18F-prostate-specific membrane antigen (PSMA) PET/CT imaging is increasingly used in staging, assessment of biochemical recurrence, and treatment response in men with prostate cancer. We present a case report of a 70-year-old man who underwent 18F-PSMA PET/CT imaging to investigate biochemical recurrence following radical prostatectomy for prostate adenocarcinoma. New focal moderate PSMA uptake was identified in the left femur. A previous PSMA study, performed 5 months earlier, was normal. A subsequent MRI scan demonstrated that the PSMA avidity corresponded to a new femoral bone infarct. An English literature search revealed no previous cases of PSMA tracer uptake in bone infarction.
