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.[1][2][3][4]

CT scan

When an abscess is included in the differential diagnosis of prostatitis, a contrast CT scan is preferred. CT scan in a patient with prostatitis shows edema of the prostate gland with diffuse enlargement, mostly in the peripheral zone. An abscess can also be identified as a rim enhancing hypodensity which can either be unilocular or multilocular. Central zone can be involved rarely such as after the transurethral resection of the prostate (TURP).[1][2][5]
