Report of a rare case of abscess in both cavernous bodies. Its peculiarity is based on the location, the bilateral nature and the absence of a clear causative factor, although it was probably related of a local septic focus (rectal or prostatic). Diagnosis was established with CAT because of the primarily posterior location and the significant peripheral inflammatory reaction. The patient was treated successful with a vigorous antibiotic therapy and open drainage from both cavernous bodies with no development of sequelae such as fibrosis and penial incurvation or impotence.
