Figure 1

Contrast-enhanced computed tomography of aneurysm of the left subscapular artery. Oblique maximum intensity (A) and volume rendering (B) projections of contrast-enhanced computed tomography show a 1cm-diameter aneurysm of the left subscapular artery (arrowheads), associated with a blush of contrast agent (asterisks). More proximally, there is an extensively calcified chronic total occlusion of the proximal left subclavian artery (arrows). Of note, there is an aberrant origin of the right subclavian artery.
