急性脑桥梗死致发作性偏侧肌张力障碍一例

摘要

目的肌张力障碍是一组由骨骼肌的主动肌和拮抗肌不协调、间歇性地持续收缩造成的不自主运动和异常扭转姿势的症状群[1].方法传统观点认为肌张力障碍多由基底节病变所致.近期国外研究显示:脑干病变可导致眼睑痉挛和颅面部肌张力障碍[2］.结果偏侧肌张力障碍多是由于基底节和丘脑病变所致[3].结论急性脑桥梗死导致发作性偏侧肌张力障碍尚属少见,今对我院收治1例临床表现、影像学检查及病程转归进行总结.%Objective Dystonia is a medically intractable condition characterized by involuntary twisting movements and/or abnormal postures.Methods Traditional ideas that dystonia was much by basal ganglia pathological change.The recent foreign research showed that:the brainstem lesions could cause eyelid spasm and cranium facial dystonia.Results Hemidystonia was frequently due to an underlying structural lesion in the basal ganglia and thalamus.Conclusion Acute pontine infarct cause hemidystonia is still is rare,today in our 1 cases were clinical,neuroradiological features and course of disease outcome was summarized.
