ORIGINAL ARTICLE PURPOSE We aimed to retrospectively evaluate the computed tomography (CT) and magnetic resonance imaging (MRI) findings of patients with osteoid osteoma treated with CT-guided radiofrequency ablation (RFA) along with the clinical outcome and long-term success. MATERIALS AND METHODSSeventy-three CT-guided RFA procedures were performed in 72 patients. The long-term success was assessed using a questionnaire including several visual analog scale scores. The CT evaluation included pre-and immediate postprocedural imaging of all 72 patients, and MRI was performed in 18 patients with follow-up imaging (mean, 3.4±2.2 months). The evaluation criteria included nidus morphology and a correlation with markers of clinical success. RESULTSThe primary technique effectiveness rate was 71/72 (99%). One relapse was successfully retreated, leading to a secondary technique effectiveness rate of 72/72 (100%). The longterm follow-up (mean, 51.2±31.2 months; range, 3-109 months) revealed a highly significant reduction of all assessed limitation scores (P < 0.001). The CT morphology was typical in all cases and did not change during the short-term follow-up. The follow-up MRI patterns varied considerably, including persistent nidus contrast enhancement in one-third (6/18) and persistent marrow edema in half (9/18) of the patients. None of the investigated MRI and CT patterns correlated with the clinical outcome. CONCLUSIONThe long-term outcome of CT-guided RFA of osteoid osteoma is excellent. There is no correlation of the CT and MRI patterns with the clinical outcome. Thus, the treatment decisions should not be solely based on the imaging findings. Investigators should also be aware of the variety of imaging patterns after RFA.

“…RFA is becoming one of the standard therapies for treating tumors of the kidneys and bone under appropriate indications. Other sites for which RFA has been used for tumor ablation that are considered to be experimental or investigational include the prostate, lungs, pancreas, osteoid osteomas, islet cells, breasts, endocrine organs such as the adrenal glands, head and neck organs, retroperitoneal organs, pelvic organs, subcutaneous or muscular tissues and so forth (24)(25)(26).…”

We herein present the case of a 41-year-old man who was misdiagnosed with a recurrent right shoulder tumor and underwent surgery twice. The pathological diagnosis was calcinosis. Secondary hyperparathyroidism was confirmed on further examination and the patient was therefore treated with two sessions of percutaneous ultrasonographically-guided radiofrequency tissue ablation. During the 20-month follow-up, the patient underwent four-hour hemodialysis three times a week. The calcinosis nearly completely resolved, and the PTH level was mildly elevated without the administration of any further medical therapy. Percutaneous ultrasonographically-guided radiofrequency tissue ablation is a feasible, safe and effective nonsurgical alternative treatment for secondary hyperparathyroidism.

“…The positioning of the cauterization needle in the nidus of the OO was performed with a guided CT approach with a series of continuous scans of 1 mm and two-dimensional reconstructions [1,15,16]. Two dispersive cauterizations were utilized and usually placed cranial to the lesion in order to reduce the spread of radiofrequency towards the mobile structures [2].…”

Osteoid osteoma of the cervical spine: surgical treatment or percutaneous radiofrequency coagulation?

et al. 2007

Osteoid osteoma (OO) of the cervical spine is frequently located close to the vertebral artery, spinal cord, or nerve roots and complete surgical excision is sometimes difficult by a limited approach and more extended surgery can require spinal fusion. Percutaneous radiofrequency coagulation (PRC) has demonstrated efficacy in the treatment of OO of the pelvis and limbs however, its role in the cervical spine is still nuclear. The Authors present a series of nine cases of OO of the cervical spine, six treated with surgical excision and three with PRC. No neurological or vascular complications occurred in both series. One case of the surgical series had only partial relief of persistent pain for 1 year due to incomplete excision, but is doing well 4 years after surgery. All the other surgical cases had complete relief of symptoms immediately after surgery and are symptom-free 3-10 years later. Two cases of PRC had complete relief of symptoms 24-48 h after surgery and are symptom-free 2 and 3 years later. One case of recurrent OO after surgery and treated with PRC with a reduced dose improved only, and still requires anti-inflammatory drugs 2 years after the procedure. Our still limited experience suggests that PRC can be safely performed in local anaesthesia with the patient awake, enabling to check for signs and symptoms of possible neurological injury. PRC can substitute extensive posterior approaches and reconstructions for OO of the posterior arch and joint pillar.
