A Case of Polyarteritis Nodosa Associated with Vertebral Artery Vasculitis Treated Successfully with Tocilizumab and Cyclophosphamide

Bone scan at diagnosis. Bone scan: multifocal areas of uptake in the bilateral forearms most pronounced in the right ulna and radius (thin, long yellow arrow) as well as the left ulna and radius (thin short yellow arrow) and right proximal tibia (arrowhead). Gallium scan (not shown) obtained at this time demonstrated subtle increased uptake corresponding to the areas of increased activity on the bone scan, but the activity was less intense than the bone scan, supporting this to be inflammatory process. There was also soft tissue uptake in the right forearm.
