title: Ultrasonographic features of spontaneous breast tumor infarction.
abstract: BACKGROUND
  The aim of this paper is to evaluate the ultrasonographic features of spontaneous breast tumor infarction.
  
  
  METHODS
  The pathologic information system database of the Department of Radiology was retrospectively searched. Between 2009 and 2011, nine cases in eight patients were pathologically confirmed as spontaneous breast tumor infarctions. Mammographic images and the ultrasonographic images were acquired. Two other radiologists analyzed the mammographic and ultrasonographic findings.
  
  
  RESULTS
  Most common features were oval, indistinct, heterogeneously hypoechoic mass with posterior enhancement. All lesions were classified as C4 (suspicious finding) except one case.
  
  
  CONCLUSIONS
  Spontaneous breast tumor infarction should be included in the differential diagnoses of hetereogeneously hypoechoic suspicious solid lesions mimicking malignancy.
