Intrahepatic calculi in non-Asian patients were studied by sonography and computed tomography (CT). Three patients were studied by CT cholangiography also. In two cases, the calculi were consecutive to Caroli disease, and in two others, the biliary stones were formed proximal to a stenosis of a previous surgical anastomosis. Five patients spontaneously developed intrahepatic calculi. All sonograms were abnormal. Image specificity was good, even when bile ducts were not dilated, if appropriate technique allowed identification of a double-arc-shadow pattern. Sonography strongly suggested the diagnosis in eight patients and was nonspecific in only one. On CT, calculi had various densities, and they were not visible in two patients. CT cholangiography was not particularly helpful. Both examinations strongly underestimate the number of stones, and direct cholangiography remains indicated if surgery is planned.
