Urethral diverticulum presenting as a scrotal mass in a paraplegic male: Report of a case and review of the literature.

Male urethral diverticula are rare and can be congenital or acquired. We report a case of acquired urethral diverticulum presenting as a scrotal mass in a paraplegic male. On physical examination, the scrotal mass mimicked a primary intrascrotal lesion. However, on retrograde urethrography, the correct diagnosis was made. The patient had a small incontinent spastic bladder with a history of prolonged catheterization. Eventually, the urethral diverticulum was excised including the affected segment of bulbous urethra. Pathologic examination revealed the diverticulum wall lined by granulation and chronic inflammatory tissue.
