A conventional coronary angiographic image at a right anterior oblique-caudal view. Two aneurysms are homogenously enhanced by contrast (A and B). The largest aneurysm shows irregular enhancement in the periphery (black arrows), and most of the central area are filled with thrombus (C). The second aneurysm of the left circumflex artery shows homogenous filling with contrast material (B). Faint contrast staining is noted on the distal side of the largest aneurysm (white arrows). A delayed image might have shown collaterals that were seen on CT angiography. Ra, ramus intermedius; CT, computed tomography.
