title: Percutaneous radiofrequency coagulation of osteoid osteoma of the "Neural Spinal Ring".
abstract: METHODS
  Three cases of osteoid osteomas of the spine, adjacent to neural elements, were treated with CT-guided thermal coagulation.
  
  
  OBJECTIVE
  To present an alternative method to conventional treatment of spinal osteoid osteoma.
  
  
  BACKGROUND
  Percutaneous CT-guided radiofrequency coagulation has been successfully used for osteoid osteoma of the extremities. The conventional management of spinal osteoid osteoma is by surgical resection.
  
  
  METHODS
  Three patients with osteoid osteoma of the spine, adjacent to neural structures, were treated by percutaneous radiofrequency ablation. The procedure was performed in the CT room under general anesthesia and CT guidance. The thermocoagulation electrode was heated at 90 degrees C for 4 min.
  
  
  RESULTS
  Two patients left the hospital the same day; the third one was kept 24 h for observation. All of them had total pain relief within 48 h following the procedure. No complications were recorded. There was no evidence of recurrence after a mean follow-up period of 17 months.
  
  
  CONCLUSIONS
  Osteoid osteoma of the spine, adjacent to neural structures, can effectively and safely be treated by minimally invasive percutaneous CT guided radiofrequency coagulation.
