The case of a 50-year-old man with a supratentorial dural arteriovenous malformation (AVM) associated with intracerebral hemorrhage is reported. Angiographically confirmed spontaneous regression of the AVM occurred without any form of surgical intervention. A possible mechanism of spontaneous closure of the AVM is offered.
Two malignant intracranial tumors that originated in the paranasal sinuses are described. The patients in both cases were investigated for neurological disorders and had no relevant history of sinus disease. Cerebral angiography demonstrated tumor vascularity identical to meningioma.
