Incomplete Kawasaki disease may present significant diagnostic challenges in young infants, frequently leading to delayed diagnosis and severe coronary complications. We report on a 3.5-month-old infant with a delayed diagnosis of incomplete Kawasaki disease who developed bilateral giant coronary artery aneurysms with progressive coronary obstruction. Despite appropriate medical management including immunoglobulin therapy and antithrombotic treatment, the patient developed ischemic heart failure and ultimately required coronary artery bypass grafting. This case highlights the diagnostic difficulty of incomplete Kawasaki disease in early infancy and emphasizes the importance of early echocardiographic evaluation in infants with prolonged unexplained fever.
