Mammography, magnetic resonance imaging, and ultrasonogrphy are the three primary modalities employed in diagnostic imaging of the breasts.
1. What feature of this lesion suggests the diagnosis?
2. What BIRADS classification should be rendered?
Mediolateral oblique (MLO) and craniocaudal (CC) images of the right breast demonstrate a well-marginated mass, containing soft tissue and adipose components.
The identification of a well-marginated, encapsulated mass by mammography that contains both fat and soft tissue density is typical of a fibroadenolipoma (hamartoma).
Fat-containing breast lesions are considered benign; therefore, a fibroadenolipoma would be assigned a BIRADS 2 classification and routine mammographic screening in one year would continue.
