不典型脑桥梗死的临床表现与影像学特征分析

Clinical manifestation and radiologic characteristic of atypical pontine infarction

目的总结不典型脑桥梗死的临床表现与影像学特征。方法采用回顾性研究设计,选取128例诊断为脑桥梗死的患者(不典型108例),同时选取128例大脑半球脑梗死患者,比较两种疾病患者其临床体征的异同。分别予CT及MRI DWI检查。结果脑桥梗死组临床表现与大脑半球脑梗死类似,但也有差异。主要表现为头晕或眩晕发生率高,中枢性舌面瘫轻、失语轻、病理征少且病情容易进展。MRI DWI在对脑桥梗死的检查中具有明显的优势。结论脑桥梗死患者临床表现不典型,易诊断为大脑半球脑梗死,使用MRI DWI检查要优于MRI T1 T2及CT。

Objective To summarize the clinical manifestation and radiologic characteristic of atypical pontine infarction. Methods Retrospective analysis was adopted, 128 patients with pontine infarction （including 108 atypical patients）were selected, and selected another 128 patients with hemicerebrum infarction, compared clinical signs of these two diseases. All the patients received CT and DWI examinations. Results Clinical manifestations of pontine infarction group were similar to hemicerebrum infarction group, the main differences of two diseases were that pontine infarction had higher incidence of dizziness, slighter central lingual surface paralysis and aphasia, less symptoms but easier to progress. MRI DWI had obvious advantages in examination of pontine infarction. Conclusions Clinical manifestations of pontine infarction patients are atypical, which is tend to be diagnosed as hemicerebrum infarction, and MRI DWI better than MRI T1 T2 and CT in examination.
