Atypical Kawasaki disease: coronary aneurysms and thrombocytopenia

Abstract

The patient we have described had coronary artery aneurysms pathognomonic for Kawasaki disease after a nonspecific febrile illness not meeting the classic clinical criteria. The child had significant thrombocytopenia, which in the past has been thought to militate against the diagnosis of Kawasaki disease. Echocardiography should be considered in febrile infants with thrombocytopenia of uncertain etiology.
