Helical computed tomography of the abdomen and pelvis after contrast shows the “target”-shaped area within 1 of the small-bowel loops, consistent with ileoileal intussusception (Figure 1). The patient underwent resection of the mass with an 8-cm margin from each side. The small bowel was then reconnected with a primary anastomosis. The patient was discharged home on postoperative day 4.

Pathologic examination of the specimen confirmed the diagnosis of inverted Meckel diverticulum with heterotopic pancreatic tissue and acute ischemic enteritis with serositis. Meckel diverticulum is the most common congenital anomaly of the gastrointestinal tract, occurring in 2% to 3% of the population1and often asymptomatic. Clinical symptoms arise from complications, which occur in 4.2% to 6.4% of those harboring the diverticulum.2,3The lifetime risk of complications is likely independent of age, although they are more common in men than women.4
