Overview

CT scan will show a edematous gland enlarged diffusely, preferably involving the peripheral zone. An abscess can be seen as a hypodensity present in the peripheral zone of the prostate which is unilocular or multilocular and rim-enhancing. On ultrasound, prostatitis can present as a focal hypoechoic region in the peripheral zone of the gland. Collection of fluid with clear boudoirs may suggest the formation of an abscess. Colour Doppler ultrasound can also be very helpful. The diffusely enlarged prostate can be seen on MRI.[1][2]

Imaging findings

CT

Contrast enhanced CT is the preferred imaging study in case an abscess is suspected. CT scan will show a edematous gland enlarged diffusely, preferably involving the peripheral zone. An abscess can be seen as a hypodensity present in the peripheral zone of the prostate which is unilocular or multilocular and rim-enhancing. Central zone can be involved in some cases e.g after the transurethral resection of the prostate (TURP).[1][2][3]

Ultrasound

On ultrasound, prostatitis can present as a focal hypoechoic region in the peripheral zone of the gland. Collection of fluid with clear boudoirs may suggest the formation of an abscess. Colour Doppler ultrasound can be done and may show increase flow in abscess particularly in the periphery.[1]

MRI

The diffusely enlarged prostate can be seen on MRI. It is usually accompanied by inflammatory modifications of the fat around the prostate and the seminal vesicles.[1][4]

Findings of acute prostatitis on MRI include:

  • T1: peripheral zone iso- or hypo-intense to transitional zone
  • T2: hyperintense
  • Gd (C+): diffusely enhancing

Prostate Imaging Reporting and Data System

Prostate Imaging reporting and Data System or PIRADS score is very helpful in diagnosing prostatitis and differentiating it from prostatic cancer.

  • A higher PIRADS score can differentiate prostatic inflammation from carcinoma more reliably.[5]
