目的探讨颈部MRI对平山病的诊断价值.方法回顾性分析临床确诊的平山病患者15例及15例正常自愿者的MRI图像,观察MRI图像上颈椎曲度、颈髓前后径及硬膜外信号有无异常.结果确诊平山病患者的颈椎曲度变直,颈髓第5颈椎至第1胸椎水平存在不同程度的萎缩,自然位35％的患者硬膜外间隙存在长T2信号,过屈位92％患者对应硬膜外间隙存在长T2信号,部分长T2信号内显示血管流空影.结论平山病患者在过屈位时颈髓形态及硬膜外异常信号极具特征性,颈部过屈位MRI在平山病诊断中具有重要价值.

Objective To investigate the MRI appearance and the value of cervical MRI in the diagnosis of Hirayama disease.Methods Imaging of 15 cases of hirayama disease confirmed clinically and 15 volunteers were analyzed retrospectively,and the cervical curvature,anterior-posterior diameter of the cervical cord,abnormal signals in the postrior epidural space were observed.Results Cervical curvature were straigtened,the spinal cords were mild atrophy in C5-T1 and anterior-posterior diameter of the cervical cords were short.Thirty - five percent of the epidural space of patients shown higher signal on T2WI in neck neutral position MRI scan,but 92 percent in neck flexion position MRI scan.Some curvilineal flow void signals appearred in higher signal on T2WI.Conclusions The cervical cord atrophy and abnormal signals of epidural cavity are characteritic manifetations on MRI.Neck flexion poition MRI play an important role in diagnosis of Hirayama disease.
