title: Multiple segmental agenesis of the cerebral arteries: case report.
abstract: A case of multiple segmental agenesis of the cerebral arteries is presented. Cerebral angiography demonstrated bilateral so-called carotid rete mirabile, a similar "rete" of the right vertebral artery and intradural duplication of the left vertebral artery. These abnormalities are thought to be caused by multiple segmental agenesis of the cerebral arteries as they penetrate the dura mater. The embryological and anatomical significance of these findings is discussed.
