Intrahepatic hyperechoic lesions with acoustic shadows could be stones or nonspecific calcifications. To verity this, 9 patients with hepatic parenchymal calcifications were compared with 40 patients with intrahepatic stones. A set of criteria are proposed for the diagnosis of intrahepatic stones: (A) dilated intrahepatic duct; (B) pneumobilia; or (C) 2 or more of the following: (1) common hepatic duct more than 6 mm in diameter, (2) multiple lesions in one lobe, (3) left lobe involvement, and (4) elevated serum alkaline phosphatase. The sensitivity, specificity, and overall accuracy were 97.5%, 88.9%, and 95.9, respectively. The criteria help in the selection of patients for evaluation of intrahepatic stones.
