Dural arteriovenous fistula supplied by the artery of Davidoff and Schechter

摘要

Dural arteriovenous fistulae are common intracranial vascular anomalies. They are usually supplied by meningeal branches of the internal or external carotid arteries. When they occur in the posterior fossa, they are usually supplied by the posterior meningeal branches of the vertebral artery, in addition to the external carotid artery. In this case report we highlight a rare meningeal contribution to the dural arteriovenous fistula (DAVF) from the posterior cerebral artery.
