Intrasellar Gangliocytoma Resembling Pituitary Adenoma

Abstract

Cushing's disease resulting from intrasellar gangliocytomas is very rare and only three cases have been reported to date. All of the cases were female. We present a fourth case of Cushing's disease resulting from intrasellar gangliocytoma. Computed tomography and magnetic resonance imaging scans showed a pituitary macrotumorwith suprasellar extension. A greenish-gray colored homogenous tumor was subtotally removed by a transcranial approach. Histological diagnosis was gangliocytoma. To the best of our knowledge, this is the first reported instance of a tumor causing Cushing's disease in a man in the absence of a pituitary adenoma component.
