Ms. Morton is a 53-year-old female with a personal history of bilateral mastectomy for breast cancer (right - IDC, left - prophylactic) status post radiation and chemotherapy, followed by DIEP flap reconstruction on the right. She now presents with two palpable lesions in the right reconstructed breast. A targeted right ultrasound was performed for the palpable area of concern. In the right breast at the 2:00 position, approximately 3 cm from the nipple, is an oval, circumscribed, anechoic cyst measuring 10 x 6 x 12 mm, without internal vascularity, compatible with an oil cyst. In the right breast at the 8:00 position, approximately 6 cm from the nipple, is a mixed echogenic lesion measuring 6 x 6 mm, compatible with fat necrosis.
Benign oil cyst and fat necrosis in the right reconstructed breast, corresponding to the palpable areas of concern. No sonographic evidence for malignancy. The patient should follow up with her primary care physician as clinically warranted, presuming these results are concordant with the physical exam findings. All results and recommendations were discussed with the patient.BIRADS: 2 - Benign finding.RECOMMENDATION: C - Clinical Correlation Needed.
