An example of nonspecific bone uptake. ¹⁸F-PSMA PET/CT scan performed on a 71-year-old male with a history of 3 + 3 Gleason score PCa treated with radical prostatectomy (initial PSA levels of 6.3 ng/mL) for initial staging. PET/CT scan revealed a focal PSMA uptake at lateral aspect of right 6th rib (SUVmax of 5.08) without associated osteolytic/blastic lesion. Pathological report from CT guided-biopsy at this lesion revealed benign bone lesion. Follow-up serum PSA in this patient was still low (nadir 0.006 ng/mL).
