Benign patterns of calcifications

Benign patterns of calcifications (arrows) in 3 patients. Vascular calcifications are seen in the lateral aspect of the breast on a CC mammogram (Panel A). Multiple coarse "popcorn" calcifications are characteristic features of calcifying fibroadenomas (Panel B). Bilateral, benign, large, rod-like secretory calcifications are seen in CC views of both breasts (Panels C and D). The rod shape is better seen on the magnification view (Panel E).
