Malignant focal asymmetry in a 49 years old female complaining from palpable right breast lesion (A) CC and (B) MLO mammography views of both breasts revealed right breast LIQ para-areolar area of focal asymmetry (arrows). (C) CC and (D) MLO 3D digital tomosynthesis was done and showed associated subtle architectural distortion, no suspicious microcalcification assigned as BIRADS 4a (arrows), the well circumscribed oval shape dense mass lesion (dashed arrows) at LOQ represents fibroadenoma (BIRADS 3). (E) Ultrasound revealed ill-defined area of pathological altered heterogeneous parenchyma, no associated suspicious LNs given BIRADS 4a. The focal asymmetry here proved ductal carcinoma in situ by histopathological correlation
