title: Chondrosarcoma and myositis ossificans.
abstract: OBJECTIVE
  To discuss the clinical radiographic findings in a 70-yr-old woman suffering from chondrosarcoma.
  
  
  METHODS
  The patient experienced right SI pain present initially only at night. She later developed morning numbness. An X-ray examination revealed a flocculent calcification in the right buttock region. Computed tomographic scans confirmed the diagnosis.
  
  
  RESULTS
  Initial palliative care continued until surgery was performed to resect the area.
  
  
  CONCLUSIONS
  Chondrosarcoma is a severe disease that must be differentiated from myositis ossificans.
