title: Successful evacuation of a pontine hematoma secondary to rupture of a venous angioma.
abstract: A middle-aged woman presented with progressive brainstem neurological deficits. Clinical manifestations and preoperative radiological examination were indicative of an expanding intrapontine mass. At operation, an intrapontine hematoma and a venous angioma adherent to the floor of the fourth ventricle were discovered. Successful evacuation of the hematoma was followed by an excellent recovery. Postoperative angiography demonstrated the venous angioma. To our knowledge, this is the first case of angiographically proved ruptured venous angioma of the pons treated successfully by an operation.
