摘　　要：目的:探讨多系统萎缩(MSA)的MRI、EMG、EAS-EMG特点和诊断要点。方法:回顾性分析16例MSA患者的临床资料。结果:MSA临床最常见的症状和体征依次是小脑、锥体外系、自主神经症状和体征;头部MRI可见延髓、脑桥、小脑中脚、小脑蚓部或小脑半球萎缩及桥延池、第四脑室扩大,部分可见特异性脑桥十字征或壳核裂隙征;EMG、EAG-EMG可见失神经电位。结论:结合MRI、EMG、EAS-EMG检查结果可提高对本病的诊断率。Objective ： To explore the clinical features and characteristics of magnetic resonance imagine （ MRI）, electro- myography （EMG） and external anal sphincter electromyography （EAS -EMG） and diagnostic criteria of multiple system atro- phy （MSA）. Methods： Clinical data of 16 patients diagnosed as MSA were restrospectively analyzed. Results： The sites affected by MSA in order are cerebellum, extrapyramidal system and autonomic system. MRI of the brain showed the atrophy of medulla oblongata, pons, middle cerebellal peduncle, cerebellar vermic or eerebellal hemisphere and the enlargement of the pontobulbar poll and fourth ventricle. Cross sign or putamen cranny sign were also shown in some patients. Denervated potentials were exam- ined in EMG and EAS - EMG. Conclusion： Combination of findings in MRI, EMG and EAS - AMG can raise the diagnostic level of MSA.
