目的分析新生儿缺氧缺血脑病(HIE)的CT表现,加深对本病的认识。方法对临床诊断为新生儿缺氧缺血脑病并在我科作CT检查的患儿结合临床资料进行回顾性分析。结果根据病变范围分为轻度、中度、重度三型。轻度28例,脑白质呈片状低密度,分布1-2个脑叶,低密度区CT值16-19HU,脑室脑池脑沟正常;中度8例,脑白质低密度超过2个脑叶,低密度区CT值14-17HU,脑灰白质分界模糊,合并蛛网膜下腔出血2例、室管膜下出血1例,基底节、小脑密度正常;重度10例,脑白质呈弥漫性低密度,脑灰白质分界消失,低密度区CT值14HU以下,基底节、小脑密度略低,其中合并蛛网膜下腔出血8例、脑内出血6例、室管膜下出血1例,脑沟脑池脑室受压变窄。结论CT扫描可清楚显示病变范围、密度与并发症,是确诊HIE的有效方法。
Objective To analyze the CT findings of neonatal hypoxic-ischemic encephalopathy (HIE) and deepen the understanding of this disease. Methods Clinical data of neonates with hypoxic-ischemic encephalopathy diagnosed in our department and CT examination in our department were retrospectively analyzed. Results According to the lesion is divided into mild, moderate, severe type III. Mild 28 cases, the white matter showed low sheet density, distribution of 1-2 lobes, low density CT value of 16-19HU, brain cisterna groove normal; moderate in 8 cases, the white matter of low density more than 2 brain Leaf, low density CT value 14-17HU, fuzzy boundaries of gray matter, with subarachnoid hemorrhage in 2 cases, subependymal hemorrhage in 1 case, basal ganglia, cerebellum density normal; severe in 10 cases, diffuse white matter Low-density, gray-white matter boundaries disappear, low-density CT value below 14HU, basal ganglia, cerebellum density is slightly lower, including 8 cases of subarachnoid hemorrhage, intracerebral hemorrhage in 6 cases, 1 case of subependymal hemorrhage, sulci Cerebral pool ventricles narrowed. Conclusion CT scan can clearly show the extent of lesions, density and complications, is an effective method of diagnosis of HIE.
