Ultrasound
There are no specific findings on ultrasound for hepatitis C virus. Nonetheless, ultrasound may show findings consistent with complications induced by the disease, namely cirrhosis and hepatocellular carcinoma.
Ultrasound Findings of Cirrhosis
Ultrasound findings are as follows:
- Hepatomegaly
- Changes in liver contour
- Nodularity
- Increase in echogenecity from focal fatty infiltration
- Vascular changes:
- Flow across both portal and systemic circulation increases
- Resistive index increases in end stage liver disease
- Vessels appear elongated and tortuous, called "corkscrewing" of the vessels
- Doppler ultrasound may show spontaneous shunts
- Splenomegaly and collaterals from portal hypertension may be noted.

Ultrasound Findings of Hepatocellular Carcinoma[1][2]
- Presence of dysplastic nodule(s)
- Hypoechoic lesion (small) or mixed echogenicity (large)
- Evidence of portal vein, hepatic vein, and inferior vena cava invasions
