Imaging of autoimmune biliary disease

Area of Science:

• Hepatology
• Radiology
• Immunology

Background:

• Autoimmune biliary diseases are often asymptomatic initially.
• They can progress to cholestasis, ductopenia, portal hypertension, cirrhosis, and liver failure.
• Key conditions include primary biliary cirrhosis, primary sclerosing cholangitis, and IgG4-associated cholangitis.

Purpose of the Study:

• To review the current literature on autoimmune biliary diseases.
• To emphasize the role of radiological findings in diagnosis and management.
• To highlight imaging's utility in monitoring disease progression and complications.

Main Methods:

• Literature review of autoimmune biliary diseases.
• Focus on radiological findings and diagnostic considerations.
• Analysis of imaging's role in disease monitoring and complication assessment.

Main Results:

• Imaging is essential for monitoring disease progression and assessing complications.
• Radiological findings can suggest or corroborate diagnoses of primary sclerosing cholangitis and IgG4-associated cholangitis.
• Imaging aids in screening for hepatobiliary malignancies associated with these diseases.

Conclusions:

• Accurate diagnosis and monitoring of autoimmune biliary diseases are critical.
• Imaging is indispensable for managing primary biliary cirrhosis, primary sclerosing cholangitis, and IgG4-associated cholangitis.
• Radiological assessment supports disease-specific workups and surveillance.
