Figure 1a. Mammograms in a 38-year-old woman with a lump at the 4-oclock position in the right breast. (a) Craniocaudal and (b) mediolateral oblique mammograms of both breasts. The glandular tissue was considered to be of high density, without a focal abnormality in the area of clinical concern. The pathologic diagnosis was high-grade DCIS.

Figure 2a. Mammograms and a sonogram in a 57-year-old woman with a lump at the 5-oclock position in the left breast. (a) Craniocaudal and (b) mediolateral oblique mammograms of both breasts. The glandular tissue was considered to be of high density. A subtle mass may have been present on the initial mammogram, best seen on the mediolateral oblique projection. (c) Initial mediolateral oblique mammogram (left) and mediolateral oblique mammogram obtained 4 months later (right). An ill-defined mass (arrow) is seen in the inferior left breast. (d) Transverse sonogram in the lateral lower quadrant demonstrates an ill-defined hypoechoic 4.5-cm mass. The arrows delineate two lobulations within the mass. The crosshairs depict the anteroposterior dimension (2.9 cm) of the mass. The histopathologic diagnosis was stage T3 invasive lobular carcinoma.
