A patient submitted outside study for review. Submitted for review are mammogram dated 5/12/2016 and breast MRI 7/13/2016 performed at Rush University Medical Center. For comparison,mammogram 5/11/2015 is available. Mammogram 5/12/2016:The breast parenchyma is heterogeneously dense, which may obscure small masses (BiRads Density Category C), unchanged in pattern and distribution. No suspicious masses, microcalcifications or areas of architectural distortion are present. MRI breast 7/13/2016:Uploaded on DYNACADHeterogenously dense breast density noted. Mild parenchymal enhancement noted in both breast. There is a 6 x 4 x 6 mm circumscribed benign morphology enhancing lesion with T2 correlate within the posterior depth at the 12:00 position within the right breast. This most likely represents a benign etiology such as complicated enhancing cyst or lymph node.No abnormal area of enhancement noted in both breasts or axillary regions.
Given the benign morphology lesion within the posterior depth at the 12:00 position of the right breast, MR directed ultrasound is recommended to confirm benign etiology. If lesion is occult by ultrasound, short term MR follow-up is recommended in 6 months.BIRADS: 0 - INCOMPLETE; Need additional imaging evaluationRECOMMENDATION: X - No Letter.
