Figure 1: Choledocholithiasis: discordant findings between ultrasound and MRCP for the main biliary tract. A: Ultrasound: the choledocho is dilated (maximum diameter 11mm) but no signs suggestive for stones are detected. B: CPRM confirms the diagnosis of choledocho ectasia and shows two round “filling defects” in the distal tract of the choledocho suggestive for stones.
