Figure 2. A 39-year-old patient with a previous hysterectomy for uterine non-Hodgkin's lymphoma, referred for suspected central nervous system recurrence (patient no. 6). (a) On PET data (from left to right: coronal, sagittal and transaxial images) increased FDG uptake was detected in the right abdomen (arrows). (b) On PET-CT (from left to right: CT, PET and fused PET/CT images) the increased uptake corresponded in location to a soft-tissue mass posterolateral to the cecum, adjacent to surgical clips, identified as a transposed ovary (arrows). (c) PET/CT study performed 6 months later, without treatment in the interim. The transposed ovary shows no increased uptake, confirming the functional aetiology of FDG uptake on the first study (arrow).
