Figure 3.
The different stages of fat necrosis. These images are of a 46-year-old female who completed her left total breast reconstruction with AFT 1 year ago. She received a target US. (A) A hyperechogenic area, where a hyperacute phase within the subcutaneous tissue is seen. (B) The inflammatory phase where an oil cyst is starting to form. It also includes a small part of fibrosis in the anterior part of the cyst. This is the third pathophysiological phase. (C) An almost complete oil cyst that only has a small part of fibrosis in the anterior part of the cyst left. Abbreviation: AFT = autologous fat transfer.
