OBJECTIVE: To report the results of computed tomography (CT)-guided percutaneous
resection of the nidus in 18 cases of osteoid osteoma. MATERIALS AND METHODS: The
medical records of 18 cases of osteoid osteoma in children, adolescents and young
adults, who underwent CT-guided removal of the nidus between November, 2004 and
March, 2009 were reviewed retrospectively for demographic data, lesion site,
clinical outcome and complications after procedure. RESULTS: Clinical follow-up
was available for all cases at a median of 29 months (range 6-60 months). No
persistence of pre-procedural pain was noted on 17 patients. Only one patient
experienced recurrence of symptoms 12 months after percutaneous resection, and
was successfully retreated by the same technique, resulting in a secondary
success rate of 18/18 (100%). CONCLUSION: CT-guided removal or destruction of the
nidus is a safe and effective alternative to surgical resection of the osteoid
osteoma nidus.
