A patient with known left breast cancer submitted outside study for review. Submitted for review are breast MRI (3/18/15) performed at Northwestern Memorial Hospital. Breast MRI was performed with a protocol outlined in the outside radiology report.There is marked parenchymal enhancement in both breasts, significantly limiting the sensitivity and specificity of this study.There are innumerable cysts in both breasts. A proven malignancy is demonstrated as an enhancing mass at far posterior 3 o'clock position, measuring 29 x 20 x 32 mm (AP x LR x CC), in the left breast. There is a linear non-mass enhancement at anterior 10 o'clock position in the left breast, measuring 17 x 8 x 10 mm.In the right breast, there is an enhancing mass, measuring 8 x 8 x 10 mm, at far posterior 10 o'clock position.Axillary regions are not completely imaged in this study.
Limited MRI study due to marked parenchymal enhancement.1. Known cancer in the left breast at far posterior 3 o'clock position.2. Linear non-mass enhancement at anterior 10 o'clock position in the left breast. MR guided biopsy may be considered.3. An enhancing mass in the right breast at posterior 10 o'clock position. MR directed ultrasound study is recommended. If no sonographic correlate is obtained, MR guided biopsy may be considered.BIRADS: 4 - Suspicious Abnormality.RECOMMENDATION: T - Take Appropriate Action - No Letter.
