Giant Aneurysm of Left Coronary Artery of 18-Month-Old Infant: A Case Report

Kawasaki disease is a medium-size vasculitis with peak incidence among infants of 9 to 11 month age. This case report represents a female infant of 18-month age whom was admitted to the Taleghani Pediatric Center of Gorgan, Iran; with referral for admission due to persistent fever for roughly 2 weeks despite various outpatient treatments. Upon the admission, Echocardiographic study was performed to assess whether the patient fulfils cardiac criteria of Kawaski disease which was consistent with the diagnosis and also positive for serious coronary complications in the infant. General condition of the patient improved as the treatment with both IVIG and Corticosteroids was initiated and carditis seemed to vanish in echocardiographic studies but as expected aneurysmal growth can last for over 80 days and in this case serial echocardiographic studies confirmed the formation of giant coronary aneurysms. Diagnosis of Kawasaki disease is based on persistent fever and consistency with clinical criteria and the main purpose of this case report was to emphasize the need to consider this disease in cases of persistent fever to avoid the serious following complications.
