Abstract
Coronary cameral fistulas are rare anomalous connections between coronary circulation and cardiac chambers. Coronary cameral fistulas are often asymptomatic but may cause volume overload on impacted chambers, and also create high velocity turbulent diastolic flow which may predispose patients to endocarditis. This paper presents a unique case of infective endocarditis revealed by intracerebral hemorrhage with a mycotic aneurysm in a patient who was found to have a nonvalvular infective endocarditis located on the mitral anterolateral papillary muscle, at the ventricular site of entrance of a large coronary cameral fistula.
