We report a case of 14-year-old male patient with osteoid osteoma of the cervical spine. Magnetic resonance imaging (MRI) revealed a large dumbbell-shaped paravertebral tumor in the region of the exiting left C6 nerve. A computed tomographic (CT) scan after myelography showed a much smaller bony defect in the medial aspect of the left C6 pedicle with central calcification and extensive bone sclerosis around the defect, typical of osteoid osteoma. The diagnosis was confirmed postoperatively. The resected specimen exhibited extensive vascularization of the osteoid tissue. The case is presented because MRI did not allow a specific diagnosis of osteoid osteoma, and suggested the tumor was larger than in reality it was, by also depicting the reactive inflammation around the tumor as if it were part of the tumor.
我们报告一例14岁男性颈椎骨样骨瘤患者。磁共振成像（MRI）显示在左侧C6神经根穿出区域有一个巨大的哑铃形椎旁肿瘤。脊髓造影后的计算机断层扫描（CT）显示左侧C6椎弓根内侧有一个小得多的骨缺损，中央钙化，缺损周围有广泛的骨质硬化，这是骨样骨瘤的典型表现。术后确诊。切除的标本显示骨样组织有广泛的血管化。之所以呈现该病例，是因为MRI无法对骨样骨瘤做出明确诊断，且通过将肿瘤周围的反应性炎症描绘成肿瘤的一部分，提示肿瘤比实际更大。
