69-year-old female. Call back from screening for a focal asymmetry in the left outer breast. MAMMOGRAM: A standard ML view and three 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. The previously noted focal asymmetry in the left upper outer breast became less conspicuous on the spot compression views. LEFT BREAST ULTRASOUND: Targeted ultrasound of the left upper outer quadrant showed a 5 x 3 x 3 mm cyst at 2:00 o'clock, 6 to 10 cm from the nipple. An additional smaller cyst is seen at 1 o'clock.
Small benign cysts in the left breast. No mammographic or sonographic evidence of malignancy. The 2:00 cyst explains the asymmetry for which the patient was recalled. As long as the patient's physical examination remains normal, patient may return to annual bilateral screening mammogram. Results and recommendation were discussed with the patient.BIRADS: 2 - Benign finding.RECOMMENDATION: NS - Screening Mammogram.
