45 year-old asymptomatic female presents for routine screening mammography. Family history of breast cancer in 2 maternal aunts. Two standard digital views of both breasts were performed with tomosynthesis and reviewed with the aid of R2 CAD. The breast parenchyma is heterogeneously dense, which may obscure small masses (BiRads Density Category C), unchanged in pattern and distribution. Asymmetry in the right upper breast seen on the MLO view appears increased in size; this is questionably seen on the CC view. Round obscured mass in the right breast 12:00 position has decreased in size and was previously confirmed to be a cyst on ultrasound. Benign coarse calcifications in the left breast are stable. No suspicious masses or microcalcifications.
Asymmetry in the right upper breast on the MLO view for which further evaluation with spot compression views, and possibly ultrasound, is recommended.BIRADS: 0 - INCOMPLETE; Need additional imaging evaluationRECOMMENDATION: EC - Additional Mammo/Ultrasound Workup Required.
