Key words: Osteoid osteoma, Treatment, Percutaneous radiofrequency ablation
Osteoid osteoma (OO) is a small, benign bone tumour that occurs in young people. The most common skeletal sites are the metaphysis or diaphysis of long bones. We report a case of a 13-year-old boy with a 5-month history of pain in the right femur. For the persistence and the increasing of the pain the boy underwent a right lower limb CTscan that revealed a well-defined, 5 mm cortical lesion of the distal femur characteristic of an OO. Therefore a percutaneous radiofrequency ablation (PRA) of the OO under CTscan guide was performed: after the treatment there was a complete remission of the pain and at the 3-month-follow-up the child remained symptoms free. Our experience confirms literature data supporting the use of PRA as a minimal invasive and effective treatment for OO.
