Ectopic pituitary adenoma of the sphenoid sinus: report of a case and review of the literature

Abstract

Ectopic pituitary adenoma of the sphenoid sinus in a 68-year-old woman is presented. The confusing discrepancy between the imaging features and the mild clinical manifestations of extensive bone destruction of the skull base is emphasized. A definite diagnosis can be established only by histopathological examination supported by immunohistochemical studies.
