Within the distal cystic duct stump, there is a rounded filling defect showing low attenuation that is highly concerning for residual cystic duct stone; hematoma would be expected to have a more amorphous shape and elevated attenuation. Otherwise, this study shows only expected post cholecystectomy appearance, and no other filling defect in the biliary tree.

MRCP confirms with better resolution the filling defects in the cystic duct, thought to be related to residual stones.
