脑叶出血又称皮质下白质出血。过去认为其发病率低,国内报告为3.8％,国外报告为5％～10％,一般症状轻、不典型,在临床上较难与其它出血性疾病相鉴别,因而一直没有受到足够的重视。自从CT问世以来,许多神经病学者发现,这类疾病并非少见,有人提出其发病率在15％～34％之间,仅次于壳核出血。有人在180例CT扫描脑出血中,发现基底节出血114例(63.3％),脑叶出血32例(17.8％),占出血的第二位。同时还发现,青年人较多发生,因此,这类疾病越来越受到重视。本文主要收集1980～1986年国内外发表的30余篇文章,对 Lobe bleeding, also known as cortical white matter bleeding. In the past that its incidence is low, the domestic report was 3.8%, foreign reports of 5% to 10%, the general symptoms of mild, atypical, clinically more difficult to differentiate from other hemorrhagic diseases, and therefore has not been given enough attention. Since the advent of the CT, many neurologists have found that such diseases are not uncommon. Some have suggested that their incidence is between 15% and 34%, second only to putamen. Some people in 180 cases of CT scan of cerebral hemorrhage, found in the basal ganglia hemorrhage in 114 cases (63.3%), cerebral hemorrhage in 32 cases (17.8%), accounting for the second bleeding. At the same time, it is also found that more young people occur. Therefore, these diseases have drawn more and more attention. This article mainly collected more than 30 articles published from 1980 to 1986 at home and abroad
