Anterior spinal artery aneurysm presenting as a subarachnoid hemorrhage.

Abstract

A woman who presented with a subarachnoid hemorrhage secondary to a ruptured anterior spinal artery aneurysm of the spinal cord is reported. While this is the first report of a ruptured aneurysm of the anterior spinal artery with angiographic confirmation, it emphasizes that occasionally subarachnoid hemorrhage may be secondary to ruptured spinal artery aneurysms.
