Overview
CT scan is usually performed among patients with Alcoholic Hepatitis to exclude other abnormalities including neoplasm, biliary obstruction or infiltrative liver disease.CT scan can predict severity and outcome of Alcoholic Hepatitis by presence of splenomegaly, ascites, varices, liver length to mid clavicular line, liver attenuation, spleen attenuation, and liver heterogenecity.
CT
- CT scan is usually performed among patients with Alcoholic Hepatitis to exclude other abnormalities including neoplasm, biliary obstruction or infiltrative liver disease.[1][2]
- CT scan can predict severity and outcome of Alcoholic Hepatitis by presence of the following findings:[3][4]
- Splenomegaly, defined as spleen dimension ≥ 13 cm
- Ascites
- Varices; defined as moderate if esophageal varices < 3 mm or paraesophageal varices < 5 mm, severe varices defined as esophageal varices > 3 mm or paraesophageal varices > 5 mm [5]
- Liver length to mid clavicular line
- Liver attenuation, measured approximately 5 cm2 regions of interest in the right, central, and left liver at the level of the portal vein
- Spleen attenuation, measured approximately 5 cm2 regions of interest in the center of spleen
- Liver heterogenecity, mild heterogenecity considered as if 1 to 50% of hepatic parenchyma was heterogenous, more than 50% of heterogenous area considered moderate to severeheterogenecity
