An 11-year-old girl presented with an extremely rare complication of Meckel's diverticulum. The patient presented with complaints of abdominal distension, abdominal pain, decreased appetite, and non-bilious vomiting for 20 days with a history of mass protruding per rectum. Examination revealed a distended abdomen and prolapsing bowel loops during rectal examination, resembling intussusception. Radiological findings indicated intestinal obstruction. Surgical exploration revealed Meckel's diverticulum invading the rectum, accompanied by dense inter-bowel adhesions. The patient underwent resection of Meckel’s diverticulum and repair of the rectal rent. This case highlights the rarity of Meckel's diverticulum fistulating into the rectum.
