57-year-old female with history of left breast mass status post trauma. Annual follow-up. Family history of breast cancer in maternal cousin. Mammogram: Three standard views of both breasts were performed digitally and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is almost entirely fatty, unchanged in pattern and distribution. An 10:00 position of the left breast, the previously mentioned dense mass has significantly decreased in size now measuring 20 x 8 mm. There are stable subcentimeter benign type masses, likely benign intramammary lymph nodes, in the left upper outer quadrant.The right breast is unremarkable.Ultrasound: A targeted left breast ultrasound was performed in the area of mammographic abnormality at the 10:00 position. Approximately 8- 10 cm from the nipple at the 10:00 position, there is a mixed echogenicity oval lesion with a hyperechoic rim which has significantly decreased in size now measuring 16 x 7 x 5 mm (compared to 13 x 12 x 12 mm on prior). There was no internal vascularity.
Findings compatible with a resolving hematoma in the left breast. 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.
