Figure 1. (a) Axial section contrast-enhanced CT demonstrating a giant (9 mm) aneurysm of the distal left main stem artery and a further moderate-sized (6 mm) aneurysm of the left anterior descending and circumflex artery origins. (b) A "curved multiplanar reformation (MPR)" helps to more accurately demonstrate the calcified, saccular nature of the giant aneurysm and morphology of the more distal aneurysm.
