Inguinal herniation of vitelline duct remnant

摘要

Meckel's diverticulum and vitelline duct cysts result from incomplete obliteration of the vitelline or omphalomesenteric duct in utero. We report a case of an infant with a vitelline duct remnant within an inguinal hernia sac, incidentally encountered during inguinal herniorrhaphy and orchidopexy. The cystic remnant had a fibrous connection to the umbilical ring, suggesting an auto-amputated Meckel's diverticulum with persistent residual cord to the umbilicus. This rare anomaly has the potential to cause serious complications by providing an intra-abdominal band with the risk for volvulus or internal herniation of small intestine.
