title: A giant coronary artery aneurysm in the right coronary artery.
abstract: Aneurysms of the coronary arteries are uncommon occurrences that usually develop secondary to atherosclerosis and are often asymptomatic. They are usually diagnosed incidentally during investigation for ischemic heart disease or at autopsy for sudden death. We present a case of a "giant" right coronary artery aneurysm (CAA) discovered incidentally at surgery. Pathological examination confirmed that this was a true aneurysm showing marked thinning of the media and fibrocalcific plaques with small, multifocal areas of lymphocytic infiltrates.
