Abdominal cystic mass in infancy--in utero perforated Meckel's diverticulum?

Meckel's diverticulum occurs in 2% of the population. Of these, 4% may present as intestinal bleeding, intussusception, diverticulitis, volvulus, or perforation at any age, including neonates. We describe a 3-month-old baby whose giant Meckel's diverticulum had probably perforated in utero, leading to the formation of a large intra-abdominal pseudocyst.
