Abstract

Intestinal duplications are rare congenital anomalies that can occur anywhere in the gastrointestinal tract. They are most commonly located in the ileum and are usually detected in infancy or early childhood. Duplicated segments are usually firmly attached to and sometimes communicate with the normal gastrointestinal tract. Rarely, intestinal duplications are completely isolated, thus not associated at all with any part of the gastrointestinal tract. Such duplications do not share a common blood supply with the adjacent normal intestinal segment, unlike the usual form of duplication, but rather have a separate vascular pedicle. Reports of completely isolated duplication cysts in adults are extremely rare; we found only five such reports in the English-language medical literature. Here, we report a case of a completely isolated duplication cyst 12 cm long in an adult female. The cyst had no connection to any part of the intestinal tract and had a dedicated vascular pedicle.

Core tip: Intestinal duplications are rare congenital anomalies generally detected in infancy or early childhood. Duplicated segments are usually firmly attached to and sometimes communicate with the gastrointestinal tract. Rarely, intestinal duplications are completely isolated, thus not associated at all with the normal gastrointestinal tract. Such duplications do not share a common blood supply with the adjacent normal intestine, unlike the usual type of duplication. Reports on completely isolated duplication cysts in adults are extremely rare; we found only five in the English-language literature. Here, we report a case of a completely isolated duplication cyst mimicking an ovarian cyst in an adult female.
