摘　　要：目的探讨超声检测新生儿胼胝体发育不良的声像特征及诊断价值。方法用超声对新生儿胼胝体进行扫查,共行头颅超声筛查3797例,观察胼胝体发育不良的超声图像特征,并行CT及MRI扫查。结果超声诊断12例胼胝体发育不良患儿,均再行CT或MRI扫查,证实11例存在胼胝体发育不良,其中完全性4例、部分性7例。声像图表现为中线结构上探测不到胼胝体或仅显示部分胼胝体,侧脑室分离伴角度扩大,第3脑室扩张并位置上移,双侧脑室横断面显示外弧度均有不同程度内弧度改变,呈牛头状,病变程度越重则内弧度化越明显,侧脑室纵轴切面呈水滴状,伴或不伴透明隔缺失。结论超声能准确诊断新生儿胼胝体发育不良并进行初步分类,对指导临床具有重要意义。Objective To study the acoustic image feature of neonatal corpus callosum dysplasia.Methods Using ultrasound to inspect corpus callosum, newborn corpus callosum dysplasia’s ultrasound image characteristics were observed, combined with the CT and MRI features inspection method to diagnosis.Results Ultrasound diagnosed 12 corpus callosum dysplasia children, both of them have been scanned by CT or MRI, and confirmed 11 cases of corpus callosum dysplasia among them, 4 cases completeness, 7 cases partiality.Ultrasonography manifest midline structures could’t dispaly corpus callosum or show the part of the corpus callosum, expand with Angle, third ventricle expansion and move up,cross section of the cerebral ventricles showed outside change in arc radian, like a bull＇s head, the lesion is more heavier, the radian more obvious, the lateral ventricle longitudinal axis like water drops, with or without the lack of septum pellucidum.Conclusion Ultrasound can accurately diagnose neonatal corpus callosum dysplasia and preliminary classification.
