摘　　要：目的探讨腰椎后缘软骨结节的CT诊断、分型和鉴别诊断,加深对腰椎后缘软骨结节的认识。方法对53例腰椎后缘软骨结节的临床和CT资料进行回顾性分析。结果腰椎后缘软骨结节的CT表现为椎体后缘松质骨内类圆形、不规则形骨质缺损区,大小不一,与椎间盘密度一致,周围有不同程度的硬化,缺损区后方骨块突入椎管内,全部或部分与椎体分离或不分离。根据软骨结节后壁是否完整可分为后缘软骨板完整型(28个,占44.44%)和后缘软骨板破裂型(35个,占55.56%)。结论 CT检查能明确诊断腰椎后缘软骨结节,并为制订治疗方案提供可靠依据。Objective To investigate the CT diagnosis,pattern and distinguish diagnosis of Lumbar posterior marginal intraosseous cartilaginous node （LPMN）,to improve the knowledge of LPMN. Methods Clinical behaves and CT findings of 53 cases LPMN were analysed retrospectively. Results CT represent that a defect in the posterior superior margin of the affected vertebral body, with abnormity margin,differ in dimension, CT value is equal to lumbar disc in same lay,have sclerosis strip in differ thick,posterior to the defect,a bony fragmert was seen protruding into the spinal canal, in whole or in part with vertebral separation or not. According to the completeness cartilage nodules posterior can be divided into the type with continuity of the cartilage （28,accounting for 44.44%） and the type discontinuity of the cartilage（35,accounting for 56.56%）. Conclusion CT examination can provide unambiguous diagnosis of LPMN and reliable evidence for planning treatment protocol.
