Meconium peritonitis is a sterile inflammatory reaction to the meconium in the fetal abdomen as a result from the intestinalperforation. With some characteristic signs of meconium peritonitis, the prenatal diagnosis has been increasing. In mostcases, the meconium peritonitis may resolve spontaneously. But intussusception is a surgical emergency. Nonetheless, thediagnosis is hard to make prenatally due to lack of the experience about this disease in utero. We report a case which ismanaged under the diagnosis of meconium peritonitis and intussusception has been confirmed by the surgical findings.
