title: Abnormal left cardiac border due to an atherosclerotic coronary artery aneurysm.
abstract: A 57-year-old man had an aneurysm of the left anterior descending coronary artery that appeared as a bulge of the left cardiac border on plain chest roentgenograms. The aneurysm enlarged over a four-year period, and death resulted from myocardial infarction. The importance of recognizing this uncommon cause of an abnormal left cardiac border is stressed because further investigation by coronary angiography should be done before resection or bypass of the aneurysm.
