Two cases of hypoplasia of the right hepatic lobe with gallbladder ectopy, which were diagnosed by computed tomography, are reported here. In each patient, the left hepatic lobe was enlarged. The gallbladder was located in the inferior portion of the liver in one patient and immediately below the right hemidiaphragm in the other. No other anomalies complicated these two cases. It should be kept in mind that hepatic lobe anomalies may have associated ectopy of the gallbladder.
