CT scan in a patient with prostatitis shows edema of the prostate gland with diffuse enlargement, mostly in the peripheral zone. If the fever fails to resolve after 36 hours of therapy an abscess is suspected and needs further workup to rule out this possibility. An abscess may be seen as a rim enhancing hypodensity which can either have  single or multiple locuses.
