The most common causes of meconium peritonitis (MP) are ischemic lesions of the small bowel associated with intestinal obstruction, such as intestinal atresia, volvulus, intussusception, and meconium ileus. There have been only 4 reports of MP due to perforation of Meckel's diverticulum (MD) in the literature. In all cases, MP was diagnosed postnatally. We report a rare case of prenatally diagnosed MP, which was found to be due to a perforated MD at laparotomy. Our case suggests that perforation of MD should be included in the etiology of MP.
