Intestinal stenosis caused by perinatal intussusception in a full-term neonate.

Perinatal intussusception is rare, but can be seen in both premature and full-term neonates. The symptoms and signs are similar to those seen in necrotizing enterocolitis (NEC), causing the diagnosis of intussusception to be delayed. We report a case of intussusception that presented with features suggestive of NEC in a 3.4-kg, full-term female neonate. Diagnosis of intussusception was made with a plain abdominal x-ray and abdominal ultrasound. During surgery, an ileocolic intussusception with intestinal stenosis was found. Although intestinal stenosis and atresia are commonly found in premature infants, these entities can also occur in a full-term infant. Early diagnosis is needed to reduce the high morbidity and mortality in these infants.
