目的探讨腰椎椎体后缘软骨结节的CT诊断价值。方法回顾性分析36例腰椎椎体后缘软骨结节的临床表现和CT特征。结果典型的腰椎椎体后缘软骨结节影像改变为:①椎体后上缘或后下缘类圆形骨质缺损,边缘致密硬化;②缺损后方骨块突入椎管,完全游离或部分与椎体相连;③硬膜囊及神经根受压;④多伴有椎间盘突出并造成椎管狭窄。结论CT检查能明确诊断腰椎椎体后缘软骨结节,为临床制订治疗方案提供可靠依据。 Objective To investigate the value of CT in the diagnosis of lumbar tracts cartilage nodules. Methods The clinical features and CT features of 36 cases of traumatic cartilage nodules in the lumbar vertebra were retrospectively analyzed. Results The typical lumbar vertebral tracts cartilage nodules changed as follows: ① vertebral posterior or posterior lower edge of the round bone defects, the edge of the dense sclerosis; ② defect behind the bone into the spinal canal, completely free or part of Vertebral body connected; ③ dural sac and nerve root compression; ④ often accompanied by disc herniation and cause spinal stenosis. Conclusion CT examination can clearly diagnose the cartilaginous nodules of the lumbar vertebral body and provide a reliable basis for clinical treatment plan.
