The breast consists of milk-producing glands and ducts surrounded by fatty tissue. Lumps can form in this tissue when the breast is damaged or injured. Any procedure that disrupts the breast's fatty tissue can lead to breast fat necrosis, including:
Should I be worried about fat necrosis?
Although fat necrosis is benign, a doctor may recommend regular screening to ensure they have correctly identified a lump as fat necrosis, because it can be difficult to distinguish oil cysts from other types of lumps. Fat necrosis happens when inflammation affects the supply of blood and oxygen to body fat, causing fat cells to die.
Are other demographic factors associated with higher risk of fat necrosis?
Other demographic factors, such as race, are not associated with higher risk of fat necrosis. Fat necrosis is most common after breast surgery or radiation, so having breast cancer will raise your risk of fat necrosis. Breast reconstruction after cancer surgery may also increase your risk of fat necrosis.

Some people are offered a vacuum assisted excision biopsy to remove the fat necrosis. After an injection of local anaesthetic, a small cut is made in the skin. A hollow probe connected to a vacuum device is placed through this. Using ultrasound or mammography as a guide, breast tissue is sucked through the probe by the vacuum into a collecting chamber. The biopsy device is used until the fat necrosis has been removed. This may mean that an operation under a general anaesthetic can be avoided.

It may be triggered by chemicals, cold, trauma, radiation or chronic conditions that impair blood flow. 1 There are many types of necrosis, as it can affect many areas of the body, including bone, skin, organs and other tissues. It isn't always a clot or cold ...

What is the necrosis of fat?
Early in its development, fat necrosis appears as an area of hemorrhage in fat, resulting in induration and firmness on gross pathology. Over several weeks, the affected area becomes demarcated, forming a distinct yellow–gray and focally reddish mass. Cystic degeneration may occur, resulting in a cavity that contains oily fluid secondary to the necrotic fat. Calcifications frequently develop in the cyst walls [ 2 ]. On cytology, the early stage of fat necrosis is characterized by degenerative changes in adipocytes accompanied by hemorrhage (Figs. 1A and 1B ). In the intermediate stage of fat necrosis, there is infiltration of histiocytes and multinucleated giant cells ( Fig. 1C ). The degenerated RBCs conglomerate in the setting of high levels of free fat released by the necrotic adipocytes. These conglomerations are referred to as “myospherulosis,” which is characteristic of fat necrosis on cytology ( Fig. 1D ). In the late stage of fat necrosis, usually hemosiderin deposition and the development of fibrosis (Figs. 1E, 1F, and 1G) are seen. Reactive inflammatory components replaced by fibrosis lead to scar formation. Loculated degenerated fat or oil may persist for months or years in a cyst surrounded by fibrosis [ 1 ]. Sometimes, fibrosis and calcifications are the only sequelae of fat necrosis ( Fig. 1H ). The varied appearances of fat necrosis on imaging studies are attributed to various amounts of histiocytic infiltration, hemorrhage, fibrosis, and calcification.
What are the features of fat necrosis?
The sonographic features of fat necrosis are varied and reflect the degree of fibrosis. Fat necrosis may present as a solid mass ( Fig. 9 ), a complex mass with mural nodules, a complex mass with echogenic bands, an anechoic mass with posterior acoustic enhancement, an anechoic mass with shadowing [ 5, 6 ], or an isoechoic mass [ 7 ]. The margins range from well circumscribed ( Fig. 10) to indistinct ( Fig. 11) to spiculated (Figs. 12A and 12B ). Bilgen et al. [ 8 ], in a retrospective study of 126 cases of fat necrosis, found a wide distribution of sonographic presentations, including increased echogenicity of the subcutaneous tissues, with or without small cysts (in 26.9% of cases); anechoic masses with posterior acoustic enhancement (in 16.6% of cases); anechoic masses with posterior acoustic shadowing (in 15.8% of cases); solid-appearing masses (in 14.2% of cases); cystic masses with internal echoes (in 11.1% of cases); and cystic masses with mural nodules (in 3.9% of cases). A mass with echogenic internal bands that shift in orientation with changes in patient position has been described as a specific sonographic indicator of fat necrosis. It is thought that these bands represent the interface between the lipid and the serous–hemorrhagic components of fat necrosis [ 6 ].
Why does fat necrosis appear on MRI?
On MRI, the appearance of fat necrosis is due to the amount of the inflammatory reaction, the amount of liquefied fat, and the degree of fibrosis. Fat necrosis may show enhancement after the administration of IV paramagnetic contrast material.

In this article, we review the clinical and the histopathologic features of fat necrosis and the different appearances on mammography, sonography, and MRI; and we correlate the imaging, histopathologic, and the cytologic findings. After reviewing this article, the reader should be familiar with the varied presentations of fat necrosis on imaging studies.
