73 year old female who was recalled from outside screening mammogram for left breast asymmetry. MAMMOGRAM: An ML view and two spot compression views of both breasts 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. Within the left breast, 12 o'clock position, the previously visualized asymmetry partially disperses on spot compression imaging, suggesting superimposition of fibroglandular tissues.Within the right breast, upper outer quadrant, there is a new 0.8-cm mass which persists on spot compression imaging.ULTRASOUND: A targeted left ultrasound was performed for the mammographic area of concern. A dense band of fibroglandular tissue is noted. There is no solid or cystic mass identified.A targeted right ultrasound was subsequently performed for the mammographic area of concern. At the 10 o'clock position of the right breast, 5 cm from the nipple, there is a well-circumscribed anechoic cyst mild posterior acoustic enhancement measuring 0.5 x 0.4 x 0.5 cm, likely corresponding to the finding on mammogram.
Dense fibroglandular tissue in the upper central left breast corresponding to the asymmetry on mammogram. Right simple breast cyst. No mammographic evidence of malignancy. As long as the patient's physical examination remains normal, bilateral screening mammogram is recommended annually. Results and recommendation were discussed with the patient.BIRADS: 2 - Benign finding.RECOMMENDATION: NS - Screening Mammogram.
