Adult intussusception caused by inverted Meckel diverticulum is infrequent but important clinical entity, presenting with nonspecific symptoms. It may be observed in any age. We report a 26-year-old male patient with intussusception, who was examined several times for abdominal pain accompanied with nausea and vomiting. Basic diagnostics were inconclusive, so the patient was discharged each time with conservative therapy. After the last episode, CT scan showed suspicious intussusception, so the patient was admitted to general surgery ward. The next day there was a complete regression of all difficulties, and he was free of them in the month ahead. Finally, NMR enterography verified the presence of intussusception, and the operative procedure was performed. At laparotomy, ileo-ileal double intussusception was observed and the affected segment was resected with T-T anastomosis. Histopathological examination demonstrated an inverted Meckel diverticulum, measuring 8cm, with ectopic gastric antral type mucosa and ectopic pancreatic tissue. Postoperatively, the patient made an uneventful recovery.
