目的:探讨脊髓多发性硬化与髓内其它疾病的鉴别。方法:回顾性分析7例被误诊为其它疾病的脊髓多发性硬化病例的临床及MRI特点。结果:7例病例在MRI表现为矢状位长T_1低信号长T_2高信号,呈长条状或跳跃性斑片状,长度小于3个椎体节段,T_2WI轴位为不规则斑片状高信号,多在脊髓背侧白质内。结论:通过MRI检查,结合临床病史,可将脊髓多发性硬化与髓内肿瘤及血管性病变、急性脊髓炎等鉴别。
Objective: To investigate the differential diagnosis of spinal cord multiple sclerosis and other intramedullary diseases. Methods: The clinical and MRI characteristics of 7 cases of multiple sclerosis of spinal cord misdiagnosed as other diseases were retrospectively analyzed. Results: The MRI findings of 7 cases were sagittal long T_1 low signal long T2 high signal, with long strip or jumpy patchy, the length was less than 3 vertebral segments, the T_2WI axis was irregular patchy High signal, mostly in the dorsal white matter. Conclusion: Through MRI examination combined with clinical history, multiple sclerosis and intramedullary tumors and vascular lesions, acute myelitis can be identified.
