst is extremely rare as only one case has been reported to date in the literature. Here, we report a patient with an infected or inflamed sellar arachnoid cyst that was successfully treated with transsphenoidal surgery (TSA). A 53-year-old female with a history of chronic sinusitis developed a headache 5 months ago, and one month before a...
The purpose of this study is to determine the anatomical features of the sphenoid sinus using computerized tomography (CT). 100 Sudanese subjects were investigated for CT sinuses; Characterization of the sphenoid sinus and seven horizontal and vertical measurements were evaluated. Onodi cell was found in 13 subjects, 10 of them were sellar and 3 were pre-sellar. Pneumatization was of the sellar...
Xanthogranuloma (XG) of the sellar region is uncommon and is difficult to diagnose based on intraoperative frozen sections. This study is a case presentation and review of the literature, highlighting the need to explore underlying diseases in order to guarantee an accurate patient diagnosis. Herein, we presented the case of a 43-year-old woman who was afflicted with xanthogranuloma of the sell...
