Ga-68 labeled prostate-specific membrane antigen (PSMA) whole body PET/CT scan is a novel upcoming modality for the evaluation of prostate cancer. We present three cases of prostate cancer showing rare sites of metastases like brain, penis, and liver detected on Ga-68 PSMA PET/CT scan thus emphasizing its role in lesion detection and staging.
Keywords: Ga-68; PSMA; metastases; prostate cancer.
