Widespread Metastatic Prostate Carcinoma Shown by 68Ga-PSMA PET/CT.

We present the F-FDG and Ga prostate-specific membrane antigen PET/CT images of a 61-year-old patient with a newly diagnosed prostate carcinoma (4 + 4 Gleason score) and high serum prostate-specific antigen levels (460 ng/mL). In F-FDG PET/CT, minimal uptake was demonstrated in the prostatic mass without any accompanying pathological uptake. However, Ga prostate-specific membrane antigen PET/CT revealed multiple pathological uptake in the lung nodules, mediastinal nodes, abdominal-pelvic lymph nodes, bone lesions, and prostatic mass.
