Coronary Artery Aneurysm in a 4-Month-Old Infant with Incomplete Kawasaki Disease

Abstract

Kawasaki Disease (KD) is a type of inflammatory vascular disease that targets the medium vessels with a predilection for coronary arteries. The atypical presentation, called incomplete Kawasaki Disease, is common among children below six months. It presents as a fever with less than four of the KD clinical criteria. This report looks into a case of a four-month-old infant with features of incomplete KD who presented with a fever 38.7o C for four days, polymorphic skin rashes for 2 days, and diarrhea for 1 day. Initially, the child was being treated for urinary tract infection due to the presence of leukocytes on urinalysis. The case of incomplete KD was diagnosed upon echocardiographic confirmation of large and giant aneurysms on the right and left coronary arteries, respectively. The child improved with the administration of management for KD, including intravenous immunoglobulins and aspirin. This case shows the indiscernible presentation of incomplete KD, warranting a need to critically evaluate incomplete KD as one of the differential diagnoses when a child presents with an unexplained fever.
