Fig. 5. —56-year-old woman with recurrent carcinoma manifesting as unusual microcalcifications (arrows) on spot magnification mammogram. At histopathology, calcifications were in necrotic center of infiltrating ductal carcinoma that developed at site of lumpectomy 8 years earlier for ductal carcinoma in situ. Four observers considered these calcifications to be coarse: three assessed them as benign (BI-RADS category 2) and one as probably benign (BI-RADS category 3). One observer described these as amorphous and benign (BI-RADS category 2).
