研究设计：一例神经根内椎间盘突出症的病例报告。神经根内椎间盘突出症是一种特殊类型的硬膜内椎间盘突出症。在这份报告中，我们提出了第十例根内腰椎间盘突出症，并提出了一个新的分类硬膜内椎间盘herniations.Case报告：一个32岁的男性被送往医院经历了疼痛的下背部和右腿1个月入院前。神经系统检查显示拇长伸肌无力，Lasegue征阳性，右下肢踝反射减弱，双侧椎旁肌痉挛。磁共振成像（MRI）显示椎间盘突出，右侧L5-S1间隙水平有后外侧突出碎片。他接受了L5椎板切除术。术中发现右侧SI神经根肿胀且不活动。在右侧S1根的硬脑膜上做一个纵向切口，取出一个硬脑膜内游离椎间盘碎片，松解S1根。病人是免费的疼痛postoperation.Conclusion：我们建议一个新的分类硬膜内椎间盘突出症与这种不寻常的情况下介绍，并回顾文献的发病机制，临床表现，诊断和治疗。
Study design: A case report of intraradicular disc herniation. Intraradicular disc herniation is a special type of intradural disc hernations. In this report, we present the tenth case of intraradicular lumbar disc herniation and suggest a new classification for intradural disc herniations.Case report: A 32-year-old male was admitted to hospital having experienced pain in the lower back and right leg for 1 month prior to admission. Neurological examination revealed weakness of the extensor hallucis longus, positive Lasegue's sign, decreased ankle reflex in his right lower extremity, and bilateral paravertebral muscle spasm. Magnetic resonance imaging (MRI) revealed a disc herniation with a posterolateral extruded fragment on the right at the level of the L5-S1 space. He underwent L5 laminectomy. During the operation, the right SI root was found to be swollen and immobile. A longitudinal incision was made in the dura of the right S1 root and an intradural free disc fragment was removed, and the S1 root was relieved. The patient was free of pain postoperatively.Conclusion: We suggest a new classification for intradural disc herniations with this unusual case presentation and review the literature for pathogenesis, clinical picture, diagnosis and treatment.
