title: Antenatal rupture of a diverticular rectal duplication with neonatal perineal fistulization.
abstract: A cystic pelvic malformation was found in a fetus on antenatal sonography (US) at 26 weeks of gestational age that was no longer present 3 weeks later on control US. The male child presented at birth with a right-sided perineal mass that fistulized with meconial drainage. A radiopaque enema showed a low posterior rectal fistula filling a poorly delineated pouch. Surgery performed through a posterior sagittal approach allowed identification and closure of the fistula and pouch drainage. The diagnosis of a diverticular rectal duplication was considered, although no intestinal lining was observed macroscopically or histologically. The child's anorectal function was normal after a 20-month follow-up. Labeling of the malformation and embryological hypotheses are discussed since the case does not fulfill all the criteria of an intestinal duplication. Surgical techniques are discussed, with an emphasis on the sagittal posterior approach.
