Gastrointestinal duplications are rare congenital malformations that may vary greatly in presentation, size, location and symptoms. They can present as solid/cystic tumors, intussusception, perforation or bleeding. A high index of suspicion is needed in all such cases. Radiologic studies may not be enough for a diagnosis. We present a case of ileal duplication cyst in a 2 month old baby who presented with features of abdominal obstruction. Suspecting it to be an infected mesenteric cyst from radiological studies, surgical excision with anastomosis of the ileal segment was done. The histopathological examination of the resected specimen diagnosed it as an enteric duplication cyst.
