Abstract:
A 78-year-old man was referred for investigation of prostate cancer following incidental uptake on 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET). Despite normal PSA and benign digital rectal exam, he was referred for consideration of trans-perineal biopsy to exclude prostate cancer. It was only on review of imaging that it became clearly apparent that the 18F-FDG uptake was due to urinary tracer pooling in a trans-urethral resection cavity. Surgeons, oncologists and nuclear medicine physicians should be aware of this common pitfall in interpretation of 18F-FDG-PET in the prostate.
