Chronic or later (months to years) postsurgical ultrasonographic findings are usually related to scar formation (ie, retraction, dystrophic calcifications, and fat necrosis [lipophagic granuloma, oil cyst]). Scar formation can be seen as a discrete area of architectural distortion with hypoechoic structures, acoustic shadowing, and interruption of the normal parenchyma. Frequently, these findings originate at the scar and extend into the breast parenchyma. This appearance can mimic that of cancer.
