Although very rare, aneurysms of the extracranial carotid artery (ECAA) are important to identify and treat. The most common definition is a dilation of the carotid artery greater than 150% of the diameter of normal (uninvolved) internal carotid artery (ICA) or common carotid artery (CCA). ECAAs are most frequently located in the ICA and the dilation may be focal and saccular or fusiform and extensive. The natural history of ECAA remains unclear (largely because of their rarity and because most are probably treated), but there is an intuitive belief that they rarely remain benign. Untreated, ECAA can cause compression in the cervical region, causing swelling, pain, and cranial nerve palsy. Embolization of thrombus from within the aneurysm can cause cerebral infarction, while the risk of aneurysm rupture is probably very low.
