We report a rare case of prostatic abscess with Crohn's disease in a 21-yea
r-old male. Computed tomography showed a typical prostatic abscess. Moreove
r, filling of the abscess cavities with contrast medium was demonstrated af
ter micturition, which represented the rupturing of the abscess into the ur
ethra. Crohn's disease should be included in the differential diagnosis of
prostatic abscesses even in young males.
