During normal embryonal development, the omphalomesenteric duct, or vitelline duct serves as a primitive connection between the midgut and the yolk sac. Normally, the omphalomesenteric duct undergoes obliteration during the 5th-9th week of gestation. Failure of obliteration results in a persistent omphalomesenteric duct. Different anatomic and morphologic variants of vitelline duct anomalies exist. The most common form is known as a Meckel’s diverticulum, an entity that is usually diagnosed in the pediatric population. A rare form of this developmental anomaly is the presence of a persistent omphalomesenteric duct cyst. While this is an uncommon occurrence in the pediatric population, it is extremely rare in the adult population. In this report, we present a 24-year old adult male with abdominal pain and CT-findings of a cystic structure connecting to his umbilicus. This structure, later diagnosed as an omphalomesenteric duct cyst, was successfully and safely treated by laparoscopic resection.
