Giant right coronary artery aneurysm secondary to Kawasaki disease in an infant

Abstract

Kawasaki disease (KD) is a potentially decapacitating multisystemic vasculitis with unknown etiology that acquired worldwide attention due to associated coronary aneurysms leading to life-threatening complications in very young babies including thrombosis, ischemia, and rupture. High levels of suspicion for early diagnosis and prompt treatment are crucial in preventing serious complications. We report here one of the patients who developed a giant coronary aneurysm but fortunately not a life-threatening complication after 5 years of follow-up. We conclude that later intravenous immunoglobulins (IVIG) treatment could be an important factor—among others—that precipitate into such complications.
