Fatal subarachnoid hemorrhage from the rupture of a totally intracavernous carotid artery aneurysm: case report

Abstract

Intracavernous carotid artery aneurysms usually cause symptoms because of gradual expansion without rupture. Most such aneurysms that do rupture lead to a carotid-cavernous fistula. Very few cases of rupture leading to subarachnoid hemorrhage have been reported. We report a case in which rupture of an entirely intracavernous carotid artery aneurysm led to death from a massive subarachnoid hemorrhage.
