Figure 3. A PET/CT scan (April 2016) after adequate alpha and beta blockade revealed the stable size of the large heterogeneous right adrenal mass (outlined in Figures 3A-3B) with moderate FDG uptake with areas of central photopenia, which likely correspond to central necrosis. There is intense FDG uptake in the perinephric space with a maximum SUV of 7.4 compared to 10.2 in the previous study.

PET/CT - Positive emission tomography/computed tomography, FDG - fluorodeoxyglucose, SUV - standardized uptake value.
