Congenital atresia of the portal vein and extrahepatic portocaval shunt associated with benign neonatal hemangiomatosis, congenital adrenal hyperplasia, and atrial septal defect

A rare case of congenital atresia of the portal vein and ductus venosus, extrahepatic portocaval shunt, benign neonatal hemangiomatosis, congenital adrenal hyperplasia, and an atrial septal defect is reported. Twenty-two cases of congenital extrahepatic end-to-side shunts have been described before. Although additional anomalies are common in this type of shunt, hemangiomatosis has been described only once. Adrenal hyperplasia has never been reported in this anomaly.
