(A) Conventional T-tube cholangiogram under fluoroscopy confirmed a stricture (arrow) but the leak was not seen. (B) Rotated image (for comparative purposes) of a CEUS cholangiogram administered via a T-tube (thick arrow), inserted post cholecystectomy. Ultrasound contrast delineates the common bile duct including a point of stricture (thin arrow) and a contrast extravasation leak (arrowhead)
