Aims and objectives: Osteoblastoma (OBL) is a rare benign bone tumor, accounting for only 1% of all primary bone tumors (1, 2). It is more common in male (2:1 male to female ratio) in the 2nd or 3rd decades of life (3), four times less frequent than Osteoid Osteoma (OO) and most commonly involves the spine and the sacru[...]

Methods and materials: In the period between April 2010 to March 2015 we treated, under CT-guide, 13 patients (mean age 27 years) with imaging diagnosis of vertebral osteoblastoma. Lesion was reached through a 17G needle electrode put inside a 11G bone biopsy needle used as guide (Fig1.). We used a temperature control ra[...]

Results: The biopsy confirmed the diagnosis in 8/13 patients (in 5 patients the biopsy materials were considered insufficient). A regression in painful symptomatology was observed, in all patients, immediately after procedures (mean 4 days). 2 years after the treatment, the mean VAS value, improved overall b[...]

Conclusion: Our preliminary study demonstrates the safety and effectiveness of CT-RFA in the treatment of osteoblastoma, in terms of pain relief, reduction in pharmacological pain therapy and improvement in quality of life. Obviously more patients and a longer follow-up needed to confirm this encouraging resul[...]
