Mastitis refers to inflammation of the breast parenchyma, of which there are a number of sub types:
- acute mastitis
- plasma cell mastitis (mammary duct ectasia): uncommon sub areolar inflammation without associated bacterial infection.
- granulomatous mastitis: rare; usually occurs due to tuberculosis or sarcoidosis
Clinically, the breast will be indurated, red and painful. Nipple retraction may also be evident. Nodal enlargement is common. The patient may often have systemic symptoms such as fever or leukocytosis.
On mammography, bacterial (puerperal or non-puerperal) mastitis will usually feature ill defined regions of increased density.
On ultrasound, ill-defined area of altered echotexture with hyperechogenicity representing infiltrated and inflamed fat lobules, hypoechoic areas in the glandular parenchyma, and associated mild skin thickening are seen. Inflammatory axillary lymph nodes may also be encountered. Occasionally abscess formation may be visible.
- breast abscess formation
It is important to consider inflammatory breast cancer as a potential differential.
