title: Ectopic pituitary adenoma associated with an empty sella: a case report and review of the literature.
abstract: A case of ectopic pituitary adenoma in the sphenoid sinus associated with an empty sella is reported. The coexistence of an ectopic pituitary adenoma and an empty sella is quite rare. The diagnosis was made with an intraoperative finding of the intact dura mater of the sellar floor. In the present case, the hypointense line that coated the pituitary gland was clearly demonstrated on 3-tesla T2-weighted magnetic resonance imaging. The hypointense line is considered to be the pituitary capsule and was critical in diagnosing this rare entity.
