40-year-old with strong family history of breast cancer and dense breasts. There is extreme amount of fibroglandular tissue in both breasts. Multiple high T2 signal cysts are present bilaterally. Moderate parenchymal enhancement is noted bilaterally. This includes numerous bilateral enhancing foci.In the right breast, there are a few scattered enhancing foci and small masses, several of which are similarly enhancing. This includes in the right infero- lateral retroareolar region and the right 9:00 position at mid depth.No abnormal enhancement is seen in the left breast. No abnormal lymph nodes are identified in either axillary region.Recommendations below resulted from consensus review of this study by 3 breast radiologists.
Right breast foci/small masses for which a 6 month follow up MRI is recommended to evaluate stability. The 6 month follow up study would best be performed at days 7-10 of her menstrual cycle to minimize the effects of her background breast parenchyma. BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
