Abstract
-
The authors report a case of angiographycally occult intracranial vascular malformation. The patient had huge calcified mass at left frontoparietal area. The preoperative diagnosis was a slowly growing benign tumor. The mass was very hard and so vascular malformation was not suspected even during the operation. Pathologic report revealed arteriovenous malformation.
