Computerized tomography of cerebral infarction

Abstract

In 120 cases of patients with cerebral infarction, the affected areas in the CT images were analyzed with special reference to the site, the size, and the extension. Moreover, on 39 scans of 34 cases examined with 8 weeks after the onset of strokes, the CT images were analyzed from the viewpoint of the presence of a mass effect, edema, contrast enhancement, and the accompanying hemorrhage. From these investigations, the authors have obtained the following results; 1) The greatest incidence of infarcts was in the area supplied by the middle cerebral artery (57% of the cases), and, among those, the area of the lenticulostriate arteries showed the highest incidence (53%). Even in the posterior fossa, infarcts were found in 6% of the cases. These findings are coincident with those in autopsied cases. 2) Putaminal infarcts and infarctions occurring in the area supplied by the calcarine artery seemed to be uniformity of the arcuate pattern. 3) Most of the infarcts in the perfusion area of the anterior cerebral artery and the basal ganglia were found to be small and multifocal; they were thought to correspond with water-shed and/or lacunar infarcts. 4) In approximately 25% of the cases examined within 8 weeks  More>>

In conclusion, the presence of a mass effect, accompanying hemorrhage, and contrast enhancement detected by CT should lead us to reconsider the conventional management of cerebral infarction.}
