目的探讨脑裂畸形的CT、MRI特征性表现及其临床诊断价值.方法回顾性分析17例脑裂畸形患者的临床CT、MRI的影像学征象.结果 17例脑裂畸形患者的CT、MRI图像表现为自皮质至侧脑室的横跨大脑半球的裂隙,裂隙两旁为内折的灰质;裂隙内侧端多为脑室外壁的幕状突起,闭合型裂隙外侧端呈小喇叭或深脑沟样形态,开放型裂隙内外侧端呈哑铃状.17例脑裂畸形患者中,单侧12例、双侧5例,共有24个裂隙;闭合型12例、开放型5例;合并透明隔缺如10例、灰质异位8例、一侧丘脑和部分基底节缺失2例、多小脑回畸形4例、巨脑回畸形1例、侧脑室三角区白质较少2例、蛛网膜囊肿5例.结论脑裂畸形具有特征性的影像学表现,CT、MRI检查能够清楚地显示脑裂畸形的病理解剖形态.

Objective To investigate the features and clinical diagnosis values of CT and MRI in schizencephaly.Methods The imaging features of CT and MRI were restrospectively analyzed in 17 cases of schizencephaly patients.Results CT and MRI showed the fractures from the cortex to the lateral ventricle which stretch across the brain hemisphere,and there were inflexed grey matter on both sides.In the inner end of fracture,there were some curtain like protuberance of the ventricle walls,the lateral end of closed type fracture presented a trumpet or deep sulci like shape,and the open type fracture presented a dumbbell shape.A total of 24 fractures were found in 17 cases of schizencephaly patients,12 cases were unilateral,5 cases were bilateral; 12 cases were closed type,5 cases were open type; 10 cases complicated with transparent septum defect,8 cases were heterotopic gray matter,2 cases were unilateral thalamus and partial basal ganglia defect,4 cases were polymicrogyria,1 case was pachygyria,2 cases were less white matter at the trigone of the lateral ventricles,5 cases were arachnoid cyst.Conclusion Schizencephaly has distinctive imaging features,CT and MRI examination can clearly display the pathological morphology of schizencephaly.
