PY - 2015 T2 - Fetology: Diagnosis and Management of the Fetal Patient, 2e AB - Key PointsCholedochal cyst refers to dilation of the common bile duct, with type I being the most common and the only prenatally diagnosed form.Prenatal diagnosis is based on the visualization of a single simple cystic structure near the gallbladder.Differential diagnosis includes hepatic, adrenal or renal cysts, duodenal duplication, and gallbladder duplication.There is no need to alter the management of pregnancy, nor the timing or mode of delivery, following the prenatal diagnosis of choledochal cyst.During the newborn period, detailed imaging of the biliary system is required to exclude biliary atresia, including radionuclide imaging.Definitive treatment requires surgical excision of the cyst, and long-term outcome is excellent.
