(Patient No. 3): CT coronary angiography (CTCA) grey-scaled volume rendered (VR) (a), and curved planar reformatted (CPR) (b and c) images in a 7 months infant with KD at presentation show fusiform aneurysm involving entire course of left circumflex coronary artery (LCx) (1 in a and b). A giant aneurysm is seen in proximal left anterior descending coronary artery (LAD) (2 in a and c) and saccular aneurysm in proximal right coronary artery (RCA) (3 in a). RCA beyond aneurysm is not opacified and was interpreted as thrombosed. Giant saccular aneurysm involving proximal LAD (2 in a and c) shows filling defect consistent with thrombus (4 in 2c). Transthoracic echocardiography demonstrated aneurysmal dilatation of proximal segments of RCA and LAD with thrombus, but failed to demonstrate LCx aneurysm.
