Fig. 7. Recurrent pyogenic cholangitis with Clonorchis sinensis infestation in 62-year-old male. A. Contrast-enhanced CT image shows diffuse dilatation of intrahepatic bile ducts, especially in peripheral portion of bile ducts (arrows). B. MR cholangiography shows marked peripheral intrahepatic bile duct dilatation without central bile duct dilatation. Multiple filling defects (arrowheads) noted within dilated bile ducts suggest presence of Clonorchis sinensis worms. CT = computed tomography, MR = magnetic resonance Fig. 7.
