Mycotic Cerebral Aneurysm: A Rare Complication of Infective Endocarditis

Abstract

Intracranial mycotic aneurysm or Infected Aneurysm (IA) is rare and accounts for 2-4 % of neurologic complications of infective endocarditis [1]. The terminology «mycotic aneurysm» was used for the first time by William Osler in Gulstonian Lectures of 1885, it refers to a dilatation of an arterial wall caused by any infectious etiology [2]. It is a serious clinical condition that carries a significant morbidity with up to 80% mortality rates when reptured [3]. Therefore, an early and rapid diagnosis is critical for timely treatment to optimize patient outcome.
