摘要

本文除对186例幕上脑梗塞（包括缺血性梗塞、腔隙性梗塞及出血性梗塞）的CT资料作了回顾性分析外

还着重对另12例幕上梗塞进行了前瞻性连续随访CT观察。作者将某些缺血性梗塞在平扫时存在的皮层等密度表现称为“皮层回避征”

并证明这种表现可见于梗塞灶形成后及其演变的全过程

还对其机理和意义作了讨论

Abstract

CT scans of 180 cases of supratentorial infarction (including ischemic

lacunar and hemor-rhagic infarcts) were retrospectively analyzed. And other 12 cases were prospectively studied. On plain CT scans

the feature of isodensity of the cortex in some(18.4%) of ischemic infarction is called by the authors the "cortical sparing"

and proved to be a constant phenomenon during the evolution of the infarcts. The mechanism and importance of the cortical sparing is discussed. Fogging effect was also discovered during the fourth week of infarctions. The first week after attacks could be one of the peak periods when the infarcts hemorrhaged. In view of the fact that hemorrhagic infarctions most frequently occured in cerebral embolism and some cases had not apparent changes of clinical manifestations when they hemorrhaged

the authors put forward that it is important to give the patients a timely CT reexamination.The general CT manifestations of cerebral infarction were also analyzed and discussed
