Developmental anomalies in the biliary tract occur mainly in the extra hepatic part and its vascular tree. The liver itself is usually free from major structural anomalies. Anomalies of the hepatic lobes are rare. Alterations in umbilical venous anatomy, especially the persistence of a right umbilical vein is considered rare. However, with the advent of ultrasonography and its use in prenatal diagnosis, its incidence has been increased. Here we report a case of hypoplasia of the right lobe of liver associated with a persistent right umbilical vein and discuss its clinical significance
