Hepatic calcification in an anicteric patient with biliary atresia after hepatic portoenterostomy

Hepatic calcification was found in an anicteric infant with biliary atresia after hepatic portoenterostomy. When she was 2 years of age, ultrasonography detected an echogenic structure with acoustic shadowing. Computerized tomography located it at the proximal portion of Segment 6 in the right lobe. Although both techniques failed to exhibit dilatation of the peripheral bile ducts, we believe intrahepatic cholelithiasis provides the most likely diagnosis. Although seven cases with biliary atresia were reported to have this complication, all of them were icteric when the diagnosis was confirmed. The patient should be carefully followed up since the succeeding stones may cause jaundice by obstructing the main duct.
