CONTEXT
Lumbar intradural disk herniation (IDH) is a rare but serious complication of spinal disk protrusions. Although the pathogenesis of lumbar IDH is still vague, it is believed to be associated with the adhesion of the posterior longitudinal ligament with the ventral wall of the dura. Diagnosis is still difficult despite current neuroradiologic imaging techniques.
FINDINGS
Two women, ages 63 and 69 years, presented with recent exacerbation of back pain. In each case, imaging studies revealed a ventral herniated disk at L1-L2. Both patients underwent surgery and in both cases a hard mass was palpated through the dura. Both patients experienced immediate postoperative relief of back pain following surgery. One patient required fusion and postoperative rehabilitation; her neurologic deficit returned to baseline.
CONCLUSION/CLINICAL RELEVANCE: Prompt surgical intervention is indicated for IDH; disk removal allows for symptomatic relief and minimization of neurologic deficit.
背景
腰椎硬膜内椎间盘突出症（IDH）是椎间盘突出症的一种罕见但严重的并发症。尽管腰椎IDH的发病机制仍不明确，但一般认为它与后纵韧带与硬脊膜腹侧壁的粘连有关。尽管目前有神经放射成像技术，但诊断仍然困难。
研究结果
两名女性患者，年龄分别为63岁和69岁，近期出现背痛加重症状。在每例病例中，影像学检查均显示L1-L2水平有腹侧椎间盘突出。两名患者均接受了手术，术中均通过硬脊膜触及一个硬块。两名患者术后背痛均立即缓解。一名患者需要进行融合手术及术后康复治疗；其神经功能缺损恢复至基线水平。
结论/临床意义：IDH需及时进行手术干预；摘除椎间盘可缓解症状并使神经功能缺损降至最低。
