A Rare Case of Superficial Temporal Artery Pseudoaneurysm in the Context of Endocarditis

Infectious aneurysm related to endocarditis is a complication that usually involves the distal middle cerebral artery branches.There is paucity in the literature of cases involving the common or external carotid arteries, which are extremely rare.We report the case of a previously healthy 30 years old female with bacterial endocarditis-related infected skin lesions, complicated with infectious aneurysm involving a distal segment of the frontal branch of the right superficial temporal artery, intraparenchymal hematoma and septic embolisms.To our knowledge, this is the first case reported of an infectious aneurysm involving a distal external carotid artery branch in the context of proven bacterial endocarditis.
