Abstract
目的:研究急性脑桥旁正中梗死(Paramedian pontine infarction,PPI)的临床与影像特点。方法:回顾性分析新发脑桥旁正中梗死病例35例,发病后24 h内完成头颅磁共振(Magnetic resonance imaging,MRI)及磁共振血管成像(Magnetic resonanceangiography,MRA)检查,经磁共振弥散加权成像(Diffusion-weighted imaging,DWI)检查证实为急性PPI,研究其临床与影像特点。结果:PPI临床表现为各种腔隙综合征,早期运动障碍易加重且神经功能预后较差,多遗留轻至中度残障。MRA发现基底动脉轻中度狭窄。结论:PPI易发生早期运动障碍,PPI梗死灶形成可能与基底动脉病变有关。
