Cystic lymphangioma associated with enteric duplication as a cause of recurrent vomiting

We describe a case report of a 6-year-old boy with a 4-year history of recurrent vomiting with a cyclical vomiting pattern. Although initially labelled with and treated for Cyclical Vomiting Syndrome the cause was subsequently found to be an enteric duplication associated with cystic lymphangioma, an association not previously described.
