Mycotic aneurysms of coronary arteries.

Bacterial endocarditis may give rise to mycotic arterial aneurysms in any part of the body, but particularly in the thoracic aorta, intracranial vessels, superior mesenteric artery, and the large arteries to the extremities (Weintraub and Abrams, I968). Aneurysms occurring in the coronary arteries are commonly arteriosclerotic or congenital and are very rarely mycotic in origin (Daoud et al., I963). This report concerns a patient in whom the diagnosis of mycotic coronary arterial aneurysms was made in life by means of coronary arteriography.
