Separate Origin of the Left Internal and External Carotid Artery from the Aortic Arch Associated with Contralateral Intracranial Giant Aneurysm

Abstract

One of the rare anomalies of the common carotid artery is the separate origin of the internal and external carotid artery. We present the case of a patient who was admitted to hospital for cerebral angiography to exclude an intracranial aneurysm. The DSA revealed a giant aneurysm of the right internal carotid artery and separate origins of external and internal carotid arteries from the aortic arch. To our best knowledge no similar case has previously been reported.
