Abstract
Kawasaki disease (KD) involves coronary aneurysms and can infrequently cause systemic artery aneurysms (SAAs). Therefore, patients with KD should be evaluated for both coronary and systemic arterial aneurysms. This report describes 2 cases of SAA evaluated using the diastolic phase image of electrocardiogram-gated three-dimensional fast spin echo during noncontrast magnetic resonance angiography. The first case was a 1-year-old male who diagnosed with KD at 2 months of age. Multiple right axillary artery aneurysms measuring 6.0 mm and 2.5 mm and left axillary artery aneurysms measuring 12.0 mm, 4.0 mm, and 3.0 mm were observed by scanning for 94 seconds. The second case was a 13-year-old male who diagnosed with KD at 4 months of age, with a 7.0-mm right axillary artery aneurysm observed by scanning for 101 seconds. Electrocardiogram-gated three-dimensional fast spin echo in the diastolic phase can help evaluate SAA in patients with KD and does not require a prolonged scanning time or contrast medium.
