Management of Hyperechoic Breast Lesions on Ultrasound

Characteristics of the Described Lesions

• The described lesions have multiple features consistent with BI-RADS 3 (probably benign) classification, including oval shape, parallel orientation to the skin, light posterior enhancement, and absence of vascularity, according to the American College of Radiology 1
• Lesions with oval shape, parallel orientation, and circumscribed margins have a low risk of malignancy, as recommended by the National Comprehensive Cancer Network 1, 2

Risk Assessment

• The probability of malignancy for lesions with these characteristics is less than 2%, based on guidelines from the American College of Radiology 1, 3

Management Algorithm

• Short-interval follow-up ultrasound is recommended for probably benign (BI-RADS 3) lesions, with an initial follow-up at 6 months and annual follow-up if stable, according to the American College of Radiology 1, 3
• Biopsy should be considered instead of follow-up if the mass is new or enlarging, in high-risk patients, or in patients with specific clinical conditions, as recommended by the American College of Radiology 1, 3, 4

Important Considerations

• Careful correlation between clinical and imaging findings is essential, and image-guided core biopsy should be performed if lesions increase in size during follow-up, according to the National Comprehensive Cancer Network 1, 5
• If lesions remain stable over 1-2 years, the patient can return to routine screening, as recommended by the National Comprehensive Cancer Network and other guidelines 5, 6

When to Consider Additional Imaging

• MRI is not indicated as the next step in evaluating probably benign findings, and diagnostic mammography may be appropriate depending on the patient's age and clinical context, according to the American College of Radiology 1, 4, 5, 7, 8
