A search of the English-language medical literature found only two cases in which expansion of an osteochondroma into the lumbar spinal canal caused sciatica. We report another two cases of spinal nerve root compression by solitary lumbar spinal canal osteochondromas: in a 56-year-old man and a 55-year-old woman with no history of hereditary multiple exostoses. Osteochondromas compressing the spinal nerve root were seen at the inferior articular processes of the lumbar vertebrae by computed tomography (CT), three-dimensional reconstruction of CT scans, myelography, and magnetic resonance imaging. The symptoms disappeared after surgical removal of the lesions. Histopathologic examination confirmed the diagnosis of benign osteochondroma.
对英文医学文献的检索发现，仅有两例骨软骨瘤向腰椎管内扩展导致坐骨神经痛的病例。我们报告另外两例孤立性腰椎管骨软骨瘤压迫脊神经根的病例：一例为一名56岁男性，另一例为一名55岁女性，他们均无遗传性多发外生骨疣病史。通过计算机断层扫描（CT）、CT扫描三维重建、脊髓造影和磁共振成像，在腰椎的下关节突处发现了压迫脊神经根的骨软骨瘤。手术切除病变后症状消失。组织病理学检查确诊为良性骨软骨瘤。
