BI-RADS:

BI-RADS Category: 2 (benign)

Case summary:

Postmenopausal woman with increased risk of developing breast cancer presented for mammography screening. Diagnosed as typically benign calcifications in diffuse distribution in both breasts, BI-RADS 2 on imaging.

Learning points:


  • Mammography screening in high-risk women is recommended to start at an earlier age than in women with average risk. Some postmenopausal woman may have extremely dense breasts because of the unopposed estrogen influence, which lowers the sensitivity of mammography. They undergo supplementary breast ultrasound to look for small masses that may be obscured by the extremely dense breast parenchyma.
