Coronary artery aneurysm is defined as coronary dilatation with a diameter of more than 1.5 times the adjacent normal coronary artery. Most of the coronary aneurysms remain asymptomatic. More than 90% of coronary aneurysms are of atherosclerotic origin. Nonatherosclerotic coronary aneurysms are rare, and the majority of them are diffuse. Among the three major coronary arteries, the left circumflex artery is the least commonly involved. The management strategies for nonatherosclerotic coronary aneurysms are not clear, and each case should be managed on an individual basis depending on the clinical context. Here described is a case of a discrete nonatheroscle rotic aneurysm of the left circumflex coronary artery in a 46-year-old man who presented with accelerated angina pectoris and was treated medically. The patient was free of symptoms on 2-year follow-up. The clinical perspectives of the nonatherosclerotic coronary aneurysm are discussed.
