title: Epididymal Metastasis of Prostate Cancer Detected With 68Ga-PSMA-PET/CT.
abstract: Here, we report on a 73-year-old man with a biochemical relapse (PSA level, 1.1 ng/mL) 8 years after radical prostatectomy and radiotherapy. Four years after primary diagnosis, a bilateral subcapsular orchiectomy was performed for endogen androgen deprivation. Physical examination and transrectal ultrasound did not show any suspicious finding. Subsequently, a Ga-PSMA-PET/CT was performed and revealed a very rare epididymal metastasis. After surgery, the PSA level decreased to less than 0.07 ng/mL, and 4 months later, the patient is still tumor free.
