Calcifications frequently appear on mammograms and need to be classified as benign or malignant. One benign pattern is that of secretory calcifications. These calcifications (red arrows above) are smooth, linear or rounded, and radiate towards the nipple (long axis pointed towards the nipple). A branching pattern may be seen. The calcifications may have a radiolucent center indicating the noncalcified ductal lumen. Secretory calcifications are often bilateral and symmetric in distribution.
The blue arrows show a region of smaller, clustered calcifications which were found to be malignant.
