INTRASELLAR GANGLIOCYTOMA RESEMBLING PITUITARY-ADENOMA

Gushing's disease resulting from intrasellar gangliocytomas is very ra re and only three cases have been reported to date. All of the cases w ere female. We present a fourth case of Gushing's disease resulting fr om intrasellar gangliocytoma. Computed tomography and magnetic resonan ce imaging scans showed a pituitary macrotumor with suprasellar extens ion. A greenish-gray colored homogenous tumor was subtotally removed b y a transcranial approach. Histological diagnosis was gangliocytoma. T o the best of our knowledge, this is the first reported instance of a tumor causing Gushing's disease in a man in the absence of a pituitary adenoma component.
