Other Imaging Findings

ERCP

ERCP has been regarded as the gold standard for diagnosis because it allows good visualization of the biliary system and the pancreas. Common findings include:

• Multiple segmental strictures
• Biliary dilatation: may be present in ~85% of cases
• Biliary diverticula
• Mural irregularities
• Distortion of the biliary tree due to associated cirrhosis

  This ERCP image shows several strictures of the anterior right hepatic duct alternating with areas of dilatation, thus producing a beaded appearance (arrows). Adapted from RadioGraphics http://pubs.rsna.org/doi/full/10.1148/radiographics.20.4.g00jl04959. Accessed on Dec 12, 2016.
