BACKGROUND: I evaluated the computed tomographic (CT) features of nine pathologically proven cases of @entity201 in the extrahepatic bile duct associated with @entity14007 . METHODS: CT scans of nine pathologically proven @entity201 associated with @entity14007 were reviewed retrospectively. CT scans were analyzed for the following parameters: @entity5 (detection, location, gross morphologic type, contrast enhancement), intrahepatic bile duct (dilatation, pattern of dilatation), common bile duct (dilatation, @entity2440 worms), @entity1085 ( @entity32 , @entity2441 worms), invasion of the contiguous viscera (pancreas, duodenum, liver), @entity194 , and @entity3329 and @entity3 . RESULTS: CT depicted the level and cause of obstruction in all nine @entity1 (100%). Contrast enhancement of the @entity5 relative to the liver parenchyma showed isoattenuation in five @entity5 (55%) and hyperattenuation in four @entity5 (44%). Severe, uniform dilatation of the intrahepatic bile duct was identified in six @entity1 (67%) and central dilatation was seen in two @entity1 (22%). No evidence of dilatation of the intrahepatic bile duct was seen in one patent (11%). Most @entity5 were located in the proximal third of the extrahepatic bile duct ( n = 7, 78%). Male preponderance was found ( n = 8, 89%). CONCLUSION: @entity201 associated with @entity14007 was located predominantly in the proximal third of the extrahepatic bile duct and detected more readily than nonclonorchiasis-associated @entity201 .
