摘要硬膜内腰椎间盘突出是一种罕见的病理实体。硬膜内腰椎间盘突出的发病机制尚不清楚。硬膜内椎间盘突出通常发生在L4-L5节段，但也有其他节段的报道。然而，L5-S1的硬膜内椎间盘突出是相当罕见的。在英文文献中大约有9篇关于L5-S1椎间盘突出的报道。我们描述了一个61岁的男性，怀疑硬膜内肿块在L5-S1空间水平。患者表现为腰背部和双下肢疼痛4个月，症状突然加重3天。钆增强磁共振成像（MRI）显示L5-S1水平的大椎间盘突出伴硬膜内成分。行L5和S1椎板切除术，硬脑膜肿胀且不活动。随后进行硬膜切开，取出硬膜内椎间盘碎片。患者3个月后完全康复。硬膜内腰椎间盘突出必须考虑在鉴别诊断肿块病变在椎管。增强MRI扫描有助于区分椎间盘突出与椎间盘间隙感染或肿瘤。
Intradural lumbar disc herniation is a rare pathological entity. The pathogenesis of intradural lumbar disc herniation is not known clearly. Intradural disc herniations usually occurred at the L4-L5 levels but have also been reported at other levels. However, intradural disc herniation at L5-S1 is quite rare. There are approximately nine reports in the English literature of intraradicular disc herniation at L5-S1. We described a 61-yr-old man with suspected intradural mass at the level of L5-S1 space. The patient presented with pain in the lower back and both lower legs for 4 months and a sudden exacerbation of the symptoms for 3 days. Gadolinium-enhanced magnetic resonance imaging (MRI) demonstrated a large disc herniation at the L5-S1 level with an intradural component. L5 and S1 laminectomy was performed, and dura was swollen and immobile. Subsequent durotomy was performed and an intradural disc fragment was removed. The patient had full recovery in 3 months. Intradural lumbar disc herniation must be considered in the differential diagnosis of mass lesions in the spinal canal. Contrast-enhanced MRI scans are useful to differentiate a herniated disc from a disc space infection or tumor.
