Archived Case 9

This mass has the classic appearance of fat necrosis by mammography, and an ultrasound is not necessary

All fat-containing masses are considered benign findings. Fat necrosis is a rapidly evolving process compared with most other findings in the breast. One would expect that this area will look different on next year’s screening mammogram.

This is a common occurrence following trauma, including surgical causes such as lumpectomy. These areas will often evolve into a fibrotic scar, often with associated coarse calcifications.
