Hepatic bruits in malignant liver tumors
The American Journal of Gastroenterology
|June 1, 1979
Summary
Hepatic bruits, or murmurs in the liver, can aid in diagnosing malignant liver tumors. Different tumor types produce distinct bruit patterns, offering valuable diagnostic clues.
Area of Science:
- Hepatology
- Medical Acoustics
- Oncology
Background:
- Hepatic bruits are infrequently reported in malignant liver tumors, particularly non-hepatocellular carcinoma types.
- Recent observations indicate the presence of hepatic bruits in various malignant liver conditions.
Purpose of the Study:
- To investigate the occurrence and characteristics of hepatic bruits in malignant liver tumors.
- To assess the diagnostic utility of hepatic bruits for liver malignancies.
Main Methods:
- Sound recordings were used to confirm the presence of hepatic bruits.
- Analysis of bruit characteristics in different types of malignant liver tumors, including hepatocellular carcinoma, cholangiocarcinoma, and metastatic liver carcinoma.
Main Results:
- Hepatocellular carcinoma cases exhibited continuous or continuous murmurs with late systolic accentuation.
- Cholangiocarcinoma presented with continuous murmurs and late systolic accentuation.
- Metastatic liver carcinoma showed a systolic murmur.
Conclusions:
- Hepatic bruits present with varied characteristics depending on the type of malignant liver tumor.
- These murmurs, caused by diverse mechanisms, can serve as a valuable diagnostic aid for hepatic tumors.
