BIRADS category 5 lesion confirmed by postoperative histopathological findings as carcinoma mixtum (G2) in static elastography using breathing motion. In the B-mode (left) the lesion appears as hypoechoic with irregular, angular edges and irregular shape, with a hyperechoic rim around the lesion and with the dominance of lateral-lateral size over the anterior-posterior size. In the elastogram (on the right), the entire lesion is blue-coded (the blue encodes non-deformable tissues) – Tsukuba score 4.
