A 33-year-old male with a history of non-seminoma germ cell tumor, previously treated with left orchidectomy, chemotherapy, and retroperitoneal lymph node dissection for bulky para-aortic lymph node metastases, presents for a progress assessment. The PET scan (Image A) demonstrates mild foci of uptake around the aortocaval (SUV max 3.9) and left para-aortic (SUV max 3.3) regions at the level of L3, adjacent to surgical clips (red arrows, a-c), which were reported as indeterminate (either post-surgical inflammatory changes or residual disease). Twelve months later, a follow-up PET scan (Image B) showed an interval reduction in the intensity of retroperitoneal foci of uptake (d-f), consistent with resolving post-operative inflammatory changes
