Bile duct stenosis due to portal cavernomas: MR portography and MR cholangiopancreatography demonstration.
We report two cases of bile duct stenosis due to portal cavernomas. Smooth stenoses were seen arising from both walls of the common bile duct on magnetic resonance (MR) cholangiopancreatography. On contrast-enhanced MR portography, peribiliary tortuous vessels were evident, indicating portal cavernomas. MR imaging can evaluate the biliary tree and portal systems noninvasively and was useful for evaluating this condition.
