UNLABELLED: We report two patients with incomplete Kawasaki disease that presented as apparent urinary tract infection. Persistent fever and pyuria were the initial presentation without concomitant signs suggestive of Kawasaki disease; thus the patients were treated as urinary tract infection. Fever persisted despite antibiotic treatment. Diagnostic criteria of Kawasaki disease were not fulfilled for these two patients, yet aneurysmal dilatation of the coronary artery was noted 10 and 18 d, respectively, after the onset of fever. The diagnosis of incomplete Kawasaki disease was assigned when the coronary artery abnormality was detected. Fever subsided within 24 h of administration of intravenous immunoglobulin. CONCLUSION: This report highlights the potentially misleading presentation of fever and pyuria as the sole initial manifestation of incomplete Kawasaki disease. Echocardiography is indicated to detect coronary artery abnormality when fever persists in such patients after adequate antibiotic treatment and thorough urological evaluation.
