Background
Osteoid osteoma is a benign osteoblastic tumor with a nidus of <20 mm in maximum diameter. There are several treatment options, all of them aiming either to resect or to eliminate the nidus.
Purpose
To report and to describe the benefits of treating non-spinal osteoid osteoma by percutaneous computed tomography-guided resection, according to our experience.
Study design
Retrospective case series
Methods
Between 1992 and 2008, 54 patients with non-spinal osteoid osteoma underwent primary treatment with percutaneous CT-guided resection. In all cases, the materials obtained were processed for pathology and microbiology.
Results
Fifty-four patients with a mean age of 22.7 years (range 10–47), of whom 46 were males (85.2 %) and 8 were females (14.8 %). The lesion size ranged between 5 and 15 mm with an average size of 6.9 mm. The resection was considered complete by the CT study in all 54 cases. Of all the specimens sent to pathology, the histological diagnosis was achieved in 41 (75.9 %). Cure was obtained in 50 patients (92.6 %) and the other four patients required a second surgery using the same technique, after which all of them achieved clinical and radiological improvement (100 %).
Conclusion
Percutaneous computed tomography-guided resection of non-spinal osteoid osteomas provides good results, similar to other surgical techniques, with the advantages of being a simple, mini invasive, safe and economic procedure without the need for specific materials. Level of evidence, IV.
