Entrapment neuropathy of the internal pudendal nerve. Report of two cases

Entrapment neuropathy of the internal pudendal nerve in the Alcock canal is a rare entity and literature on the subject is lacking. The pathogenesis of this disease is probably related to repeated microtraumatisms of the perineal region acting on the Alcock canal or dysmetabolic diseases favouring compression of the pudendal nerve inside the Alcock canal. In this article two new cases which have come to our attention are described and literature on the topic, with special regard to diagnosis and treatment, is reviewed.
