27-year-old female with history of bilateral fibroadenoma and fibrocystic changes, predominantly on the right side, as well of bilateral breast discharge. Patient also has history of benign core biopsies at the left 11:00, right 10:00 and right 3:30 locations on 3/23/2016. Patient also has family history of breast cancer in mother. On recent bilateral breast MRI dated 5/4/2016, and multiple bilateral benign-appearing masses were identified and short-term follow-up recommended to ensure stability findings. There is heterogeneous fibroglandular tissue bilaterally, associated with marked background parenchymal enhancement slightly limiting the sensitivity and specificity of this study.RIGHT BREAST:Within the right upper outer quadrant, 10:00 position, posterior depth, an oval circumscribed homogenously enhancing 1.3 x 0.9 x 1.3 cm mass with focal central susceptibility artifact is reidentified, compatible with biopsy-proven fibroadenoma, stable in appearance. Multiple smaller similar benign-appearing masses are reidentified within the right breast.Focal susceptibility artifact from biopsy clip marker is reidentified within the right upper inner anterior breast, 3:30 position, at site of prior benign biopsy. Ectatic retroareolar ducts containing intrinsic high T1 signal proteinaceous material, stable in appearance. Associated periductal enhancement cannot appear likely assessed on this study due to presence of marked background parenchymal enhancement. There is no suspicious mass, morphology or enhancement in the right breast.LEFT BREAST:Within the left inner breast, an oval circumscribed enhancing 0.8 cm mass is reidentified with focal susceptibility artifact from biopsy clip marker along its posterior aspect, compatible with biopsy-proven fibroadenoma, stable in appearance. Multiple smaller similar benign-appearing masses are reidentified within the left breast.Ectatic retroareolar ducts containing intrinsic high T1 signal proteinaceous material, stable in appearance. Associated periductal enhancement cannot appear likely assessed on this study due to presence of marked background parenchymal enhancement. There is no suspicious mass, morphology or enhancement in the left breast.No abnormal lymph nodes are identified in either axillary or internal mammary region.
Multiple bilateral similar benign-appearing masses are stable in appearance dating back to MRI study of 5/4/2016. Follow-up MRI in one year is recommended.BIRADS: 2 - Benign finding.RECOMMENDATION: T - Take Appropriate Action - No Letter.
