摘要
目的：分析ＭＲＩ对Ａｒｎｏｌｄ－Ｃｈｉａｒｉ畸形的诊断价值及枕大孔前后径、小脑扁桃体垂直径同该病的关系。材料与方法：回顾性分析４４例ＣｈｉａｒｉⅠ型畸形的ＭＲＩ表现。选择４４例经ＭＲＩ证实的正常病例作为对照组，测量所有病例的枕大孔前后径及小脑扁桃体垂直径，采用ｔ检验进行统计学分析。结果：本组中８２％（３６／４４）有不同程度的脊髓空洞症，７７％（３４／４４）有延髓的拉长疝出，２５％（１１／４４）合并骨质发育异常。两组之间枕大孔前后径无显著性差异（Ｐ＞０．０５），小脑扁桃体垂直径有高度显著性差异（Ｐ＜０．００１）。结论：ＭＲＩ是Ａｒｎｏｌｄ－Ｃｈｉａｒｉ畸形及其合并症的最佳诊断方法，小脑扁桃体垂直径增大对诊断有重要价值。
To evaluate MRI in diagnosing the Arnold-Chiari malformation,and analyse the relationship between Arnold-Chiari malformation with the anteroposterior diameter of the foraman magnum(APDFM) or the vertical diameter of the celleblar tonsil(VDCT).Materials and Methods:The MRI appearences of 44 cases of Chiari Ⅰ malformation were analvsed retrospectively and 44 normal cases verified by MRI were used as controls.The APDFM and VDCT were measured in all cases.t test was used statistically.Results:82%(36/44) patients had a variable degree of syringohydromyelia,77%(34/44) had an elongated and herniated medulla,and 25%(11/44) were associated with bony anormalies of cranioverterbral junction.The difference of the APDFM between two groups was of no significance(P>0.05),the difference of the VDCT was very significant(P<0.001).Conclusion:MRI is the best method in the diagnosis of Arnold-Chiari malformation and its complications.We belived that the enlargement of the VDCT was of significant diagnostic value.
