An Analysis of CT Scans of Subcortical Arteriosclerotic Encephalopathy

Computerized tomograms (CT scans) of 62 cases of subcortical arteriosclerotic encephalopathy have been analysed. The results were: All 62 cases showed scattered or fused low density at the sides of both lateral ventricles and the white matter of the deep half-oval center. 54 cases showed enlargement in both lateral ventricles and brain cisterna and the third ventricle. 13 cases showed locular infarcts in thalamus and basal ganglia. 3 cases showed small focal cerebral hemorrhage. Generally it won't be difficult for CT diagnosis of subcortical arteriosclerotic encephalopathy,in combining with clinical features.
