目的探讨平山病临床表现,肌电图及影像学特点。方法对温州医学院附属第一医院2003年6月至2009年6月间确诊的8例平山病患者的临床表现,肌电图及影像学资料进行回顾性分析。结果 8例患者双侧上肢远端肌肉均呈神经源性损害,提示受损节段多在下颈髓前角细胞。8例颈部自然位MRI发现低位颈髓萎缩,屈曲位均发现颈髓前移,硬脊膜后壁前移,硬脊膜外间隙增宽。增强扫描中均可见不同程度的硬膜后间隙内异常强化影。结论根据平山病临床电生理及影像学检查显示平山病可能为下颈段脊髓病变,神经电生理检查与屈颈位MRI在平山病的诊断中有重要作用。
Objective To investigate the clinical manifestations, EMG and imaging features of Pingshan disease. Methods The clinical manifestations, EMG and imaging data of 8 cases of Pingshan patients diagnosed between June 2003 and June 2009 in the First Affiliated Hospital of Wenzhou Medical College were analyzed retrospectively. Results All 8 patients had neurogenic lesions on the distal muscles of both upper extremities, suggesting that the damaged segments were mostly anterior horn cells of the lower cervical spinal cord. 8 cases of cervical natural bit MRI found low cervical spinal cord atrophy, cervical spinal cord were found flexion forward, dural wall anterior adduction, epidural space widened. Enhancement scan can be seen in varying degrees of abnormal enhancement within the dural gap enhanced shadow. Conclusion According to the clinical electrophysiological and imaging findings of Pingshan disease, Pingshan disease may be the lesion of lower cervical spinal cord. The neuroelectrophysiological examination and MRI of flexor cervicalis play an important role in the diagnosis of Pingshan disease.
