CT Liver Normal Vs Cirrhosis Images | Irregular Margins, Splenomegaly, Portal Hypertension, Ascites
Liver Cirrhosis CT Features:
- Surface nodularity: Irregular liver margins
- Splenomegaly: Abnormal enlargement of spleen
- Heterogeneous liver appearance
- Regenerative nodules: Well-defined, round structures which appear slightly hyperdense on non-contrast CT
- Regenerative Nodules: Do not enhance during arterial phase, hence appearing hypodense during this phase.
- Siderotic nodules are a subtype of regenerative nodules that contain deposits of iron (hemosiderin) within them. These nodules occur in patients with cirrhosis who also have iron overload conditions, such as hemochromatosis or long-standing hemosiderosis.
- Regenerative nodules are not visible in portal venous phase
- Enlarged hilar space filled with fatty tissue, appearing hypodense
- Ascites: Hypodense fluid accumulated in the abdominal cavity
- Splenomegaly: Abnormal enlargement of spleen
- Ascites and Splenomegaly are usually associated with portal hypertension
- Caudate lobe hypertrophy: Abnormal enlargement of caudate lobe
- Portal Vein Enlargement (Diameter Less than 15 mm): Indicates portal hypertension
- Shrunken liver
- Portal Vein Thrombosis: Hypodense thrombus (clot) within the lumen of portal vein.
- Cavernous Transformation: Formation of enhancing serpentine, tubular collateral vessels adjacent to the portal vein
- Esophageal and Paraesophageal Collaterals: Appear as tubular or serpentine structures adjacent to the esophageal wall. They can be seen as enhancing vessels
- Enlarged Paraumbilical vein: Prominent paraumbilical vein connected to left portal vein branch
