title: Polyarteritis nodosa complicated by chronic total occlusion accompanying aneurysms on all coronary arteries.
abstract: Polyarteritis nodosa (PAN) is characterized by inflammatory necrosis of medium sized arteries. PAN can also be associated with stenosis or aneurysm of the coronary artery. However, the involvement of PAN at a coronary artery is usually asymptomatic, which makes it difficult to diagnose. In addition, all of the three main coronary arteries involved with chronic total occlusion (CTO) is a rare finding in patients with PAN. We report a patient that presented with PAN complicated by CTO and aneurysms of three main coronary arteries, without typical symptoms of angina.
