42 year old female who was recalled from screening mammogram for left breast asymmetry. No family history of breast cancer. LEFT DIAGNOSTIC MAMMOGRAM: An ML view 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, unchanged in pattern and distribution. There is redemonstration of a 0.8 cm oval mass at the 6 o'clock position of the left breast, which persists on spot compression imaging.LEFT BREAST ULTRASOUND: A targeted left ultrasound is performed for the mammographic area of concern. The 6 o'clock position of the left breast, 4 cm from the nipple, there is question of a partially circumscribed hypoechoic lesion measuring 0.7 x 0.7 cm. This lesion is subtle and does not demonstrate increased vascularity.
Persistent 0.8 cm mass at the 6 o'clock position of the left breast, with questionable sonographic correlate. Given visualization of this area is best seen on mammogram, a stereotactic guided biopsy of this lesion is recommended. Results and recommendation were discussed with the patient, who expressed understanding. The patient's daughter was present to facilitate translation.BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: H - Percutaneous Biopsy/Aspiration.
