title: Simple bone cyst: investigation on the presence of gas in the cavity using computed tomography--review of 52 cases.
abstract: OBJECTIVE
  The purpose of this study was to evaluate whether gas is present in the cavities of simple bone cysts.
  
  
  METHODS
  Computed tomographic images of 52 simple bone cyst cases were reviewed and compared with the findings at surgery.
  
  
  RESULTS
  Whereas gas was confirmed at the time of surgery in 28 cases, no computed tomographic images indicated the presence of gas in the cavity. Bone expansion was noted in 13 of these 28 cases.
  
  
  CONCLUSIONS
  From these findings, we concluded that the presence of gas in the simple bone cyst cavity at surgery has been erroneously interpreted.
