[POSTERIOR PERIURETHRAL ABSCESSES DUE TO NEISSERIA GONORRHOEAE POSED DIAGNOSTIC DIFFICULTIES]

Posterior periurethral abscesses due to Neisseria gonorrhoeae are rare and thus difficult to diagnose and treat. We diagnosed this type of abscess using MRI and treated it conservatively.A 27-year-old man presented with perineal discomfort that had persisted for 1 week. Physical and CT findings indicated a prostate abscess, but MRI after admission revealed a multilocular mass in the posterior periurethra and polymerase chain reaction was positive for Neisseria gonorrhoeae. The posterior periurethral abscess was treated with Ceftriaxone and drainage via a cystostomy. This strategy improved the inflammation and CT confirmed the disappearance of the abscess from start of therapy in 43 days.
