Cholangiograms of clonorchiasis showing "too many intrahepatic ducts" signs. A. By percutaneous biliary drainage catheter (arrows) in a 58-year-old man, showing diffuse and uniform dilatation of the peripheral intrahepatic bile ducts. B. Endoscopic retrograde cholangiography in a 70-year-old man, with diffuse dilatation of the peripheral intrahepatic bile ducts, but no dilatation of the extrahepatic bile duct. C. Multiple, oval, small filling defects (arrows) within the dilated peripheral intrahepatic bile ducts, representing the flukes in a 55-year-old man. D. Magnetic resonance (MR) cholangiography in a 70-year-old man with diffuse dilatation of the peripheral intrahepatic bile ducts.
