title: Absence of the supraclinoid internal carotid artery in association with intracranial aneurysms.
abstract: We report a case of absence of the supraclinoid segment of the left internal carotid artery associated with hypoplasia of the ipsilateral internal carotid artery and anterior communicating artery aneurysm formation. We discuss the embryology probably responsible for this anatomical variant and show the imaging findings.
