51 year old female who was recalled from screening mammogram for new mass in the left lower inner breast.. Mammogram: 2 ML views and two 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(BiRads Density Category B), unchanged in pattern and distribution. 14 mm circumscribed oval hyperdense mass in the left lower inner quadrant posterior depth persist on spot compression views. No associated calcifications. Multiple other benign morphology masses elsewhere are stable.Ultrasound: Targeted left lower inner quadrant ultrasound was performed. A small 5 x 4 mm simple cyst was identified in the left breast 8:00 position, 10 cm from the nipple. This probably is an incidental finding and might not correspond to the 14 mm circumscribed oval benign morphology mass in the left breast on the mammogram.
High probability benign morphology 14 mm circumscribed oval mass in the left breast lower inner quadrant without definite sonographic correlate needs further evaluation with left unilateral diagnostic mammogram in 6 months to confirm stability.Incidentally noted 5 mm simple cyst in the left breast on ultrasound.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
