CHACON-GARITA, Lindsay  e  GARCIA-ARIAS, Fabián. Persistence of the omphalomesenteric duct. Acta méd. costarric [online]. 2017, vol.59, n.4, pp.158-160. ISSN 0001-6002.

The persistence of the omphalomesenteric duct and the urachus are the most frequent congenital malformations of the umbilical region. A failure in the regression of the omphalomesenteric duct determines the origin of a wide spectrum of abnormalities related to the abdominal wall, including the persistence of the omphalomesenteric duct.

We present the case of a 10-year-old patient with complete and permeable persistence of the omphalomesenteric duct, what makes the case unusual is its presentation with acute abdomen, reason for which it was initially diagnosed as acute appendicitis. The importance of this type of case is emphasized by its multiple clinical manifestations and the complications that it entails
