Kawasaki disease. Coloured angiogram (X-ray) of abnormal coronary arteries in a child suffering from Kawasaki disease. The large aorta artery (yellow) forms a loop, which appears to end at centre where this artery exits from the heart (not visible). At this point, small coronary arteries are visible coming off the aorta. These coronary arteries are abnormal and weakened in that they bulge into balloon shapes (aneurysms) along their lengths. Kawasaki disease is a childhood illness between ages 1-2 years. Fever, swollen lymph nodes and a rash occurs. Coronary artery disease (seen here) may also occur with heart complications, and some cases result in heart failure and death.
