摘　　要：目的:加深对腰椎椎体后缘软骨结节的认识。方法:对31例腰椎椎体后缘软骨结节的临床和CT表现进行回顾性分析。结果:CT表现为腰椎椎体后缘类圆形、多囊状或不规则形的骨质缺损区,大小不一,位于椎体后缘正中或偏侧,其CT值等同于同层面的椎间盘,边界清楚,常有薄厚不一的硬化带,缺损区后方骨块突入椎管内,椎管狭窄(10例,占32.2%),硬膜囊受压(5例,占16.1%),可伴椎间盘突出(16例,占51.6%)。结论:CT扫描对腰椎椎体后缘软骨结节具有重要的诊断和鉴别诊断价值。Objective： To improve the knowledge of LPMN. Methods： Clinical behaves and CT findings of 31 cases LPMN were analysed retrospectively. Results： CT represent that a defect in the posterior superior margin of the affected vertebral body, with bursay, abnormity margin, differ in dimension, just in middle or side of posterior superior margin, CT value is equal to Lumbar disc in same lay, clarity in marginal, have sclerosis strip in differ thick, posterior to the defect, a bony fragment was seen protruding into the spinal canal, lumbral spinal canal stenosis（10 cases, 32.2 % ）, the dural sac and putamen bursa was compressed due to the bony fragment（5 cases, 16.1% ）, and Lumber disc herniation often combined（16 cases, 51.6 % ） . Conclusion： CT is important on diagnosis and distinguish diagnosis for lumbar vertebral posterior marginal cartilaginous node.
