Ultrasonographic-pathologic correlation of malignant hepatic masses

Area of Science:

• Medical Imaging
• Hepatology
• Oncology

Background:

• Identifying the origin of liver cancer aids in patient workup and reduces costs.
• Echographic (ultrasound) characteristics of hepatic masses are analyzed to determine their source.

Purpose of the Study:

• To correlate the echographic appearance of malignant liver masses with their pathologic or clinical diagnosis.
• To assess the specificity of ultrasound patterns in identifying the organ of origin for hepatic malignancies.

Main Methods:

• Retrospective analysis of 45 consecutive patients with malignant hepatic masses.
• Correlation of echographic findings (hyperechoic, hypoechoic) with confirmed diagnoses.
• Evaluation of sequential scans in patients undergoing chemotherapy.

Main Results:

• 31 patients had hyperechoic lesions, 25 of which were metastases from adenocarcinoma (colon, pancreas, unknown).
• No definitive correlation was found between ultrasound patterns and tumor source across diverse malignancy types.
• Sequential examinations in chemotherapy patients showed no alteration in echographic patterns.

Conclusions:

• The echographic appearance of hepatic malignancy lacks specificity for determining the organ of origin.
• Factors like homogeneity, vascularity, and desmoplastic response may influence ultrasound patterns more than cell type.
