摘　　要：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。Objective Study of clinical and radiographic features of acute Paramedian pontine infarction（PPI）. Methods A consecu- tive series of 35 patients with acute pontine infarction, who had magnetic resonance imaging （MR.I） and magnetic resonance angiography （MRA） within 24 hours of onset were enrolled in this study. They were confirmed of acute PPI with diffusion -weighted imaging （DWI）. Results The clinical features of PPI expressed as a variety of lacunar syndrome, early progressive motor deficits was common, poor progno- sis and possibility to be left with mild to moderate disabilities. Magnetic resonance angiography of basilar artery displayed mild to moderate stenosis. Conclusion The PPI patients are at higher risk of early progressive motor deficits . The Infarction may be associated with basilar artery disease.
