Cholelithiasis in a 9-Year-old Girl Presenting with Abdominal Pain

concrement at level ’I’ 12-L 1. Oral cholecystography was normal; no stones were visualized. Ultrasonography, however, revealed a stone and a septum in the gallbladder (Fig. 1). A cholecystectomy was performed and a black, sharp-edged stone was removed, measuring from 5X4X4 mm. On chemical analysis the stone consisted mainly of bilirubin, calcium, and phosphate. On microscopy, the gallbladder had a normal structure without signs of cholecystitis. Two years after the operation the girl had suffered no episodes of abdominal pain, and there were no signs of hemolytic disease. No new stones could be demonstrated.
