Prostatic abscess evaluated by serial computed tomography

Abstract

Prostatic abscess appears on computed tomography (CT) as multiple, well-demarcated fluid collections within the prostate gland and/or periprostatic tissues. Since prostatic abscess may not be differentiated from other prostatic disease on the basis of history and physical examination alone, CT can contribute significantly to establishing this diagnosis. Prostatic abscess can be an aggressive lesion within the pelvis and may rupture into the urethra, peritoneum, prevesical space, rectum, perineum, and ischiorectal fossa. By defining the extent of the disease, CT can guide selection of an optimal surgical drainage procedure. CT can be used effectively to monitor the treatment of prostatic abscess.
