目的：根据脊髓空洞症MRI的表现将其分类并观察其特点与疗效情况.方法：对123例脊髓空洞症患者（保守治疗观察81例、手术42例）临床及MRI表现进行病因分析.结果：123例脊髓空洞症患者中有66例单纯合并小脑扁桃体下疝,12例合并小脑扁桃体下疝及颅底发育畸形,3例合并小脑扁桃体下疝及纵裂畸形,3例合并脊椎侧弯及后凸畸形,9例合并脊髓脊膜彭出;11例合并肿瘤;12例有外伤史、其中6例脊椎骨折;7例合并脊髓拴系、圆锥低位.结论：MRI能直观全面显示脊髓空洞症范围和程度以及致病原因,为治疗提供指导性建议.

The appearances of syringomyelia in MRI (analysis of 123 cases)

Objective:To classify syringomyelia and see its features and effects of treatment by its MRI appearances.Methods:The causes of 123 patients with syringomyelia(81 cases with medicine treatment,42 cases with surgery)were analyzed by their clinical and MRI appearances.Results:In 123 patients with syringomyelia,there were 66 cases only with Arnold-Chiari malformation,12 cases with Arnold-Chiari and skull-base malformations,3 cases with Arnold-Chiari malformation and diastematomyelia,3 cases with spine bent in one direction and saddle-forward malformation,9 cases with myelomeningocele;11 cases with tumors;12 cases with injury history,including 6 cases of spine fracture;7 cases with tethered cord syndrome and spinal cord was terminated below L_2.Conclusion:MRI can directly and completely show the range,degree and causes of syringomyelia,thus give instructive suggestions to its treatment.
