Liponecrosis in breast refers to areas of mammary fat necrosis with associated dystrophic calcification. It is further divided into:
- liponecrosis microcystica calcificans: <3 mm
- liponecrosis macrocystica calcificans: >3 mm
Mammographic features are radiolucent round/oval lesions with small areas of dystrophic calcification which are often spherical and related to areas of previous breast trauma or surgery.
