Penile Metastasis from Prostate Cancer Presenting as Malignant Priapism Detected Using Gallium-68 Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography.

Gallium-68 prostate-specific membrane antigen positron emission tomography/computed tomography (Ga-68 PSMA PET/CT) is a promising diagnostic tool for patients with prostate cancer. Penile metastasis from prostate cancer is a rare phenomenon that infrequently manifests as malignant priapism. We present a case of 79-year-old patient diagnosed as a case of adenocarcinoma prostate presenting with penile metastases imaged using Ga-68 PSMA PET/CT.
