OBJECT Symptomatic sellar arachnoid cysts (ACs) have typically been treated via the transsphenoidal route. After sellar cyst wall fenestration, some authors have advocated cyst wall resection and increasing communication between the AC and suprasellar subarachnoid space (SAS). This study is a report of the authors' experience using a simplified approach to reinforce a defective diaphragma sella...

We report a case of tuberculum sellae meningioma with optic tract edema. Contrary to a prior report on this topic, edema along the optic tract is not only seen in craniopharyngiomas but may be seen (although rarely) in other common parasellar tumors, as in our case of a tuberculum sellae meningioma. The pathogenesis of this edema in meningioma is controversial.

The recognition of anterior or posterior displacement of the fourth ventricle on axial computed tomography (CT) has proven to be difficult because the apparent position of this structure is variable and dependent on scanning angle. In most cases direct visualization of a lesion and its relationship to normal anatomic structures allows for the correct assessment. However, in some instances it wo...

Normal high-resolution computed tomographic (CT) scans of 126 patients were reviewed to define the diameter, height of the bifurcation, and transverse position of the normal basilar artery. The mean diameter of the normal basilar artery is 3.17 mm at the level of the pons. In 92% of normal subjects, the basilar bifurcation is located in the interpeduncular cistern adjacent to the dorsum sellae ...

The present study reports the case of a patient with a vision impairment in the right eye. Head computed tomography revealed a round, hyperdense mass in the sellar and suprasellar regions. Pituitary gland magnetic resonance imaging (MRI) revealed isointensity on T1- and T2-weighted imaging. Tumor-enhanced scanning showed heterogeneous contrast enhancement. The initial diagnosis was that of meni...

Objective To describe a unique operative strategy, instead the classical pterional approach, and to analyses it safety and effectiveness for removal of anterior cranial fossa meningiomas. Method We identify 38 patients with tuberculum sellae and olphactory groove meningiomas operated between 1986 and 2013. Medical charts, operative reports, imaging studies and clinical follow-up evaluations wer...

A 20-year-old woman presented with polymenorrhea occurring every 20 days. Physical examination revealed a prominent forehead, hypertelorism, mild exophthalmos, and several scattered pigmented lesions of the skin. Histologically, there was no evidence of malignant lesions of the skin. Laboratory examination of the pituitary function revealed normal levels of luteinizing hormone, follicle-stimula...
