Case contributed by Garth Kruger
Diagnosis almost certain


Previous left breast surgery for breast cancer. Palpable mass lesion on clinical exam.

Patient Data

Gender: Female

The serpiginous peripheral calcification around the lucent necrotic fat is typical of breast fat necrosis.

Case Discussion

The potential for confusion with malignant breast calcification arises when there is a small focus of fat necrosis with a small portion calcified. The key to picking this up is the history of a surgical intervention or breast trauma with a high index of suspicion. 

This is a typical appearance on mammography.
