Convexity meningioma with galactorrhea and hyperprolactinemia. A case report.

A case is reported of a huge convexity meningioma associated with galactorrhea and an elevated serum prolactin level of 41 ng/mL. Total removal of the tumor resulted in a return of the prolactin level to normal (9.7 ng/mL). Because of a severe mass effect, the distant tumor might have encroached upon the hypothalamic-pituitary axis and interrupted PRL inhibitory factor regulation.
