We present a case of a 63-year-old gentleman, who had an initial negative prostate needle biopsy, but persistently elevated prostate-specific antigen levels. An magnetic resonance imaging study of the prostate failed to demonstrate the presence of malignancy. 18F-fluorocholine positron emission tomography/computed tomography (PET/CT) was then acquired which revealed suspicious prostate lesions. These were confirmed by subsequent surgery and histology to represent prostatic carcinoma.
