Abstract:
New radiotracers for positron emission tomography imaging that target prostate-specific membrane antigen (PSMA) have emerged as important clinical tools for imaging prostate cancer (PCa). PSMA-targeted radiotracers have demonstrated high sensitivity and high specificity for detecting sites of PCa and are demonstrably superior to conventional imaging modalities such as computed tomography and bone scan. Vas deferens invasion is a rarely encountered poor prognostic feature of PCa. In this case report, we describe a novel pattern of radiotracer uptake in a patient with PCa imaged with PSMA-targeted 18F-DCFPyL positron emission tomography/computed tomography that is consistent with diffuse vas deferens involvement.
