Images in (A–D) a 48-year-old female patient and (E–H) a 65-year-old female patient. (A) Left mediolateral oblique (LMLO) prevalent digital breast tomosynthesis (DBT) screening image shows an irregular mass (circle). (B) Prior screening digital mammogram (DM) suggests the mass may have been present but was not depicted. (C) DBT section image shows spiculated margins (circle). (D) US image shows a corresponding irregular hypoechoic mass. A 2.4-cm estrogen receptor– and progesterone receptor–positive, human epidermal growth factor receptor–negative invasive ductal carcinoma was found at pathologic evaluation. (E) Incident DBT screening image shows a new mass in the right breast (circle). (F) Previous DBT scan shows no finding. (G) DBT section image shows spiculated margins (circle). (H) US image shows a small irregular hypoechoic mass. A 0.6-cm estrogen receptor– and progesterone receptor–positive, human epidermal growth factor receptor–negative invasive ductal carcinoma was found at pathologic evaluation. RCC = right craniocaudal.
