Abstract:
A 68-year-old man with treated prostate cancer 3 years earlier and small cleaved B-cell follicular lymphoma diagnosed 1 year prior and monitored clinically with no active intervention ("watch and wait" approach) was referred for Ga-prostate-specific membrane antigen (PSMA) PET/CT with rising prostate-specific antigen level. PET/CT demonstrated diffuse PSMA uptake in the prostate (SUVmax 3.6) and multiple PSMA-avid nonenlarged lymph nodes. Moderate PSMA uptake (SUVmax 4.7) was also noted in an enlarged right inguinal lymph node (SUVmax 4.7), which on core biopsy confirmed small cleaved B-cell follicular lymphoma.
