A patient submitted outside study for review. Submitted for review are MRI guided biopsy images and right breast mammogram dated 5/13/2015 and performed at Rush University Medical Center. For comparison, MRI breast 4/21/2015 are available. MRI breast 4/21/2015: There is extreme amount of fibroglandular tissue in both breasts. Mild parenchymal enhancement is noted bilaterally. There is a 8 x 5 x 5 mm irregular mass in the right breast at the 11 to 12 o'clock position, for which MRI guided biopsy was subsequently done. Multiple cysts are seen in both breasts, right greater than left, on the T2W sequences.MRI breast guided biopsy and right breast post-procedure mammogram 5/13/2015: The obturator of the biopsy needle is along the posterior aspect and slightly deep to the 8 mm irregular mass at the time of biopsy in the right breast. Post-procedure ML and exaggerated CC lateral view of the right breast showed the biopsy clip to be in the appropriate location in the upper outer to central breast. Multiple scattered calcifications are present.Outside hospital pathology results from this biopsy showed Grade I DCIS, which is felt to be concordant with imaging.
8 mm irregular enhancing mass in the right breast 11 to 12 o'clock position biopsied to be Grade 1 DCIS with an appropriately positioned biopsy clip.Kindly submit bilateral diagnostic mammogram if performed. BIRADS: 6 - Known cancer.RECOMMENDATION: T - Take Appropriate Action - No Letter. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
