Abstract
A five-month-old infant presented with eight days of fever, marked irritability and minimal mucocutaneous signs, meeting fewer than three classical criteria for Kawasaki disease. Inflammatory markers were high and platelet count rose progressively from the second week. Echocardiography on day 11 demonstrated a 5.2 mm right coronary artery aneurysm. Intravenous immunoglobulin and aspirin were commenced immediately, with defervescence within 36 hours and gradual aneurysm regression over eight months. Incomplete Kawasaki disease is disproportionately common under six months of age and carries the highest coronary risk; early echocardiography should not be deferred while waiting for diagnostic criteria to be satisfied.
