Understand advances in prenatal imaging regarding the hepatobiliary system, including review of established normal patterns based on gestational age. Recognize prenatal sonographic and MRI findings of congenital hepatobiliary anomalies, which can generally be divided into primary lesions (including benign and malignant hepatic tumors and hepatobiliary malformations) and secondary manifestations of systemic problems (including transient and permanent sequelae of pregnancy-related disorders and genetic).

Background of prenatal hepatobiliary imaging Available techniques Normal findings by gestational age Primary hepatic masses Benign tumors Malignant tumors Cystic malformations Primary biliary malformations Choledochal cyst Gallbladder duplication Biliary atresia Secondary hepatic parenchymal abnormalities (calcifications, edema, enlargement, multifocal masses) Genetic/metabolic disorders Infectious disorders Metastatic disease Cardiovascular anomalies Secondary hepatic morphologic anomalies Diaphragmatic hernia Omphalocele Situs disorders Secondary biliary anomalies Obstruction by adjacent masses Dilation in multiple gut atresias Microgallbladder of cystic fibrosis Summary
