Case Three - Staging FDG-PET/CT demonstrates a bulky and intensely FDG-avid pelvic mass, with absent left scrotal testicular activity [circle] (a). A small focus of mild FDG-uptake (SUVmax 4.9) in the upper abdomen corresponds with a 10 mm left para-aortic node on the co-acquired non-contrast enhanced CT [red arrow] (a1–3). Re-staging 18F-FDG-PET/CT following pelvic resection revealed interval metabolic and structural progression of the left para-aortic node [orange arrow] (20 mm; SUVmax 13.4), with a chain of new FDG-avid subcentimetre nodes cranially (B1–3)
