Biopsy proven invasive carcinoma in the left upper outer breast. Additionally, a stereotactic biopsy of the left breast at a central site showed ADH. There is scattered fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.At the site of known malignancy in the left upper outer breast, the Hydromark biopsy clip is well seen with mild surrounding enhancement measuring up to 8 mm. This probably represents a combination of the residua of the small mass and post biopsy change.In the left central breast at the location of the stereotactic biopsy with pathology resulting in focal ADH, there is focal enhancement with a few foci of enhancement projecting anterior to the biopsy site in a linear distribution. Overall AP extent is about 4 cm. There is also an area of lateral to medial enhancement corresponding to the biopsy track near this site. No abnormal enhancement is seen in the right breast. There are a few scattered enhancing foci in the right breast that appear similar to scattered enhancing foci on the left that are not at the areas described above.No abnormal enlarged lymph nodes are identified in either axillary region. Symmetric small nodes are present. Incidental note of a lipoma within the right serratus anterior is made.
1. Mild enhancement surrounding the biopsy clip of the known invasive cancer in the left upper outer breast measures up to 8 mm, and could relate to the residua of the mass and post biopsy change. 2. At the site of focal ADH from stereotactic biopsy, there is enhancement with a few linear distribution enhancing foci extending anteriorly. Excisional biopsy should be considered given this appearance and the ADH known from prior biopsy. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
