摘　　要：目的：探讨多发性脑梗死的CT诊断与临床表现的关系。方法搜集2007年6月~2011年12月210例多发性脑梗死完整病例，通过CT表现，临床表现及血流动力学变化进行分析研究。结果多发性脑梗死CT影像表现2个以上脑实质低密度灶，CT值8~22Hu，腔隙脑梗死直径小于2cm，大面积脑梗死直径大于2cm，临床表现常为高血压、糖尿病、头痛、头晕、运动障碍、锥体束征、构音障碍，偏身感觉障碍，而腔隙状态表现不明显。梗死灶分布依次为脑室体旁，豆状核、外囊、小脑、中脑、大面积多位于颞顶叶，其次额叶。结论 CT诊断及临床表现均诊为多发脑梗死的符合率41.0%，多发性脑梗死CT表现与临床表现综合分析才能准确诊断。Objective To investigate the relationship between the CT diagnosis of freguently occurring cerebral infarction and its clinical manifeston. Methods The complete histories of 210 cases of frequently occurring cerebral infarction from June through December 2011 were collected and comparative analytical studies were done through CT manifestation, clinical manifestations and hemodynamic changes. Results The CT images of frequently occrring cerebral infarction showed more than two low clensity foci in cerebral substance, CT value 8-22Hu. The diameters of cerebral lacunar infarction were less than 2cm and those of large area cerebral infarction were larger than 2cm. The clinical manifestations often were hypertension, diabetes mellitus headache, dizziness, movement disorder, pyramidal sign, sound production disorder, hemiparethesia, while the manifestations of lacunar state were not apparent. The infarction foci were distributed in paraventricular area, lenticular nucleus, external capsule, celebellum and midbrain successfully. The large area foci were often located in temporoparietal lobe and next frontal lole. Conclusion The coincident rate in diagnosing frequently occurring cerebral infarction by CT diagnosis and clinical manifestations was 40.1%. Synthetical analysis of CT and clinical manifestations is necessary for accurate infarctions of frequently occurring cerebral infarction.
