Abstract

Posterior migration of a sequestered disc fragment to the posterior epidural space is extremely rare due to the natural anatomical barriers of the thecal sac. Only cases were reported in the literature. It often causes severe neurological impairment, such as cauda equine syndrome. Accurate diagnosis is difficult because magnetic resonance images may mimic those of other more common posterior epidural mass lesions. We reported two cases of posterior epidural migration of sequestered discs. Both two patients responded well to operation with complete relief of symptoms.
隐匿性腰椎间盘后路硬膜外移位2例报告
由于硬膜囊的天然解剖屏障,分离的椎间盘碎片后向硬膜外腔后移是极为罕见的。文献中仅有病例报道。它经常引起严重的神经损伤,如马尾综合征。准确诊断是困难的,因为磁共振图像可能模仿其他更常见的硬膜外后路肿块病变。我们报告了2例后硬膜外移位的隔离椎间盘。两例患者手术反应良好,症状完全缓解。
