B. Incorrect. Ductal carcinoma in situ (DCIS) is usually detected on mammography with calcifications ...

A. Incorrect. The mammogram would be abnormal because silicone outside the fibrous capsule (that which is created by the body in reaction to the implant) can be seen mammographically as streaky densities, dense masses, and bright foci within lymph nodes. Mammography is sensitive enough to diagnose silicone implant rupture when the silicone is ...
Evaluating the density of a mass is important in providing a differential diagnosis. Density should be
compared to the surrounding breast parenchyma or, as in this case of a fatty replaced breast, to the nipple. The differential diagnosis for a mass containing both radiolucent and radiopaque components would include: Hematoma, galactocele, intramammary lymph node, and ...
