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 investigate the value of ultrasound in the diagnosis of fetal intracranial cystic changes. Methods: The data of 92 patients suspected of fetal intracranial cystic changes in our hospital were collected and diagnosed by MRI or autopsy. The results were compared with the results of neonatal head ultrasound. Results: Of the 92 patients with cystic cystic changes in fetus, the correct diagnosis of simple ventricles in 47 cases of mild ventricular expansion, hydrocephalus in 7 cases, subependymoid cyst in 6 cases, widened posterior fossa cistern in 7 cases, choroid 6 cases of cyst, 3 cases of arachnoid cyst, 8 cases of corpus callosum, 2 cases of Dandy-Walker malformation, 1 case of intracranial hemorrhage and 1 case of cerebral perforating deformity. Conclusion: Ultrasonography is an intuitive and reliable imaging method for the diagnosis of fetal intracranial cystic changes.
