Final answer:

The BIRADS US lexicon for solid breast masses includes shape, orientation, margin, echo pattern, and posterior features. These descriptors aid in the accurate classification and management of breast lesions.

Step-by-step explanation:

The BIRADS US lexicon for describing solid breast masses includes several descriptors. Five key descriptors are:

  • Shape - Description of the mass's contour, such as oval, round, or irregular.
  • Orientation - The alignment of the mass in relation to the skin line and pectoral tissues, e.g., parallel or not parallel.
  • Margin - The distinctness of the mass's borders, which can range from well-circumscribed to indistinct or spiculated.
  • Echo pattern - The internal echo characteristics, which can be homogeneous, heterogeneous, or demonstrating specific features like calcifications.
  • Posterior features - Changes behind the mass on ultrasound, such as posterior acoustic shadowing or enhancement.

Accurate description using these terms can help in the assessment and management of breast lesions and contribute to a more precise BIRADS categorization.
