摘要
作者分析１００例脑白质稀疏症的临床、ＣＴ、ＭＲＩ及ＳＰＥＣＴ影像资料。发现其临床特征：为卒中反复发作并呈进行性进展（占４２％）、高血压（占６５％）、感觉或（和）运动障碍（占６３％）、智力及精神障碍（占２１％）。ＣＴ表现为大脑白质深部弥漫性不均匀低密度区，累及额叶（１００％）、枕叶（８５％）、顶叶（７０％）、半卵圆中心（６３％）及脑干（３％），并伴有不同程度脑室扩大、脑萎缩和多发性脑梗塞。在的ＭＲＩＴ＿２加权像上呈明显的高信号，Ｔ＿１加权像上呈等或低信号。作者对脑白质稀疏症的病因、病理、临床特征及诊断、鉴别诊断进行了讨论。
The authoes analyzed the CT,MRl and SPECT findings of 100 cases with diffuse white matter lucencies(leuko-araiosis).The clinical features included stroke 42%,hypertension 65%,dyskinesia or sensory disturbance 63%,dementia and mental disturbance 21%。CT image showed diffuse areas of inhomogeneous decreased density in deep white matter of cerebral hemi- spheres involving frontal lobes 100%,occipital 85%,parietal 70%,centrum semioval 63%and brainstem 3%together with varying degrees of dilatation of the lateral ventricles,atrophy of brain and multiple infarcts. Leuko-araiosis lesions exhibited markedly high signal intensity compared with brain on T_2 weighted image,while T_1 weighted image showed lower signal.The pathogenesis,pathology,clinical manifestations,diagnosis and differential diagnosis were discussed.
