Figure 2.

FDG PET/CT scan of the same patient in Figure 1 revealed no focally increased FDG uptake or suspicious abnormalities to bone on the CT of the right sacroiliac area to correspond the bone scan findings (short arrows). The patient's history of pelvic fracture probably explained the focal tracer uptake in bone scan. The recurrent colon cancer in the left pelvis observed by both PET and CT scans is marked by the long arrows.
