Dorsal herniation of the spinal cord through the dura is an uncommon phenomenon and this is only the fifth reported case in the thoracolumbar spine, the first following surgery at the thoracolumbar junction.
A 57-year-old male underwent marsupialisation of a benign intramedullary cyst at the T12-L1 level and subsequently returned with symptoms of dorsal column compromise. He was found to have a posterior herniation of the cord into a pseudomeningocele at the level of the previous surgery.
The hernia was reduced surgically and the defect closed directly without the need for a dural patch leading to a full recovery. Posterior cord herniation, its possible aetiologies and management strategies are discussed.
硬脊膜后脊髓疝是一种罕见的现象，这是第五例胸腰椎段报告病例，也是首例胸腰椎交界处手术后的病例。
一名 57 岁男性在 T12-L1 水平进行了良性脊髓内囊肿的袋状切开术，随后出现后柱压迫症状。发现他的脊髓通过先前手术水平的假性硬脊膜囊肿向后疝出。
手术减少了疝出，直接关闭了缺损，无需使用硬脑膜补片，从而完全恢复。讨论了后索疝出的可能病因和治疗策略。
