骨软骨瘤，也称为骨软骨外生骨疣，是最常见的良性软骨骨肿瘤之一，主要以孤立性病变形式发生。虽然通常出现在长骨中，但脊柱受累很少见，仅占该位置良性病变的一小部分。导致脊髓受压的孤立性骨软骨瘤很少见。我们描述了一名 34 岁男性的病例，没有明显的病史，出现提示脊髓受压的进行性症状。影像学研究显示，T8 椎体后弓左侧出现骨性病变，导致脊髓受压和脊髓病。需要进行手术干预来减压并获取组织学样本，从而使术后运动功能立即得到改善。病理检查得出骨软骨瘤的结论。骨软骨瘤主要影响骨骼生长，更常见的是孤立性病变，特别是在男性患者中。脊柱受累很少见，神经系统症状通常表明外生骨疣向管内延伸，导致神经元件受压。 MRI 等成像方式对于评估软骨厚度和脊髓受压影响至关重要。© 2024。作者，获得国际脊髓协会独家许可。

Osteochondromas, also known as osteocartilaginous exostosis, are among the most common benign cartilaginous bone tumors, primarily occurring as solitary lesions. While typically found in long bones, spinal involvement is rare, accounting for only a small percentage of benign lesions in this location. Solitary osteochondromas responsible for spinal cord compression are seldom.We describe the case of a 34-year-old male with no significant medical history, presenting with progressive symptoms suggestive of spinal cord compression. Imaging studies revealed a bony lesion originating from the left lateral aspect of the posterior arch of the T8 vertebra, causing spinal cord compression and myelopathy. Surgical intervention was necessary to decompress the spinal cord and obtain histological samples, resulting in immediate postoperative improvement in motor function. Pathologic exam concluded to an osteochondroma.Osteochondromas primarily affect growing bones and are more commonly observed as solitary lesions, particularly in male patients. Spinal involvement is rare, and neurological symptoms are typically indicative of intracanalar extension of the exostosis, leading to compression of neural elements. Imaging modalities such as MRI are crucial for assessing cartilage thickness and the impact of compression on the spinal cord.© 2024.
