Giant coronary sinus aneurysm and multiple coronary artery aneurysms in a pediatric patient

Abstract

Giant coronary sinus aneurysm is extremely rare in pediatric population. It was first reported in 1983 by Ho SY et al. Cerebrovascular accident, shock, myocarditis and severe myocardial dysfunction requiring extracorporeal membrane oxygenation are also very rare presentations of Kawasaki disease. Such rare cases are often misdiagnosed at first as septic shock. Kawasaki disease should be considered in all children presenting with toxic shock. This article reports a rare case of giant coronary sinus aneurysm that also had unusual presentation of Kawasaki disease with cerebrovascular accident, shock, myocarditis and severe myocardial dysfunction requiring extracorporeal membrane oxygenation. In our patient, Kawasaki disease was initially misdiagnosed. It was retrospectively diagnosed when cardiac magnetic resonance imaging was performed to evaluate coronary sinus aneurysm.
