title: Antenatal diagnosis of biliary atresia (noncorrectable cyst type): a case report.
abstract: At 32 weeks of gestation a cystic mass was identified in the hepatic hilum of a fetus by maternal sonography. Laparotomy was performed at 39 days of life after a diagnosis of correctable type of biliary atresia (Type I). A cystically dilated extrahepatic duct, in which the proximal and distal sides of the common bile duct were occluded (Type III with cyst, noncorrectable type), was identified by operative cholangiography. A standard Kasai operation was performed, and 1 year after operation the patient was doing well and was jaundice-free. From this experience in routine maternal sonography, a cystic mass in the hepatic hilum may also suggest Type III biliary atresia with a cyst.
