Axial C+ arterial phase
Right-sided aberrant subclavian artery demonstrating arteriosclerotic stenosis at its origin.
Aneurysmal dilatation of ascending aorta.

In this case, the aberrant artery is significantly stenosed by atherosclerotic plaque causing the aforementioned difference in blood pressure.
