72-year-old woman recalled from screening mammography for architectural distortion in left breast (IMAGE)
Caption
A. Craniocaudal and B. mediolateral oblique digital breast tomosynthesis images demonstrate two areas of AD in upper outer left breast (circles) that persisted on additional diagnostic tomosynthesis images (not shown). C. Transverse greyscale ultrasound image of upper outer breast shows irregular hypoechoic mass with associated AD at 12:30 (arrow), corresponding to posterior AD. No ultrasound correlate was identified for anterior AD. Ultrasound-guided biopsy of posterior AD revealed malignancy (invasive lobular carcinoma). Tomosynthesis-guided biopsy of anterior AD yielded benign pathology (stromal fibrosis).
