50-year-old female. Recall from screening for a small mass in the right lower inner quadrant. MAMMOGRAM: An ML view and two spot compression views of the right 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. The circumscribed small round mass in the lower inner quadrant of the right breast persisted on spot compression views.RIGHT BREAST ULTRASOUND: Targeted ultrasound of the right lower inner quadrant showed an anechoic 3 x 3 mm focus without internal vascularity in the retroareolar region at 5:00 o'clock, most likely a cyst and corresponding to the mass seen on mammography.
Small mass in the right lower inner quadrant on mammography most likely corresponds to a cyst. Ultrasound guided aspiration is recommended to confirm that it is a cyst. The results and recommendations were discussed with the patient at the completion of the exam, and the patient elected to schedule the ultrasound-guided aspiration.BIRADS: 3 - Probably benign finding.RECOMMENDATION: H - Percutaneous Biopsy/Aspiration.
