Osteoid osteoma is a small, benign but painful lesion with specific clinical and imaging characteristics. Computed tomography is the imaging modality of choice for visualization of the nidus and for treatment planning. Complete surgical excision of the nidus is curative, providing symptomatic relief, and is the traditionally preferred treatment. However, surgery has disadvantages, including the difficulty of locating the lesion intraoperatively, the need for prolonged hospitalization, and the possibility of postoperative complications ranging from an unsatisfactory cosmetic result to a fracture. Percutaneous radiofrequency (RF) ablation, which involves the use of thermal coagulation to induce necrosis in the lesion, is a minimally invasive alternative to surgical treatment of osteoid osteoma. With reported success rates approaching 90%, RF ablation should be considered among the primary options available for treating this condition.
骨样骨瘤是一种良性但疼痛的小病灶，具有特定的临床和影像学特征。计算机断层扫描是显示病灶和治疗计划的首选影像学方法。完全切除病灶是治愈性的，可以缓解症状，是传统上首选的治疗方法。然而，手术有其缺点，包括术中定位病灶的困难、需要长时间住院以及术后并发症的可能性，从不满意的美容效果到骨折都有可能发生。经皮射频（RF）消融术涉及使用热凝固来诱导病灶坏死，是一种微创替代手术治疗骨样骨瘤的方法。据报道，其成功率接近 90%，RF 消融术应被视为治疗这种疾病的主要选择之一。
