А case report of the complex biliary and portal developmental anomaly designated previously in literature as "a right-sided round ligament and a false left-sided gallbladder" is presented in the paper. The embryogenesis disturbance at the 7-8th week results in regression of the left-sided umbilical vein instead of right-sided one. Accordingly, the round ligament joins to the VIII segmental branch of the portal vein, but not to the Rex sinus. The gallbladder is present at the normal position but to the left of the round ligament, so it is often erroneously described as dystopic. This anomaly is strongly associated with an abnormal portal venous and biliary branching. It is important to have all the information about it for the planning the interventional or surgical procedures. Therefore, the radiologists must pay attention to this anomaly.
