53 year old female who was recalled from screening mammogram for 2 focal asymmetries in the left upper-outer quadrant. Mammogram: An ML view and four 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. Total of 3 subcentimeter asymmetries are noted in the anterior, mid and posterior depth in the lateral left breast. All 3 symmetries have benign morphology and a definite correlate is identified to the most anterior asymmetry. Ultrasound: Clustered cyst in the left breast 12:00 position measures 6 x 3 mm most likely corresponding to the anterior-most focal asymmetry. The other 2 mid and posterior depth asymmetries do not have an ultrasound correlate.
Clustered cyst identified in the left breast 12:00 position corresponding to the anterior most focal asymmetry. Benign morphology asymmetries in the lateral left breast without sonographic correlate for which six-month follow-up left unilateral diagnostic mammogram is recommended. No mammographic evidence of malignancy. Results and recommendation were discussed with the patient.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
