Figure 1. Computed tomography angiography (maximum intensity projection) of the left upper extremity taken at time of presentation, showing multiple areas of occlusion and findings consistent with vasculitis. Complete occlusion of a 4.5-cm segment of the left subclavian artery at the level of the clavicle (arrowheads) is present with re-opacification distally from collaterals. Another 2.5-cm segmental occlusion is evident involving the distal brachial, proximal radial, and proximal ulnar arteries at the level of the bifurcation (single arrow) with re-opacification of the radial and ulnar arteries by collaterals surrounding the elbow. Finally, there is an 8.1-cm segmental occlusion of the ulnar artery extending from the mid-forearm to the level of the wrist (double arrow) with reopacification of the ulnar artery more distally near the level of the wrist.
