Newly diagnosed right retroareolar breast cancer for staging. There is scattered fibroglandular tissue in both breasts.Mild parenchymal enhancement is noted bilaterally.The proven cancer in the right retroareolar region is seen as an enhancing mass measuring 2.0 x 1.4 x 1.4 cm. This measurement is inclusive of the nipple, which enhances and is included within the mass. There are a few enhancing foci extending 1.5 cm behind the nipple/mass. These are asymmetric compared to the left side. Including these foci, the total AP extent is 2.9 cm. No abnormal enhancement is seen in the left breast. No suspicious lymph nodes are identified in either axillary region. The largest right axillary node has a uniform mildly thickened cortex and maintains it's fatty hilum, findings more suggestive of a benign node.
Enhancing right breast mass includes the nipple and measures up to 2.0 cm. There are a few asymmetric foci immediately behind the mass for an AP extent of 2.9 cm. It is suspected that the largest measurement of the index lesion on the outside ultrasound (4.8 cm) may have been a measurement that included some normal retroareolar tissues given the smaller size on this study. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter.
