Alcoholic hepatitis CT

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, decreased liver attenuation, liver to spleen attenuation ratio and increased 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][5]
- Splenomegaly, defined as spleen dimension ≥ 13 cm
- Degree of Ascites; mild , moderate or severe
- 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 [6]
- Liver length to mid clavicular line
- Decreased Liver attenuation around portal system
- Liver to spleen attenuation ratio > 10 hounsfield units is suggestive of hepatic steatosis [7]
- Increased Liver heterogenecity
