Diagnostic transverse ultrasound image of the left breast in a 64-year-old woman shows irregular hypoechoic nonparallel mass with indistinct margins corresponding to palpable finding, assessed as BI-RADS category 4. Both readers assessed mass as having associated echogenic rind with complete circumferential extent (arrowheads). Ultrasound-guided biopsy of mass yielded diagnosis of invasive ductal carcinoma (intermediate grade, luminal A molecular subtype, no lymphovascular invasion).
