Incidentally detected thrombosed vein during ⁶⁷Ga citrate scanning

A patient with stage IVA Hodgkin's disease developed thrombosis of the right cephalic vein at the site of an indwelling catheter. A few weeks later, 72 and 96 hr scans after injection of ⁶⁷Ga citrate revealed an increased linear uptake where the thrombosed vein was palpated. As far as we know, this is the first case showing abnormal uptake of this agent in a thrombosed vein. It is postulated that residual chronic inflammatory cells are responsible for ⁶⁷Ga citrate uptake in this case.
