摘要
目的:探讨脑卒中后锥体束继发性损害的常规磁共振(MRI)表现及意义。方法:连续性收录分析2007～2008年在我院住院治疗,首次发病,病程在7 d内,有单侧肢体偏瘫及中枢性面舌瘫等体征,分别在急性期(7 d)内及亚急性期(14 d)以后进行一次及以上头颅MRI检查,确诊为单侧基底节或放射冠区单一梗死灶或单一血肿的脑卒中患者的临床资料。结果:本组39例患者,其中脑出血13例,脑梗死26例,平均年龄(51.40±7.56)岁,均有肢体偏瘫的体征,并且在两次MRI检查之间神经功能逐渐恢复。所有患者第2次的MRI图像上,均在远离病灶的大脑脚、脑桥、延髓等一个或多个部位,相当于锥体束行程上出现大小不等、边缘不清的长T1短T2、或者长T1长T2的异常信号。结论:MRI可以检测到脑卒中后锥体束继发损害的现象,临床上注意脑卒中后病灶远端锥体束行程上出现异常信号,很可能就是其继发性损害表现,这对区分与新发脑梗死或炎症等其他病变有积极意义。
Objective:To investigate the secondary impairments of pyramidal tract after stroke and its significance. Methods:The clinical data of patients with an acute stroke with internal capsule or corona radiata and the findings of head magnetic resonance image(MRI) in acute and subacute stage were collected and analysed; respectively.Results:Thirty-nine patients with an average age of(51.40±7.56) years were recruited, 13 of them with cerebral heamorrhage and 26 with cerebral infarction.All patients had some degree...
