title: Osteoid osteoma: CT-guided percutaneous resection and follow-up in 38 patients.
abstract: OBJECTIVE
  To reevaluate at medium term the results of computed tomography (CT)-guided percutaneous resection of osteoid osteomas.
  
  
  METHODS
  Thirty-eight patients who had undergone treatment by means of this technique were reexamined with a mean follow-up of 3.7 years. The short- and medium-term clinical course and histologic features of the resection specimens were analyzed.
  
  
  RESULTS
  The bone fragment could be analyzed in all cases, and the diagnosis of osteoid osteoma was confirmed in 28 patients (74%). A different diagnosis was made in six patients: mucoid cyst, subchondral arthritic geode, fibrous dysplastic lesion, focal osteochondritis, or focal chronic osteomyelitis. Cure was obtained in 32 patients (84%), whatever the cause. Complications, generally minor and transient, were observed in nine patients (24%). The most severe complications were two femoral fractures and one focal chronic osteomyelitis due to Staphylococcus aureus infection.
  
  
  CONCLUSIONS
  The results of this study confirm the efficacy of percutaneous resection of osteoid osteomas and the possibility of using this method for successful treatment of other small bone lesions.
