Hypertrophy of the caudate lobe is seen in a number of conditions, including:
- cirrhosis: most common
- Budd-Chiari syndrome
- primary sclerosing cholangitis (end stage)
- congenital hepatic fibrosis
- cavernous transformation of the portal vein
The caudate-right lobe ratio may be useful in quantifying caudate hypertrophy. A ratio of greater than 0.65 indicates a high likelihood of cirrhosis.
