Ms. Robbins is a 27-year-old female who presents for initial screening MRI. Family history of breast cancer (mother 36, maternal aunt 50s, paternal grandmother 70s). No current breast complaints. There is extreme amount of fibroglandular tissue in both breasts. Moderate to marked background parenchymal enhancement is noted bilaterally, which limits the sensitivity of this examination.There are four oval circumscribed enhancing masses identified bilaterally (two - left breast, two - right breast). The largest of these masses is located in the left upper inner breast (approximately 10:00 position), measuring approximately 12 x 9 x 12 mm. The three additional circumscribed masses, located in the lower outer left breast (approximately 5:00 position), right retroareolar region, and lower inner right breast (approximately 6-7:00 position), have similar imaging features. MR findings are suggestive of bilateral benign fibroadenomas. No abnormal lymph nodes are identified in either axillary region.
High probability benign fibroadenomas in both breasts as described above. A short term 6 month follow-up MRI is recommended to document stability of these findings.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
