Intradural disc herniation is very rare. We describe a case of anterior transdural L4-L5 disc herniation presenting as a partial cauda equina syndrome without related back pain or history of back pain. MRI allowed presurgical diagnosis showing an irregular intradural mass that did not enhance. That lack of enhancement could be related to the fact that the disc herniation was relatively recent.
硬膜内椎间盘突出非常罕见。我们描述了一例经硬膜前路L4-L5椎间盘突出症，表现为部分马尾神经综合征，无相关背痛或背痛病史。磁共振成像（MRI）实现了术前诊断，显示出一个不规则的硬膜内肿块，无强化表现。这种无强化可能与椎间盘突出相对较新有关。
