Figure 5: A 61-year-old woman with palpable mass in the right breast. (a) Digital mammograms showed focal increased density (arrowhead) without architectural distortion in the right breast. (b) Tomosynthesis clearly delineated the smooth border of a mass lesion (arrowhead) without showing malignant feature. This case was considered as true negative in both digital mammography and tomosynthesis. (c) Color ultrasound showed a cystic-like lesion (C) with hypervascular mural nodule (MN). The lesion was proved to be ductal carcinoma in situ, TisN0M0.
