摘　　要：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 evaluate the correlation between CT manifestations of lumbar intervertebral disk displacement with posterior marginal Schmorl's node and pathological findings of surgery sample. Materials and Methods: Retrospective analysis of CT manifestations was made in 35 cases suffering from lumbar intervertebral disk displacement with posterior marginal schmorl's node. Results: Of them 25 cases to locate at the posterior inferior margin of the vertebral body, and 10 cases at the posterior superior margin: 9 cases posteri-or-centrally, and 26 cases posterior-paracentrally. The findings of typical CT showed a round-like or multicystic defect with sclerotic rim at the posterior margin of vertebral body and the back wall of lumbar vertebrum protruding into the spinal canal. Conclusions: CT could accuratly reflect the pathologic changes of lumbar intervetebral schmorl' s node and show the integrality of ring of fibrocartilage.
