摘  要:目的探讨孤立性脑桥旁正中梗死(PPI)的临床与MRI表现特点。方法回顾性分析该院2016年1月—2017年8月临床证实的20例PPI的病例资料,全部患者均行常规MRI检查,12例有MRA检查资料。结果临床主要表现为偏身瘫痪,偏身感觉缺陷,共济失调,眩晕、下咽困难、中枢性面瘫,1例表现为不宁腿综合征。MRI上均为单侧病灶,其中右侧12例,左侧8例。病灶均位于脑桥中线旁区域,呈T1WI低、T2WI及FLAIR高信号、DWI高信号、ADC低信号,以DWI序列显示最佳。12例MRA图像均可见基底动脉及其分支的狭窄。结论 PPI临床表现多样且无特异性,MRI(尤其是DWI序列)可早期明确诊断。Objective To study the clinical and MRI manifestation features of isolated paramedian pontine infarction.Methods 20 cases of PPI confirmed in our hospital from January 2016 to August 2017 were selected,all patients underwent the routine MRI examination,and 12 cases had MRA examination data.Results The major clinical manifestations were hemi-paralysis,hemisensory loss,asynergia,vertigo,dysphagia and central facial palsy,1 case showed restless leg syndrome,and single lesions were shown on MRI,including 12 right cases and 8 left cases,and the lesions were located in mid-upper paramedian pons,showing low T1WI,high T2WI and FLAIR,high DWI signal,low ADC signal,and the DWI sequence was the best,and the MRA images of12 cases showed stenosis of arteriae basilaris and their branches.Conclusion The clinical manifestations of PPI are multiple,and it has no specificity,and the MRI(especially DWI sequence)can be clearly diagnosed in the early stage.
