Atypical Kawasaki disease: A patient with coronary,brain, and internal mammary arteritis

Here we report a rare case of atypical Kawasaki disease (KD) in a patient presenting with systemic arteritis affecting the coronary arteries, brain, and internal mammary arteries (IMAs). A 25‐year‐old man was referred to our institute with angina pectoris. Coronary angiography revealed coronary artery aneurysms and triple‐vessel disease. Three‐dimensional brain computed tomography showed multiple small saccular aneurysms on the vertebral and posterior inferior cerebellar arteries. Off‐pump coronary artery bypass (OPCAB) grafting ??????was performed; however, the bilateral IMAs were tightly adhered and not patent. OPCAB was completed using the bilateral radial and gastroepiploic arteries. This is the first report of KD involving the IMA.
