Fat containing breast lesions

Last revised by Dr Owen Kang on 04 Jun 2016

Fat containing breast lesions generally have some radiolucent component on mammography.


They are generally classified at BIRADS II lesions.

  • complex sclerosing lesion
    • looks like breast carcinoma, but often has a lucent center; usually 1-3 cm; at <1 cm these lesions have the same histology but are called radial scars and are not usually mammographically seen
