目的：探讨脊髓纵裂的MSCT和MRI影像学特征及诊断价值。方法回顾性分析13例经临床证实的脊髓纵裂的MSCT及MRI影像学表现。结果本组Ⅰ型12例，均为骨性间隔，其中完整性骨性间隔10例，不完整性骨性间隔2例；Ⅱ型1例，为纤维性间隔；同时可分别伴有脊柱畸形、背侧皮窦、脊髓栓系及椎管内皮样囊肿等畸形。MSCT横轴位及MPR可清楚显示骨性间隔的部位、形态、走向、范围及椎体、椎板畸形等情况。MRI可以明确纵裂间隔的位置、形态、分裂脊髓是否位于同一硬膜囊内、脊髓圆锥位置、终丝情况及伴发病变。结论 MSCT及MRI联合应用可以对脊髓纵裂及伴发的其他畸形做出明确诊断。

Objective To study the features and diagnostic value of MSCT and MRI in diastematomyelia. Methods MSCT and MRI imagings of 13 patients with diastematomyelia proved clinically were analyzed retrospectively. Results Of the 13 cases,12 cases were type I ,both osseous septum,included complete form of osseous septum (10cases),incomplete esseous septumm (2cases);1 case was type II,with fibrous septum.All the cases were accompanied by spinal deformity,dorsal cutaneous sinus,tethered cord and endothelial cyst. MSCT axial and MPR can clearly show the location,shape, alignments, range of the osseous septum and vertebral deformities. MRI can clearly diagnose whether split spinal is in one single dural sac, the location and shape of the interhemispheric interval, conus position, the end of wire and concomitant lesions. Conclusion MSCT combined with MRI can make an accurate diagnosis in diastematomyelia(DM).
