Abstract
This paper describes a case of hypoplasia of the right hepatic lobe, a very rare variant of the liver. A 65-year-old male was admitted to the hospital because of fever, jaundice and abdominal pain. Ultrasonography of the abdomen and ERCP revealed choledocholith, and hypoplasia of the right hepatic lobe was suggested by CT scan. Choledocholithotomy was performed and a T-shaped drainage tube was left in the choledochus. Though hypoplasia of the right hepatic lobe should be distinguished from atrophy of the right hepatic lobe in this case, a diagnosis of hypoplasia was made in consideration of operative findings, histology of the liver specimen, intraoperative T-tube cholangiography and postoperative angiography. As of 6 months after the operation, the patient is making good progress. Eleven cases of hypoplasia of the right hepatic lobe have been reported and all of them were accompanied with malposition of the gallbladder. In this case the gallbladder was found at slightly high position and the same congenital anomalies as recent cases were suggested.
