Soft tissue metastasis of the penis detected by copper-۶۴ labeled prostate-specific membrane antigen positron emission tomography (۶۴Cu –PSMA PET/CT) in a patient with prostate cancer

Prostate cancer is considered to be the most common solid cancer affecting men worldwide and leading to a significant morbidity and mortality.  Metastases are usually seen in bone or lymph nodes. For recurrent disease, PET imaging with ۶۸Ga-PSMA-۱۱ (also known as HBED-CC, Glu-urea-Lys(Ahx)-HBED-CC, and PSMA-HBED-CC) is widely used. However, preparation of ۶۸Ga-PSMA ligand requires the presence of radiochemistry facilities and can therefore not be utilized in centers lacking such facilities. Recently, copper labeled prostate-specific membrane antigen positron emission tomography (۶۴Cu-PSMA PET/CT) demonstrated promising results in patients with recurrent disease and in the primary staging of selected patients with progressive local disease. In the present case, a rare manifestation site of a metastatic lesion in a patient with advanced prostate cancer is detected by ۶۴Cu-PSMA PET/CT.
