title: Rectal duplication in an adult.
abstract: A case is presented of a 60-year-old white female with an asymptomatic rectal duplication. The patient was initially being worked up for a vague lower abdominal pain by her gastroenterologist. Subsequently, a pelvic CT scan showed a 3 x 5 cm mass perirectally and inferior to the levator ani muscle. Surgical consultation for further evaluation and excision was arranged. A mucosal-lined cystic structure was removed and found to be consistent with rectal duplication in cystic form.
