title: [The significance of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts].
abstract: OBJECTIVE
  To investigate the significance and images characters of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts(FTB).
  
  
  METHODS
  From June 2005 to June 2012, 13 cases with 96 fat necrosis lumps after FTB, were retrospectively reviewed. The pre-operative images of ultrasound and mammography, as well as the post-operative histologic results were collected.
  
  
  RESULTS
  All the 96 lumps were histologically diagnosed as fat necrosis. They were lipo-necrotic cysts with thin wall(29 lumps), or thick wall(52 lumps), or no wall(15 lumps). The cysts with wall could be distinguished both in the images of ultrasound and mammography, but the cysts without wall could only be found in mammography images, not in ultrasound images.
  
  
  CONCLUSIONS
  Most fat necrosis lesions show a special cystic images with thin or thick wall in ultrasound and mammography. Irregular lesions without wall can be distinguished in the mammography images, but may be mis-diagnosed in the images of ultrasound. The images characters of fat necrosis lesions in mammography are not confused with the breast tumor.
