Abstract
We present the case of a 79‐year‐old female with acute cholangitis and cholecystitis who presented with right upper quadrant pain. Thin‐collimation MR cholangiogram showed a filling defect measuring 1 cm, which was less prominent on single‐slab images. Endoscopy showed dynamic ballooning and collapsing of the ampulla of Vater, and a cholangiogram showed characteristic bulging at the distal common bile duct, which led to the diagnosis of choledochocele. It is important to differentiate choledochocele as a cause of filling defect of the lower common bile duct on the MR cholangiogram. J. Magn. Reson. Imaging 2007;26:1097–1100. © 2007 Wiley‐Liss, Inc.
