Inverted Meckel's diverticulitis manifesting as intussusception: unusual case of intestinal obstruction in adults

Meckel's diverticulum can manifest with various complications such as obstruction, intussusception, inflammation or diverticulitis, perforation, haemorrhage and fistula, and commonly manifests in children. Adult intussusception due to inverted Meckel's diverticulum is an uncommon aetiology of intestinal obstruction but should be suspected in individuals. Imaging such as contrast-enhanced computed tomography aids in the diagnosis but it is not confirmatory to diagnose inverted Meckel's diverticulum as a leading point. Resection of the intussusception segment is the definitive treatment. We present the case of a young man who presented in emergency with complaints of intestinal obstruction and ileo-ileal intussusception was the aetiology of for the same diagnosed on contrast-enhanced computed tomography of the abdomen. On exploration we discovered an inverted Meckel's diverticulum to be the leading point for intussusception.
