Figure 7c. Correlation of mammographic and US findings. Mammography performed at another hospital revealed fine, pleomorphic, clustered microcalcifications in the left breast. (a) US image reveals a cluster of tiny hyperechoic foci (arrowheads) in the left subareolar area. A BB marker was positioned on the skin overlying this cluster. (b) Left-sided coned compression magnification view shows a suspicious cluster of microcalcifications in the area of the BB marker. (c) Specimen mammogram obtained after US-guided biopsy shows the targeted microcalcifications (arrows), which were diagnosed as ductal carcinoma in situ.
