Giant Presacral Tailgut Cyst Mimicking Rectal Duplication in a Girl: Report of a Pediatric Case

Abstract

Tailgut cyst, or retrorectal cystic hamartoma, is a rare congenital lesion found in the presacral space. The lession has been infrequently reported in medical literature. It is most common in middle-aged women and is rare in children. We report a case of a tailgut cyst mimicking a rectal duplication in an 8-year-old child. Excision and histological examination of the mass confirmed the tailgut cyst.
