Summary
Breast metastases from various cancers show distinct patterns on mammography. Understanding these imaging features aids in diagnosing secondary breast cancer, differentiating it from primary tumors.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Breast metastases are secondary malignancies in the breast, distinct from primary breast cancer.
- Mammographic evaluation is crucial for identifying and characterizing breast lesions.
Purpose of the Study:
- To illustrate the mammographic appearances of breast metastases.
- To correlate imaging findings with histological confirmation.
Main Methods:
- Retrospective review of 43 cases with histologically confirmed breast metastases.
- Analysis of mammographic features based on the route of spread (hematogenous, lymphogenous, systemic hematological).
Main Results:
- Hematogenous metastases typically present as sharply demarcated foci.
- Lymphogenous metastases manifest as skin thickening and reticular changes in subcutaneous and glandular tissues.
- Metastases from systemic hematological diseases can appear as nodular or diffuse lesions.
Conclusions:
- Mammographic patterns of breast metastases vary depending on the origin and spread pattern.
- Distinct imaging features can help differentiate metastatic disease from primary breast cancer.
