Pyloric atresia is a rare malformation of the alimentary tract. Fetal gastric dilatation and polihydramnios are the main prenatal sonographic findings. In 20% of the cases epidermolysis bullosa is associated. ⋯ A huge gastric dilatation and a gasless intestine will be apparent in the abdominal plain x-ray. Pyloric atresia is a surgically resolvable malformation. We present herein three patients with this infrequent anomaly.
