目的 提高对腰椎后缘软骨结节CT表现的认识。方法 回顾性分析39例腰椎后缘软骨结节的CT表现,11例与常规X线片比较。结果 CT表现为:①椎体后缘骨质缺损,密度与椎间盘相似,周边硬化。②缺损区后壁有突出椎管骨块,明显者可压迫硬膜囊及神经根并可致椎管狭窄。③多同时伴有椎间盘突出。结论 CT能明确诊断腰椎后缘软骨结节,并对制订治疗方案提供可靠依据。 Objective To improve the understanding of CT manifestations of lumbar trabecular cartilaginous nodules. Methods The CT findings of 39 cases with lumbar posterior margin cartilage nodules were retrospectively analyzed. Eleven cases were compared with conventional X - ray films. Results CT showed: ① vertebral bone defect, density and disc similar to the surrounding sclerosis. ② defects in the posterior wall of prominent spinal bone block, obviously can dural sac and nerve root compression and can lead to spinal stenosis. ③ more accompanied by disc herniation. Conclusion CT can confirm the diagnosis of lumbar tracts edge cartilage nodules, and provide a reliable basis for the development of treatment options.
