目的:分析ChiariI型畸形(CMI)患者小脑扁桃体下疝程度与脊髓空洞症的关系。方法:回顾性分析我院1991～2001年142例CMI患者MR检查资料,其中伴发脊髓空洞症67例,无空洞症75例,测量小脑扁桃体下疝值,并对两组结果进行分析。结果:两组结果比较表明,小脑扁桃体下疝程度在空洞组与无空洞组间无差异。结论:ChiariI型畸形患者小脑扁桃体下疝程度与脊髓空洞症的发生无关。
Objective: To analyze the relationship between the degree of cerebellar tonsillar herniation and syringomyelia in Chiari-type deformity (CMI) patients. Methods: The data of MR examination of 142 CMI patients from 1991 to 2001 in our hospital were retrospectively analyzed. Among them 67 cases of syringomyelia and 75 cases of non-cavitary disease were measured. The results of two groups were analyzed. Results: The results of two groups showed that there was no difference in the degree of inferior cerebellar tonsillar hernia between the cave group and the cave-free group. Conclusion: The degree of cerebellar tonsillar herniation in patients with ChiariI deformity is not related to the occurrence of syringomyelia.
