73-year-old female with history of left mastectomy in 2008 for IDC with extensive ductal carcinoma in situ. Patient is asymptomatic. No family history of breast cancer. Three standard views of the right breast were performed digitally, with additional right CC spot compression views, and reviewed with the aid of R2 CAD 9.3. The breast parenchyma is composed of scattered fibroglandular density(BiRads Density Category B), unchanged in pattern and distribution. Redemonstrated right retroareolar dilated ducts, stable in appearance dating back to at least 2013.Scattered round calcifications within the lateral right breast.Oval circumscribed isodense mass within the right lower inner quadrant at mid depth, appears slightly enlarged as compared with mammogram of 2015. Finding not well visualized on the RML view.No dominant mass, suspicious microcalcifications or areas of architectural distortion in the right breast. Benign appearing lymph nodes are projected over the right axilla.Targeted ultrasound of the right breast at the 4:00 position 3 cm from the nipple reveals an avascular circumscribed anechoic mass measuring 0.4 cm, compatible with a cyst. Targeted ultrasound of the right breast at the 2:00 position 3 cm from the nipple reveals an other 0.6 cm anechoic circumscribed avascular mass with posterior acoustic enhancement, also compatible with simple cyst. No other cystic or solid masses at the level of the finding on the CC view were seen, and one of these two cysts presumably represents the mammographic finding. Please note, multiple simple cysts were also present on previous breast MRI study of May 2008.
Two simple cysts within the right breast. No mammographic evidence of malignancy. As long as the patient's physical examination remains normal, right unilateral diagnostic mammogram is recommended annually. Results and recommendation were discussed with the patient.BIRADS: 2 - Benign finding.RECOMMENDATION: ND - Diagnostic Mammogram.
