title: Nontraumatic avulsions of the pelvis.
abstract: OBJECTIVE
  The purpose of this report is to describe the imaging findings of nontraumatic avulsions of the pelvis.
  
  
  CONCLUSIONS
  A diagnosis of avulsion fracture of the pelvis in an adult without appropriate history of substantial trauma must raise the suspicion of an underlying malignancy. If a patient has not been diagnosed as having a primary neoplasm, additional imaging evaluation is recommended. Also, biopsy may be considered in the proper clinical setting.
