Hypoplastic right hepatic lobe with retrohepatic gallbladder complicated by hepatolithiasis and liver abscess: A case report

A 37-year-old man with fever, jaundice, severe right upper quadrant abdominal pain and impending septic shock was pre-operativly diagnosed to have hypoplastic right lobe liver with retrohepatic gallbladder, left hepatolithiasis and liver abscess by computed tomography. An urgent operation with cholecystectomy, choledocholithotomy, operative choledochoscopy and T-tube drainage was performed. Postoperative cholangiograms depicted multiple residual stones behind the sharply angualted biliary strictures in the medial branches of the left intrahepatic duct, which could not be eradicated by biliary dilatation via the T-tube tract. The left hepatolithiasis might be coincidental, or secondary to the congenital anomaly of the liver, because of the distorted biliary architecture, and the hypoplastic right lobe liver was associated not only with the retrohepatic gallbladder, but also with the much more complicated left biliary strictures and the hepatolithiasis behind them.
