Abstract

Background: There are very few reports of intradural disc herniations associated with achondroplasia described in the literature.

Case description: A patient with achondroplasia presented with progressive paraparesis attributed to a magnetic resonance-documented intradural disc herniation at the T12-L1 level occupying more than 90% of the spinal canal. It was successfully removed through a T12 laminectomy with durotomy; note a laminectomy would have been contraindicated if this had been an extradural anterior/anterolateral disc. Postoperatively, the patient progressively improved and, within 6 months, had 4/5 proximal/distal function and full sphincter control.

Conclusion: A patient with achondroplasia and an intradural T12/L1 disc herniation (i.e., unlike an extradural anterior/anterolateral thoracic disc) successfully underwent a decompressive laminectomy with near full resolution of their preoperative paraparesis.

一名软骨发育不全患者的 T12-L1 椎间盘突出症：病例报告。

背景：有关软骨发育不全引起的硬膜内椎间盘突出症的文献报道很少：一名软骨发育不全的患者出现进行性截瘫，原因是磁共振记录的T12-L1水平硬膜内椎间盘突出症占据了90%以上的椎管。通过 T12 椎板切除术和穹隆切开术，患者成功摘除了椎间盘；需要注意的是，如果患者患的是硬膜外前/后外侧椎间盘突出症，那么椎板切除术是禁忌症。术后，患者的病情逐渐好转，6 个月内，近端/远端功能达到 4/5，括约肌完全控制：结论：一名患有软骨发育不全和硬膜内T12/L1椎间盘突出症（即不同于硬膜外胸椎前/后外侧椎间盘）的患者成功接受了减压椎板切除术，术前偏瘫几乎完全缓解。
