Growth hormone producing pituitary adenoma and meningioma

A 59 years old woman is presented with acromegaly caused by an adenoma of the hypophysis, mixed cell-type and with a meningioma fibromatosum localized centroparietally. Both tumours were operated successfully, first the meningioma was removed. The hormone levels did not change after the operation of the meningioma, but normalized after the removal of the hypophysis adenoma. The simultaneously occurrence--without previous irradiation--of such tumours is very rare.
