摘要(Abstract):

本文分析了452例脑梗塞的CT表现。其中缺血性脑梗塞438例,出血性脑梗塞14例。其表现随发病时间、梗塞类型和部位不同而异。分析了15例误诊漏诊原因。提出了脑梗塞的早期CT征象:(1)略低密度灶,边缘不清;(2)大脑皮质髓质分界不清;(3)豆状核轮廓模糊;(4)局部脑沟消失,脑池、脑室受压变窄或移位;(5)选择性强化;(6)沿大脑中动脉主干分布的点状密影。还着重讨论了脑梗塞的CT诊断、鉴别诊断和早期诊断。
The CT finding were investigated in 452 cases with cerebral infarction. Cf which 438 cases were ischmic, the others were hemorrhagic. The CT findings varied with onset time, type and location of the infarctions. Early CT findings were: 1. Slight hypodense lesion with ill-defined border; 2. Not demarcated between the grey and white mater; 3. Obscuration of the lentiform nucleus; 4. Absence of local sulci, compression and displacement of the ventricles; 5. Selective enhancement of lesions; and 6. Point dense shadow along the trunk of the middle cerebral artery. The causes of misdiagnosis were analysed. The CT diagnosis and differentiation of cerebral infarction were discussed also.
