Figure 2. Mediolateral oblique stereotactic mammograms obtained in a 64-year-old woman with a saline-filled subglandular implant (arrowheads), marked positioning problems, and suboptimally small tissue samples. A specimen radiograph (not shown) was negative. There is firm compression of the suboptimally displaced implant but poor compression of the adjacent breast tissue. A faint 7-mm cluster of amorphous calcifications (arrows) at the tip of the 14-gauge large-core needle and excellent prefire positioning are shown. The calcifications are better seen in both inset images. (Electronic magnification, x6.) Histopathologic slides (not shown) of the 12 suboptimally small tissue samples revealed fibrous tissue with no evident calcifications. Mammograms (not shown) have been stable for 70 months after biopsy. Cursor = orientation marker.
