Congenital pelvic arteriovenous malformation: An unusual cause of rectal pain

The differential diagnosis of rectal pain is extensive, and etiologies range from common anorectal disorders to more complex pelvic floor dysfunctional syndromes. The authors present a case of a man with rectal pain secondary to a congenital pelvic arteriovenous malformation. These malformations are rare and, to the authors' knowledge, have not been reported in association with rectal pain.
