Cavernous hemangioma in the pineal region.

A cavernous hemangioma in the pineal region of a 22-year-old man is reported. Because the patient had diabetes insipidus and a contrast-medium-enhanced mass in his pineal region on computed tomography, a germinoma was suspected. A ventricular shunt was made and the tumor was irradiated, but without a response. After irradiation the tumor was entirely removed, and postoperatively the diabetes insipidus improved.
