Abstract
Reports of primary intrahepatic cholesterol stone have been increased in recent years. However, cases of early age onset were found only a few. We experienced an early age onset case of primary intrahepatic cholesterol stone.
The patient was 23 years old man w ho had right hypochondralgie and liver function disorder. Ultrasonogram showed small high echo lesion in the gallbladder, and also showed high echo spot and acoustic shadow in right posterior hepatic lobe. Under a diagnosis of cholelithiasis and intrahepatic stone, operation was performed. Many minute stones were found in right posteriorinferior branch at operative cholangiography.
Cholecystectomy was done, and postoperatively we tried endoscopic lithotomy through sinus tract of the T-tube. However lithotomy was not successful. Two months later from the first operation, the right posterior lobectomy was performed. In the resected specimen, minute cholesterol stones were confirmed in the right posterior-inferior branch. The stones contained 98% of cholesterol according to the result of analysis of stone by infared spectum.
