Bilateral skin/nipple sparing mastectomy in 2009 for right breast ADH/ALH. Status post immediate reconstruction with implants. Left breast thickness/density at 12:00 position, please assess on MRI Status post bilateral mastectomy with bilateral subpectoral silicone/gel implants which appear intact. No evidence of intra or extracapsular rupture.Bandlike area of enhancement is identified between the implant and the skin in the right chest wall at 5 to 6:00 position (close to the inframammary fold), that is dark on T2-weighted sequence measuring 2.5 x 1.1 x 0.5 cm (APX ML x CC ).Similar morphology band like area of enhancement is also identified between the implant and skin surface measuring 1.3 x 0.7 x 0.6 cm (APX ML x CC ) at the 12:00 to 1:00 position of the right chest wall. These areas of enhancement appear to be related to Alloderm configuration used at the time of reconstruction surgery. No abnormal enhancement is seen in either chest wall. No abnormal lymph nodes are identified in either axillary region.
No MRI evidence for malignancy especially in patient's area of concern (area of thickness/density in left breast at 12:00 position). Band like areas of enhancement along the inframammary fold and 12 to 1:00 position of the right chest wall are most likely related to alloderm usage at the time of reconstructive surgery or fat necrosis. BIRADS: 2 - Benign finding.RECOMMENDATION: X - No Letter.
