Abstract

In 114 patients with postrepair myelomeningocele MRI of the spine was performed. Tethered cord (89%) and associated malformations (syrinx, lipoma etc.) (33%) were the most important findings. Additional MRI scans of the head (44 patients) revealed numerous further anomalies. Arnold Chiari malformation was found in 76% of the patients (ACM I:32%, ACM II:44%). In the ACM II group compression of lower cranial nerves, brain stem, and cerebellum can lead to considerable neurologic symptoms. Therefore in patients with progressive neurologic dysfunction a complete investigation of the whole spine and brain is necessary. MRI proves to be the diagnostic procedure of choice in patients with dysraphic myelodysplasia.

摘要

对114例脊髓脊膜膨出修补术后患者进行了脊柱MRI检查。脊髓栓系（89%）和相关畸形（脊髓空洞症、脂肪瘤等）（33%）是最重要的发现。对44例患者进行的额外头部MRI扫描发现了许多其他异常。76%的患者发现有阿诺德-基亚里畸形（Ⅰ型阿诺德-基亚里畸形：32%，Ⅱ型阿诺德-基亚里畸形：44%）。在Ⅱ型阿诺德-基亚里畸形组中，低位颅神经、脑干和小脑受压可导致相当严重的神经症状。因此，对于有进行性神经功能障碍的患者，有必要对整个脊柱和脑部进行全面检查。MRI被证明是诊断脊柱裂性脊髓发育不良患者的首选诊断方法。
