Omphalomesenteric duct cyst as a content of omphalocele.

A rare occurrence of an omphalomesenteric duct cyst in an exomphalos minor sac is reported herein. The noteworthy points in this case were an unusual presentation of the rarest variety of umbilical cord cyst. The tapering intra-abdominal end of the cyst was found to be attached to the ileal mesentry, thereby simulating a herniating mesenteric cyst till the histolopathological report resolved the issue.
