Fig. 4From: The added value of digital breast tomosynthesis in improving diagnostic performance of BI-RADS categorization of mammographically indeterminate breast lesionsA 48-year-old woman complains of a left breast lump. a Craniocaudal and (b) mediolateral oblique DM images of left breast reveal heterogeneous dense breast (BI-RADS C) with upper outer quadrant dense lesion with obscured margin (arrows). No spiculated masses or microcalcifications. c Craniocaudal and (d) mediolateral oblique DBT images show a well-defined rounded medium dense lesion with smooth margins and minute peripheral calcific foci, measures 16 × 16 mm and associated with the characteristic halo sign (arrows). The lesion was categorized as BI-RADS 4c by DM and BI-RADS 2 by DBT. Histopathology after US-guided biopsy revealed simple cystBack to article page
