目的:探讨椎后缘许莫结节型腰椎间盘突出的CT表现及与临床手术病理的关系。材料与方法:回顾性分析了35例椎后缘许莫结节型腰椎间盘突出的CT表现。结果:35例椎后缘许莫结节型腰椎间盘突出症,发生在椎后下缘25例,椎后上缘10例;中央型9例,旁侧型26例。CT表现:椎体后缘骨质呈类圆形或多囊状骨质缺损,周边硬化,后壁呈弧形突向椎管,有断裂、游离。结论:CT可反映椎后缘许莫结节型的病理变化,并可初步判断纤维环完整性。
Objective: To investigate the CT manifestations of the posterior edge of Xu Mo nodular lumbar disc herniation and its relationship with the clinical pathology. Materials and Methods: A retrospective analysis of 35 cases of posterior edge of Xu Mo nodular lumbar disc herniation CT manifestations. Results: 35 cases of posterior edge of Xu Mo nodular lumbar disc herniation occurred in 25 cases of posterior margin of the lower edge of the vertebral posterior margin in 10 cases; 9 cases of central type 26 cases of lateral type. CT manifestations: vertebral bone was round or multi-cystic bone defect, peripheral sclerosis, the posterior wall of the arc protruding to the spinal canal, a fracture, free. Conclusion: CT can reflect the pathological changes of the posterior margin Xu Mo nodules, and can initially determine the integrity of the annulus fibrosus.
