Gall bladder mass causing obstructive jaundice with possible fistulous tract

A locally infiltrating gall bladder mass had caused obstructive jaundice in this 50 year old lady. Contrast injection outlined a stricture at the level of the cystic duct (A: green arrow) and dilated intrahepatic ducts. Further contrast injection also outlined what appeared to be a fistulous tract adjacent to the CBD (B: green arrow). A 10F x 12 cm plastic stent was placed.
