56-year-old female recalled for asymmetry in the lateral aspect of the right breast seen on screening mammogram One standard ML mammographic view of the right breast was performed followed by 2 right CC spot compression views and medial and lateral rolled CC views. Targeted grayscale and color Doppler ultrasound was subsequently performed and a BB was placed on the skin. Mammograms were then obtained with tangential and LMO views.The breast parenchyma is composed of scattered fibroglandular density, unchanged in pattern and distribution. The asymmetry in the lateral breast that triggered this exam was not evident on spot compression views. Medial rolled CC views demonstrated lateral displacement of the 5 mm asymmetry, which has the appearance of a circumscribed cyst as subsequently demonstrated by ultrasound.Targeted ultrasound of the right lower quadrant showed an anechoic, unilocular cyst with no internal flow measuring 3 x 3 x 3 mm located 8 cm from the nipple along the 8:00 radian. A BB was placed on the cyst. Tangential and LMO views of the right breast confirm that the cyst corresponds to the asymmetry that triggered this exam.
Asymmetry identified on the screening mammogram corresponds to a simple benign cyst. No further evaluation is necessary. No mammographic evidence of malignancy. As long as the patient's physical examination remains normal, annual bilateral screening mammography is recommended. The results and recommendations were discussed with the patient at the completion of the exam.BIRADS: 2 - Benign finding.RECOMMENDATION: NS - Screening Mammogram.
