Computed axial tomography in the early diagnosis of prostatic abscess.

An extensive, multiloculated prostatic abscess due to Staphylococcus aureus developed in a patient with mycosis fungoides. The clinical symptoms and signs were largely masked by prior antibiotic therapy until after urethral instrumentations. Computed axial tomographic scanning of the pelvis confirmed the clinical diagnosis and demonstrated the resolution of the prostatic abscess following antibiotic therapy. This is the first reported case of a prostatic abscess diagnosed by computed axial tomographic scanning.
