ECD detectable on FDG PET, but not on CT, in a 41-year-old male. (a) Axial FDG PET, (b) axial non-contrast CT, and (c) axial-fused FDG PET/CT through the level of the testes demonstrate FDG-avid bilateral testis ECD with an SUVmax of 12.0 (arrows). While the disease is detectable on FDG PET and measurable by mPERCIST, the testes are of normal size and without focal lesion on CT
