A 21-year-old woman had recurrent progressive weakness/hypesthesia and pain in both lower extremities. At the age of 5 and 19 years, she had undergone surgical resection of a lipomyelomeningocele at L5-S1. Surgical exploration revealed that the cord was tethered and pulled over to the side by an excessively short right S-1 nerve root. The contralateral L-5 and S-1 nerve roots were markedly stretched. Division of the right S-1 nerve root resulted in prompt disappearance of pain in the lower extremities and improvement in neurological function.
一名21岁女性双下肢反复出现进行性无力/感觉减退及疼痛。5岁和19岁时，她曾接受L5 - S1节段脂肪瘤型脊髓脊膜膨出的手术切除。手术探查发现脊髓受栓系，被过度短小的右侧S1神经根牵拉至一侧。对侧的L5和S1神经根明显拉长。切断右侧S1神经根后，下肢疼痛立即消失，神经功能得到改善。
