Summary
A bright liver echotexture in chronic hepatitis C patients correlates with fatty infiltration. A hypoechoic area near the liver hilus is a key sonographic sign of this fatty infiltration.
Area of Science:
- Hepatology
- Medical Imaging
- Gastroenterology
Background:
- Chronic hepatitis C often presents with altered liver echotexture.
- Understanding sonographic findings in relation to histology is crucial for non-cirrhotic patients.
Purpose of the Study:
- To investigate the correlation between liver sonographic echotexture and histological findings.
- Specifically in patients with chronic hepatitis C without cirrhosis.
Main Methods:
- High-resolution ultrasound evaluated 68 chronic hepatitis C patients and 70 controls.
- Histological specimens were obtained concurrently for grading and staging.
- Histological Activity Index was used for assessment.
Main Results:
- A bright liver echotexture was observed in 38% of chronic hepatitis C patients, correlating with fatty infiltration.
- No significant correlation was found between echotexture and other histological activity index parameters.
- Hypoechoic areas near the liver hilus were present in 92% of patients with bright echotexture.
Conclusions:
- Bright liver echotexture in chronic hepatitis C is primarily linked to fatty infiltration.
- A hypoechoic lesion adjacent to the liver hilus serves as a sonographic indicator of fatty infiltration.
- This finding may suggest areas of reduced fat or increased fibrosis due to vascular differences.
