Thick slab magnetic resonance cholangiopancreatography (MRCP) image reveals mild dilatation of the entire common bile duct (CBD, arrow) with smooth distal tapering (short arrow). No filling defects are seen within the CBD The main pancreatic duct is of normal calibre (arrowhead)

A magnetic resonance cholangiography (MAGNETOM  Aera, Siemens, Erlangen, Germany) was performed that revealed mild dilatation of CBD and intrahepatic biliary radicles [Figure 1].
T-tube cholangiogram reveals lack of contrast opacification of the common hepatic duct and intrahepatic biliary radicles (arrowheads). Note the opacified CBD (arrow) and T-tube in situ (short arrow)

CBD with no opacification of IHBR suggestive of an inflammatory stricture at or just beyond the confluence [Figure 2]. Cholangioplasty was planned through the T-tube tract under conscious sedation.
Cholangiogram performed through percutaneous transhepatic biliary drainage catheter (PTBD catheter, arrow) following balloon dilatation of stricture reveals good opacification of the entire biliary tree

Cholangiography via the biliary catheter following the procedure revealed good opacification of the entire biliary tree [Figure 3].
