Figure 4. Upper panel: whole-body FDG-PET demonstrating moderately enhanced homogeneous uptake in both the lesions; the SUVmax of the right gluteal mass was 3.6 and that of the abdominal desmoid was also 3.6. Lower panel: a delayed limited PET (obtained at 2.5 h after injection of FDG) of the right gluteal region registered an increase in the SUVmax to 4.4 (increase of 24.71%).
