Abstract
A case of pituitary adenoma associated with a falcotentorial junction meningioma is presented. A 50-year-old female having a 12-year history of acromegalic features and a 3-year history of visual disturbance was admitted because of headache, vomiting, and a floating sensation. On admission acromegalic appearance, bitemporal hemianopsia, and truncal ataxia were noted. Computed tomography scan showed two mass lesions on the midline, one in the suprasellar region and the other in the retropineal region. With angiographical and endocrinological examinations, coexistence of a pituitary adenoma and a falcotentorial junction meningioma was diagnosed. Two operations were performed and the preoperative diagnosis was confirmed histologically.
Regarding the simultaneous occurrence of pituitary adenomas and meningiomas, only 7 cases were reported previously. A falcotentorial junction meningioma itself is also rare. Only 21 such cases were found in the literature. The clinical manifestation and the management of falcotentorial junction meningiomas are discussed.
