超声对胎儿颅内囊性改变的诊断价值

Value of ultrasonic diagnosis for fetal intracranial cystic change

目的:探讨超声对胎儿颅内囊性改变诊断中的应用价值。方法:收集在本院超声检查中疑似为胎儿颅内囊性改变的92例患者的资料,以核磁共振成像(MRI)检查结果或引产后尸体解剖确诊,并与新生儿头颅超声结果对照。结果:92例胎儿颅内囊性改变的患者中,超声正确诊断单纯性脑室轻度扩张47例,脑积水7例,室管膜下囊肿6例,颅后窝池增宽7例,脉络膜囊肿6例,蛛网膜囊肿3例,胼胝体缺失8例,Dandy-Walker畸形2例,颅内出血1例,脑穿通畸形1例。结论:超声检查是诊断胎儿颅内囊性改变较直观、可靠的影像学方法。

Objective： To explore the application value of ultrasound in the diagnosis of fetal intracranial cystic lesions. Methods： A total of 92 fetuses with intracranial cystic lesions were encountered with ultrasound, combined with magnetic resonance imaging （MRI）. Results： Among 92 fetuses with intracranial abnormalities, there were 48 cases of ventricular dilatation, 7 cases of hydrocephalus, 6 cases of subependymal cysts, 7 cases of widened cisteme magna, 6 cases of chorioid plexus cysts, 3 cases of arachnoid cysts, 8 cases of agenesis of corpus eallosum, 2 cases of Dandy-Walker malformation, 2 cases ofintracranial hemorrhage, 1 case ofporencephalic cyst. Conclusion： Ultrasound is a direct and reliable measurement in diagnosis of fetal intracranial cystic lesions.
