Right breast DCIS status post right lumpectomy of unclear extent on 1/22/2016 at outside hospital) assess posterior central calcifications, unclear from outside hospital imaging and up noticed posterior calcifications were excised. There is heterogeneous amount of fibroglandular tissue in both breasts, slightly asymmetric, more in the right breast than left.Moderate parenchymal enhancement is noted bilaterally, limiting the sensitivity of MRI.No definite seroma cavity or postsurgical changes identified in the right inferior breast. Minimal amount of fluid noted in the ductal system in the right breast 6:00 position.Focal area of nonmass enhancement measuring 14 x 7 x 14 mm (APx CC X ML) identified in the right central breast, anterior depth located approximately 12 mm from the nipple. Reviewing the location of the focal asymmetry that was biopsy proven DCIS on the mammogram, the area of non mass enhancement could be seen along the superior aspect of the lumpectomy site.No abnormal enhancement in the central posterior right breast at the site of prior small cluster of calcifications. Asymmetric parenchymal enhancement identified in the inferior right breast however this appears to be due to asymmetric distribution of glandular tissue (which is apparent on the T2 sequence and the mammograms) for which 6 month follow up MRI is recommended. No abnormal enhancement is seen in left breast. No abnormal lymph nodes are identified in either axillary region.
Focal nonmass enhancement in the right breast retroareolar region measuring 14mm. Given the lack of seroma, definite location of this focal non mass enhancement with respect to the lumpectomy site is difficult. However, this most likely is along the superior aspect of the biopsy proven cancer. Generous excision along the superior aspect of the lumpectomy bed can be performed. No abnormal enhancement in the central posterior right breast at the site of prior small cluster of calcifications. Limited examination due to moderate heterogenous parenchymal enhancement bilaterally, right inferior breast more than left for which 6 month follow up MRI is recommended. BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: T - Take Appropriate Action - No Letter.
