A 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. Plain X-ray revealed a large cauliflower shaped exophytic mass at the level of T8, T9 and T10 vertebrae. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an abnormal bony mass arising from the posterior arch of T9 with protrusion to the spinal canal and marked cord compression. The cortex and medulla of the lesion had continuity with those of the T9 vertebra. Surgical en bloc resection was performed and the patient's symptoms resolved. The histopathologic diagnosis was osteochondroma. In patients with symptoms of myelopathy, in addition to more common etiologies, one should also be aware of rare entities such as osteochondroma.
一名19岁男性，有5年背痛史，近一年来疼痛向下肢放射，伴有脚趾感觉异常。X线平片显示T8、T9和T10椎体水平有一个巨大的菜花状外生性肿块。计算机断层扫描（CT）和磁共振成像（MRI）显示T9后弓有一异常骨质肿块，突入椎管并明显压迫脊髓。病变的皮质和髓质与T9椎体的皮质和髓质相连。行手术整块切除，患者症状缓解。组织病理学诊断为骨软骨瘤。对于有脊髓病症状的患者，除了更常见的病因外，还应注意骨软骨瘤等罕见疾病。
