A rare case of a gastrointestinal cystic duplication in a 7-day-old infant
is described. The duplication diagnosed antenataly at 25 weeks of gestation
was found during surgery to be separated from the gastrointestinal tract,
hanging on a vascular pedicle, with no connection to the mesentery. The dup
lication was excised, and postoperative follow-up of 14 months was uneventf
ul. The possible pathogenesis of this malformation is discussed. Copyright
