Imaging-guided radiofrequency ablation of osteoid osteoma in typical and atypical sites: Long term follow up


Francesco Somma, Vincenzo Stoia, Roberto D’Angelo, Francesco Fiore:To assess efficacy and safety of imaging-guided radiofrequency ablation (RFA) of Osteoid Osteoma (OO) in both typical and atypical sites.

Osteoid osteoma (OO) is a benign bone tumor (10% of benign bone tumors), composed of a central nidus generally of less than 15 mm in diameter and surrounded by osteoblasts and peripheral reactive zone of thickened cortical or trabecular bone and loose fibro vascular tissue . It is more frequent in males, usually in young adults .

Herein, we present our oncologic center experience to assess efficacy and safety of CT guided RFA in the treatment of OO located both in typical and atypical sites, trying to answer the question whether or not OO in typical and atypical sites have different prognosis.
