Figure 2 (A) Multislice computed tomography: diffuse wall thickening of the left main coronary artery and left anterior descending (LAD) artery, with some calcifications limited to small, calcified, parietal nodules (white arrows) and non-calcified plaques (black arrows). Note some irregularity of the proximal LAD and diffuse narrowing of the distal LAD. There was no significant coronary stenosis. (B) Same patient, with conventional coronary angiography: normal aspect of the circumflex artery (Cx); diffuse wall thickening of the LAD was seen as diffuse narrowing of the coronary lumen. Ao = aorta.
