Abstract

Coronary artery aneurysms are uncommon, are usually associated with atherosclerosis, and rarely involve all three major coronary arteries. The present report describes a rare case of a young female patient presenting with acute myocardial infarction (AMI). Coronary angiography revealed multiple severe aneurysmal and stenotic changes. Based on clinical feature and angiographic findings, it was strongly suspected that the patient had polyarteritis nodosa (PAN) complicated by AMI. The patient was treated with standard cardiac medications and immunosuppressive agents and has remained stable without further complications during a follow-up period of 6 months.

  Fig. 1 Coronary angiography. A: anteroposterior caudal view shows multiple aneurysmal changes of the left main and the left anterior descending artery with total occlusion of the left circumflex artery. B: left anterior oblique cranial view shows a huge aneurysmal dilatation of the proximal part and critical stenotic lesions of the posterolateral branch in the right coronary artery.
