3. CT of the abdomen and pelvis shows a left pelvic mass

The CT of the abdomen and pelvis, performed in unenhanced and enhanced phases, shows resolution of the right adnexal process seen two years earlier, but reveals a strongly enhancing left pelvic mass in approximately the same location as the study performed two years earlier (Figure 3).
Based on the findings at the repeat CT abdomen and pelvis, the patient underwent 18FDG – PET scan (Figure 5).

Which of the following represents an appropriate interpretationfor this examination? (click on the correct answer to be directed to the fifth of twelve pages)

1. 18FDG – PET shows widespread nodal hypermetabolic activity
2. 18FDG – PET shows hypermetabolic activity in the right adnexal region
3. 18FDG – PET is non-diagnostic, probably owing to improper fasting
4. 18FDG – PET shows hypermetabolic activity within the left pelvis mass
5. 18FDG – PET shows mild hypermetabolic activity traceable to the colon, reflecting nonspecific uptake
