A unique case of inverted Meckel’s diverticulum presented as an adult intussusception: a case report

Although Meckel’s diverticulum (MD) is a relatively common asymptomatic gastrointestinal anomaly, an inverted MD is a rare entity that is challenging to diagnose prior to surgery and presents usually in the pediatric population with bleeding, anemia and abdominal pain. The most frequent adult presentation in non-inverted MD is intestinal obstruction, whereas bleeding and anemia are the most typical presenting complaints in inverted MD. Here, we report our experience with an adult female patient, who presented with 5 days duration of abdominal pain, nausea and vomiting. Imaging revealed signs of small bowel obstruction with bowel wall thickening in the terminal ileum and a double target appearance. This case describes a rare cause of adult intestinal intussusception because of inverted MD, which was successfully managed with surgery. The final pathology report confirms the diagnosis.
