Ileocolic Intussusception in an Infant with Ileal Duplication Cyst as a Lead Point- A Case Report

Gastrointestinal duplication cysts are uncommon congenital malformations, with small intestine being the most common site, followed by colon and stomach. It can have variable presentations such as intestinal obstruction, bleeding, palpable mass, or rarely volvulus. Here, the authors report a case of intussusception in a two-year-old child, presented with complaints of bilious vomiting and abdominal distension for three days with X-ray features suggestive of bowel obstruction. Ultrasonography revealed intussusception with ileal duplication cyst as the lead point, which was confirmed on exploratory laparotomy. In a paediatric patient, enteric duplication cyst should be included in the differential diagnosis of a cystic lesion as the lead point in intussusception.
