A 32-year-old male with non-seminomatous testicular cancer, initially treated with orchidectomy, presented with suspicious para-aortic lymph nodes on CT and underwent an FDG PET scan. The images reveal a subcentimetre left supraclavicular lymph node (SUVmax 3.5; images a-c, crosshairs), bilateral intensely FDG-avid retrocrural lymph nodes (SUVmax 8 on the right and 12 on the left; images d-f, red arrow), and bilateral para-aortic lymphadenopathy extending from the axial level of L1 to L2/L3 on the right (SUVmax 21) and from the axial level of L1/L2 to L2/L3 on the left (SUVmax 25; images g-I). A subsequent biopsy of the left supraclavicular node confirmed metastatic involvement. Retroperitoneal lymph node dissection also confirmed multifocal retroperitoneal nodal metastases
