title: [Testicular torsion in testicular duplication. Kasuistik und Literaturubersicht].
abstract: We describe a case of testicular duplication presenting as torsion of the supernumerary distal testis in a 14-year-old boy. Clinical examination showed an unclear mass above the left testis; intraoperatively, the supernumerary testis was linked to the regular testis by a common epididymis and shared a common vas with it. The distal testis was resected due to severe hemorrhagic damage. This condition represents the result of transversal division of the wolffian duct during organogenesis. Review of the literature revealed that testicular torsion, testicular tumor, unclear scrotal masses, or continuing potentia generandi after bilateral vasectomy were the reasons that polyorchidism was detected.
