CT guided radiofrequency ablation for an osteoid osteoma in the pediatric proximal humerus

Abstract

Background: Osteoid osteoma is a benign tumor commonly seen in the lower extremity. It presents between the ages of 10 and 30 years with male predominance. The most common symptom is bone pain, worsening at night and relieved by aspirin or nonsteroidal anti-inflammatory drugs. Osteoid osteoma in the pediatric proximal humerus is rare. Case description: We report a 14-year-old girl with an osteoid osteoma in the proximal humerus successfully treated by CT-guided RF ablation. Literature review: There is a considerable delay in the diagnosis because of common pathological conditions around the shoulder mimic osteoid osteoma. Computer Tomography is the best imaging modality to visualize the nidus and radiolucent lesion and assist in the treatment. Clinical relevance: CT-guided percutaneous radiofrequency ablation of proximal humerus osteoid osteoma in children is safe, effective, and a reliable method alternative to surgery with a low complication and recurrence rate.
