57-year-old female with intraductal papilloma with ADH and columnar cell change in right breast lesion, status post terminal duct excision in November 2015 presents for bilateral diagnostic mammogram. Mammogram: Three standard views of both breasts were performed digitally and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is composed of scattered fibroglandular density(BiRads Density Category B), unchanged in pattern and distribution. Multiple surgical clips identified in the right retroareolar region. An oval circumscribed benign morphology mass in the lower medial posterior right breast is increased since 2015, new from prior exams and persist on spot compression views. This most likely represents a proteinaceous cyst on MRI dated 2/17/2015No dominant mass, suspicious microcalcifications or areas of architectural distortion in either breast. Ultrasound: Targeted right lower inner quadrant ultrasound was performed. At 5:00 position there is a 8 x 4 mm circumscribed hypoechoic mass without peripheral blood flow most consistent with a simple cyst.
