【摘要】 目的:分析脑裂畸形的CT和MRI表现,提高对该病的认识。方法:回顾性分析24例脑裂畸形的CT及MRI资料,单纯CT检查15例,MRI 4例,CT+NRI5例。结果:本组融合型9例,分离型15,单侧18例,双侧6例。特征性表现为灰质内衬横跨大脑半球的裂隙,外端增宽呈喇叭状蛛网膜下腔连接;内端多与侧脑室外壁局限性峰状突起相连。结论:CT和MRI能清楚显示脑裂畸形的病理特征,检查时应首选CT,必要时行MRI检查。更多还原

【Abstract】 Objective:To analyze CT and MRI findings of schizencephaly and to improve the knowledge of it.Methods:24 cases of schizencephaly were analyzed retrospectively. 15 cas es underwent CT scanning, 4 cases underwent MRI scanning 5 cases underwent CT and MRI scanning. Results:There were 9 cases of pattern of filsion and 15 cases of pattern effusion,18 cases of unilateral clefts and 6 cases of bilateral clefts. The characteristic CT and MRI findings was a trans-cerebral cleft which was lined by gray matter . The cortical side of fissure constantly was a trumpet-shaped CSF cavity and the ventricular side usually was a diverticulum defect of the lateral wall of the ventricle. Conclusion: CT and MRI can clearly demonstrate the pathology characters of schizencephaly, we recommend CT examination firstly, necessary MRI.更多还原
