目的探讨脑干梗死的临床特征、病理基础及影像学特点,提高对本病的诊断及疗效。方法72例脑干梗死患者均经头颅CT和MRI确诊,并分析探讨本病的临床特点及疗效。结果延髓和中脑梗死均具有交叉性瘫痪,脑桥梗死则有不同的临床征象,可概括为四种类型:交叉性瘫痪、四肢瘫、纯偏身感觉障碍、偏瘫并偏身感觉障碍。结论脑干梗死的主要临床表现复杂多样,不典型病例早期诊断困难,MRI对脑干早期诊断最有意义,CT不能确诊脑干梗死,但有助于排除脑干出血。
Objective To investigate the clinical features, pathological basis and imaging features of brain stem infarction to improve the diagnosis and curative effect of this disease. Methods 72 patients with brain stem infarction were diagnosed by CT and MRI, and analyzed the clinical features and efficacy of this disease. Results The medulla oblongata and midbrain infarction had cross paralysis. There were different clinical signs of pontine infarction, which could be summarized as four types: cross paralysis, quadriplegia, pure partial sensory dysfunction, hemiparesis and partial sensory dysfunction. Conclusions The main clinical manifestations of infarction in brainstem are complex and diverse. Early diagnosis of atypical cases is difficult. MRI is of most significance in the early diagnosis of brainstem. CT can not diagnose brainstem infarction, but it can help to exclude bleeding of brainstem.
