Ultrasound in the evaluation of solid breast masses

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Background:

• Distinguishing benign from malignant breast masses is crucial for effective patient management.
• Ultrasound is a primary imaging modality for breast lesion evaluation.
• Specific imaging features can aid in differentiating breast mass types.

Purpose of the Study:

• To identify key ultrasound image characteristics differentiating benign and malignant breast masses.
• To determine the frequency of specific imaging features in common breast masses.

Main Methods:

• Cross-tabulation and analysis of ultrasound and radiographic features.
• Evaluation of 31 benign and 41 malignant breast masses.
• Comparison of imaging characteristics between ductal carcinoma and fibroadenoma.

Main Results:

• Malignant ductal carcinoma frequently presented with jagged walls (88%) and posterior shadowing (97%).
• Benign fibroadenomas commonly exhibited smooth walls (94%) and homogeneous internal echoes (89%).
• Attenuation effects and echo patterns varied between malignant and benign lesions.

Conclusions:

• Ultrasound features like wall regularity and shadowing are highly indicative of breast mass malignancy.
• Smooth walls and homogeneous echoes suggest a benign fibroadenoma.
• These characteristic differences aid in the diagnostic accuracy of breast ultrasound.
