title: Astrocytoma of the pituitary gland (pituicytoma): case report.
abstract: A 34-year-old man presented with a 4-month history of visual obscuration. Magnetic resonance imaging showed a solid, discrete, contrast-enhancing pituitary mass with suprasellar extension. Surgery, which was performed via a transsphenoidal approach, disclosed the pituitary tumor to be a fibrillary astrocytoma (pituicytoma). This case report contains the clinical and neuroimaging features of this rare tumor of the neurohypophysis, which masqueraded as a pituitary adenoma.
