Figure 2d. Images in a 42-year-old woman with a mass with calcifications that was discovered at screening mammography. (a) US image obtained before VAB in the radial plane shows a markedly hypoechoic mass (arrow) of 0.6 cm in mean diameter with angular margins. (b) US image obtained immediately after VAB with the device still inserted shows the biopsy probe (arrows) and no residual mass. (c) Radiograph of the specimens taken from the mass shows calcifications (arrows). The histologic diagnosis was DCIS (intermediate and high grades, solid and cribriform types). (d) Radiograph of five biopsy samples taken from the cavity margins does not reveal calcifications, and no carcinoma was found at histologic examination of these specimens. The excised surgical specimen contained residual DCIS extending up to 0.5 cm from the edge of the VAB cavity.
