IMAGING FINDINGS:
The first post-contrast axial MRI image shows segmental nonmass enhancement involving the majority of the lateral left breast. The second post-contrast axial image, performed after 6 rounds of neo-adjuvant chemotherapy, demonstrates complete imaging response to therapy with decrease in size of the lesion and no remaining enhancement identified. WHY IT MATTERS:
Imaging Neoadjuvant Therapy Response in Breast Cancer (RSNA, 2017) IMAGING FINDINGS:
Post-contrast breast MRI image performed to assess extent of disease demonstrate the known biopsy proven malignancy (index lesion) in the left breast. There is a rim enhancing mass containing a biopsy clip in the inferior left breast at a posterior depth. The second post-contrast image demonstrates an irregular, enhancing mass in the central right breast at a middle depth. This is highly suspicious for contralateral disease. WHY IT MATTERS:

Bilateral MLO views demonstrate multiple round masses in both breasts. Many of the masses are calcified. WHY IT MATTERS:

Maximum intensity projection (MIP) image demonstrates moderate to marked symmetric background parenchymal enhancement bilaterally. WHY IT MATTERS: 1. Background parenchymal enhancement is reported on all breast MRI’s. The four categories are: a. Minimal b. Mild c. Moderate d. Marked 2. Background parenchymal enhancement is assessed as either symmetric or asymmetric. The MIP image gives a good overview of both breasts.

Sagittal MRI image demonstrates an irregular enhancing mass in the inferior right breast at a posterior depth. There is enhancement of the underlying pectoralis muscle consistent with pectoralis invasion. WHY IT MATTERS:

Axial post-contrast image demonstrates a heterogeneously enhancing mass involving the sternum. There are also enhancing lesions in several ribs. WHY IT MATTERS:

Mammographic views demonstrate a normal male tissue pattern in the right breast and moderate to marked gynecomastia in the left breast. WHY IT MATTERS:
