vitelline duct (cyst)
Cystic remnants of the omphalomesenteric duct may persist and be asymptomatic for long periods of time. The cysts are usually small, spherical mobile swellings connected to the ileum by a fibrous band which is a remnant of the obliterated vitelline duct.
Patients may present with acute volvulus or with an acute abdomen caused by infection of the cyst. Treatment is by excision.
