Objective: White cord syndrome is extremely rare and search of the literature has revealed very few cases. Postoperative MR scan revealed hyperintense intrinsic cord signal changes within cord ischemia and edema. It is thought to be caused by reperfusion injury of the spinal cord. This is called white cord syndrome. This report is very rare case of ‘White Cord Syndrome’ with paraplegia after anterior cervical discectomy and fusion (ACDF). A 49-year-old woman presented with neck pain lasting for several months and second and third finger radiating pain. Severe cervical herniated intervertebral disc findings could be identified at C6–7 level on C-spine MRI. ACDF C6–7 surgery was performed. Immediately after the operation, physical examination revealed paraplegia and emergency MRI was performed. On MR images, T2 high signal myelopathy suspected as reperfusion injury at C6–7 level, and emergency surgery was performed under diagnosis of white cord syndrome. After the emergency operation, the paraplegic problem was gradually resolved. Before discharge, motor power and sensory deficit of bilateral lower extremity were fully recovered. Surgeons should explain the possibility of white cord syndrome before cervical decompression surgery and should perform a neurological examination immediately after surgery. We recommend that the importance of early recognition and prompt treatment of white cord syndrome.

病例报告：颈椎前路椎间盘摘除融合术后的白索综合征：及时诊断和治疗的重要性

目的：白索综合征非常罕见，文献检索显示极少的病例。术后MR扫描显示脐带缺血和水肿内高强度内在信号发生改变。据认为是由于脊髓再灌注损伤引起的。这称为白索综合征。该报告非常少见，在颈椎前路椎间盘切除融合术（ACDF）后出现截瘫的“白线综合症”。一名49岁的妇女表现出持续数月的颈部疼痛，第二和第三根手指放射出疼痛。在C型脊柱MRI上，可以在C6–7水平上发现严重的颈椎间盘突出症。进行了ACDF C6-7手术。手术后立即进行身体检查，发现截瘫并进行了紧急MRI检查。在MR图像上，T2高信号性脊髓病被怀疑为C6-7水平的再灌注损伤，并在诊断出白索综合征的情况下进行了紧急手术。紧急手术后，截瘫问题逐渐得到解决。出院前，双侧下肢的运动能力和感觉缺陷已完全恢复。外科医生应在宫颈减压手术前解释白索综合征的可能性，并应在手术后立即进行神经系统检查。我们建议早期识别和及时治疗白索综合征的重要性。双侧下肢的运动能力和感觉缺陷已完全恢复。外科医生应在宫颈减压手术前解释白索综合征的可能性，并应在手术后立即进行神经系统检查。我们建议早期识别和及时治疗白索综合征的重要性。双侧下肢的运动能力和感觉缺陷已完全恢复。外科医生应在宫颈减压手术前解释白索综合征的可能性，并应在手术后立即进行神经系统检查。我们建议早期识别和及时治疗白索综合征的重要性。
