Axial non-contrast CT and PET-CT images for a 60-year-old male patient with history of prostate cancer for which he had chemotherapy and radiotherapy. Images a and b showed prostatic lesion with 68Ga-PSMA activity with SUVmax = 17.5 with posterior extra-prostatic extension and obliteration of the recto-prostatic space (red arrows), denoting residual neoplastic lesion. Images c and d showed 68Ga-PSMA activity by metastatic left external iliac lymph node with SUVmax = 10.6 (blue arrows). Images ad showed 68Ga-PSMA activity by metastatic sclerotic osseous lesions involving the pelvic bones (green arrows)
