A case in favor of aneurysmographic studies: a perforating artery originating from the dome of a basilar tip aneurysm.

Abstract

A posterior perforating artery originating from the dome of a basilar tip aneurysm is reported. The exact origin of this perforator was identified by selective aneurysmography only. This observation provides an argument favoring the consideration of aneurysmographic studies before treatment of large aneurysms located in proximity to areas of normal perforating arteries.
