摘要：

A 58-year-old man with metastatic prostate cancer was treated with prostatectomy, radiation therapy to bone metastasis, and androgen deprivation therapy plus abiraterone. He had posttreatment nadir PSA of 0.1 ng/mL. A follow-up F-18-fluciclovine PET performed with PSA of 0.3 ng/mL showed a focal tracer-avid lesion in the left prostatectomy bed. This lesion was negative on F-18-DCFPyL PET/CT, but with typical MRI features for disease recurrence. Minimal urinary activity of fluciclovine helped detection of local disease recurrence in the prostatectomy bed.
