title: Ectopic prolactinoma in the clivus: a case report.
abstract: We report the case of an ectopic pituitary adenoma in a 65-year-old man with an empty sella who initially presented with right ptosis and eyelid edema and headache. Neuroimaging studies revealed a large tumoral process at the height of the clivus, with partial destruction of surrounding bone structure. He underwent transphenoidal surgery and histopathologic examination, including immunohistochemical studies, revealed a prolactin-producing pituitary adenoma. A careful review of the literature was done.
