Unususpected meningioma in a patient with pituitary gigantism. Case report with autopsy findings.

Abstract

A unique example of a clinically unsuspected large parasellar meningioma is described in a 36-yr-old pituitary giant who had been treated initially with conventional irradiation, subsequently by surgical excision of an acidophil adenoma, and ultimately with medroxyprogesterone acetate (MPA) prior to his demise. The patient died of increased intracranial pressure resulting from a combined mass effect of the meningioma and recurrent tumor. The relationship between radiation and the development of the meningioma is discussed, as well as the fine ultrastructure of a highly functioning acidophil adenoma.
