Cystic biliary atresia (Type III) is uncommon and it may be difficult to differentiate this from a choledochal cyst, an entity that has a very different management and prognosis. This report shows the percutaneous cholangiographic findings in two cases of Type III biliary atresia with a non-communicating cyst, with ultrasound and clinical correlation. These findings are helpful in the diagnosis and management of patients with this condition.
