soft tissue metastasis of the penis detected by copper-64 labeled prostate-specific membrane antigen positron emission tomography (64cu –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 68ga-psma-11 (also known as hbed-cc, glu-urea-lys(ahx)-hbed-cc, and psma-hbed-cc) is widely used. however, preparation of 68ga-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 (64cu-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 64cu-psma pet/ct.
