41 year old female who was recalled from screening mammogram for left breast asymmetry. No family history of breast cancer. ML and laterally exaggerated CC views, as well as five spot compression views of the left breast were performed digitally and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is composed of scattered fibroglandular density, unchanged in pattern and distribution. There is redemonstration of a persistent mass in the upper outer left breast. This is felt more likely to represent a lymph node. ULTRASOUND: On physical examination, no palpable abnormality is identified.Targeted ultrasound of the left breast was performed for the mammographic area of concern. At the 2:00 position of the left breast, 12 cm from the nipple, there is a circumscribed, hypoechoic mass measuring 0.4 x 0.6 cm with suggestion of a fatty hilum with vascularity, suggesting a benign intramammary lymph node.
Hypoechoic mass a the 2:00 position of the left breast, likely representing a benign appearing intramammary lymph node. Follow up left breast mammogram, and possible ultrasound, in 6 months to assess stability.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
