title: Unusual presentation of traumatic extracranial internal carotid artery aneurysm.
abstract: A young man presented with apparent transient ischemic attacks following a motorcycle accident in which he sustained minor injuries only. Computerized axial tomography demonstrated a small right frontal infarct, and angiography revealed an aneurysm of the right internal carotid artery in its extracranial course. This was thought to be traumatic in origin.
