FATAL EPISTAXIS FROM AN ANEURYSM OF THE INTRACRANIAL INTERNAL CAROTID ARTERY

Abstract

An instance of fatal epistaxis is reported in a patient with an unsuspected aneurysm of the infraclinoid portion of the internal carotid artery. There was no known history of trauma. The aneurysm was subsequently detected on an old X-ray film. Epistaxis from an aneurysm at this site is nearly always preceded by significant head trauma and is associated with cranial nerve palsies, a syndrome with a high mortality. Epistaxis from rupture of a non-traumatic aneurysm is very rare.
