In two cases of mobile tumours in the lumbar spinal canal there was difficulty and delay in clinical and radiologic diagnosis because the early symptoms did not correspond to any particular dermatome. Myelography and computed tomography (CT) are the initial diagnostic procedures used in most institutions, even where magnetic resonance imaging (MRI) is available. The purpose of these 2 case reports is to remind clinicians that it is possible for certain tumours attached to the roots in the lumbar spinal canal to migrate, because the roots tend to be redundant or tax. Multilevel search is essential in neuroradiologic studies for early diagnostic confirmation of mobile tumours.
在两例腰椎管内可移动肿瘤的病例中，临床和放射学诊断存在困难且延迟，因为早期症状与任何特定皮节均不对应。脊髓造影和计算机断层扫描（CT）是大多数机构使用的初始诊断程序，即使在有磁共振成像（MRI）的地方也是如此。这两篇病例报告的目的是提醒临床医生，腰椎管内某些附着于神经根的肿瘤有可能发生迁移，因为神经根往往多余或迂曲。在神经放射学研究中进行多级搜索对于早期确诊可移动肿瘤至关重要。
