Infected congenital urethral diverticulum manifested as a scrotal mass in an adult male: case report and review of the literature.

Congenital anterior urethral diverticula in adult males are infrequent urological diseases. Clinical manifestation is frequently described with irritative and/or obstructive voiding symptoms or ventral bulging, but manifestation as a scrotal mass is extremely rare. Diagnostic imaging is useful to correctly diagnose the above in the majority of cases. We report the first case of a urethral diverticulum in which neither clinical nor instrumental evaluations were performed to confirm the diagnosis of urethral diverticulum. We stress the importance of a surgical approach in evaluating scrotal mass if diagnostic imaging cannot confirm an exact diagnosis. A complete review of the literature was also carried out.
