Multiple giant aneurysms and stenoses of the coronary and systemic arteries in an infant with kawasaki disease at the early stage of convalescent period.

Myocardial infarction and systemic arterial aneurysms are rarely seen during the course of the Kawasaki disease (KD). Herein, we report the case of a 4-month-old Turkish infant who was diagnosed with KD on the 17th day of the illness. On admission, echocardiogram showed multiple coronary arterial aneurysms (CAAs) and massive pericardial effusion. He was given intravenous immunoglobulin, aspirin and anticoagulant drugs. However, the aneurysms progressed to "super giant" CAAs, multiple huge coronary arterial thromboses developed recurrently and caused myocardial ischemia. Furthermore, the conventional angiography revealed multiple giant aneurysms and stenoses in the subclavian, celiac, and iliac arteries, besides CAAs.
