Fat Necrosis

  • Fat necrosis of the breast:
    • Is a benign condition that most commonly occurs as the result of breast trauma or surgical intervention
  • Fat necrosis can be confused with a:
    • Malignancy on physical examination and may mimic malignancy on radiologic studies
  • It is sometimes necessary to biopsy these lesions to confirm the diagnosis:
    • Although experienced radiologists can usually determine that a lesion represents fat necrosis based on mammographic and ultrasound findings such as:
      • Oil cysts (collections of liquefied fat)
  • Once the diagnosis is established:
    • Excision is not necessary and there is no increased risk of subsequent breast cancer
