A breast lipoma is a benign breast lesion and is classified as a BIRADS II lesion.
Lipomas are mostly asymptomatic and coincidentally discovered on routine mammography. Patients may present with a painless palable breast lump which is soft and mobile. In these cases the diagnosis is clinically obvious.
Skin tethering or fixation are not features of lipomas.
Typically seen as a radiolucent mass with no calcification (in rare situation there may be areas of fat necrosis presenting as calcification). Mammographic detection may be easier in a dense breast. In the vast majority of cases the lipoma is incidentally seen on routine screening.,
May be seen as a rounded lesion that is iso-echoic or at times slightly hyperechoic to surrounding fat. Occasionally a lipoma can also be hypoechoic 4. The lipoma can be readily distinguished from a hamartoma by the ultrasound and mammogram appearances.
These lesions are also found in males.
These lesions are rarely a diagnostic or imaging dilemma. Enlargement of a lipoma is an indication for biopsy.
