Incomplete kawaski disease: Are we missing it?

Kawasaki disease, also known as mucocutaneous lymph node syndrome or infantile polyarteritis nodosa is an acute febrile vasculitis of unknown etiology with a predilection for coronary arteries and potential for aneurysm formation. In Incomplete Kawasaki disease, children with fever lack the sufficient number of criteria to fulfill the epidemiologic case definition and are diagnosed when coronary artery disease is detected. We present a case report of a one and a half years old girl who came with features of incomplete Kawasaki disease, high grade fever, irritability, history of conjunctivitis and cracking of lips. She was investigated and had a platelet count of 902 × 10⁹/L, ESR was 71mm/hr and CRP was also raised to 12.8mg/l. Cardiac evaluation and echocardiography was done which showed dilated coronary arteries >3mm on the left side and 4mm on the right side with early aneurysmal changes . She was treated with immunoglobulin and aspirin and improved.
