An unusual rectal duplication cyst

Abstract

Background: Rectal duplication cysts are rare gastrointestinal congenital duplicate cysts with various clinical presentations that require different management. Case presentation: We present a case of a lady with a double rectal duplicate cyst which was found incidentally on a follow-up CT abdomen and pelvis scan. The patient initially had a mucocele excision, and following that, she had a non-contrast CT abdomen and pelvis to investigate post-operative pain. The CT scan revealed a single rectal duplicate cyst. She had a posterior approach excision to have it removed, and only intra-operatively, she was found to have a double rectal duplicate cyst. She had them both removed via a midline incision running from the perineal pigmentation and extending until the coccyx. She had another follow-up CT which showed complete excision of the cysts.
