Ms. Smoke is a 35 year old female with a personal history of left breast lumpectomy in 03/2015 for IDC treated with radiation, chemotherapy and hormonal therapy. There is heterogeneous amount of fibroglandular tissue in both breasts. Mild parenchymal enhancement is noted bilaterally.There is diffusely increased parenchymal enhancement seen throughout the left breast, which is asymmetric when compared to the contralateral breast. However, there is no discrete enhancing focus/mass within the left breast which is more suspicious than the rest. Expected postsurgical distortion is seen in the left superior breast, compatible with history of recent lumpectomy.There is no abnormal enhancement seen in the right breast. No abnormal lymph nodes are identified in either axillary or internal mammary region.
(1) Diffusely increased parenchymal enhancement in left breast, likely related to post-therapy changes. However, a short-term follow-up MRI is recommended in order to confirm stability/resolution of these findings. One year follow-up time period is adequate, assuming patient is to get annual surveillance MRI examinations. (2) No MRI evidence for malignancy in the right breast. BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
