Fat necrosis left breast

Case contributed by Dr Garth Kruger

Presentation

Mammogram images of the left breast in a patient who was treated for carcinoma.

Patient Data

Age: Adult
Gender: Female
Mammography

Post therapy changes to the left breast with surgical scarring visible with a typical parenchymal distortion related to the surgical scar.

Note the subtle lucencies in the subareolar breast tissue. They are the early changes of fat necrosis.

Mammography

The typical serpiginous circumferential calcification of fat necrosis. Two years after the images above and almost 4 years after the surgery.

Note how the skin changes from radiation around the nipple have almost disappeared two years later.

Ultrasound

The lesions are the lesions shown on the mammogram images. The thin rim of calcification is visible and the necrotic fat is slightly echogenic. This is not a tumour and no work up is indicated.

Case Discussion

Another case to bring home the point that fat necrosis in the breast can and does change with time. Do not let the early peripheral  calcifications confuse you with possible DCIS.  The lucencies are invariably seen on previous mammograms if they are available and good quality.
