目的分析半侧巨脑畸形胎儿的产前超声声像图特征,以提高对半侧巨脑畸形的认识。方法对1例双胎之一左侧侧脑室扩张的胎儿行产前超声检查,超声诊断为半侧巨脑畸形,行产前MRI检查确诊。结合产后新生儿头颅超声及CT检查结果进行对比分析。结果半侧巨脑畸形胎儿产前超声特征主要为:一侧大脑半球增大,大脑皮质增厚,病变侧侧脑室增宽,脑中线向对侧偏移,并可合并病变同侧小脑半球、脑干增大。结论产前超声诊断半侧巨脑畸形具有可行性,对有怀疑的胎儿结合产前MRI可以确诊。
Objective To analyze the characteristics of prenatal ultrasonography of the fetuses with hemifacial abortion, so as to improve their understanding of the hemifacial malformations. Methods Prenatal ultrasound was performed on one fetus with left ventricular dilatation in one of the twins. The ultrasound was diagnosed as a half giant brain deformity. Prenatal MRI examination was performed. Combined with postnatal neonatal head ultrasound and CT examination results were compared. Results The features of prenatal ultrasound in fetal hemifacial malformations were as follows: increased hemisphere on one side, thickened cerebral cortex, widened lateral ventricles on the side of the lesion, shifted to the contralateral side of the midline of the brain, combined with lesion on the same side of the cerebellum, Brain stem increased. Conclusion Prenatal ultrasound diagnosis of hemifrontal giant brain degeneration is feasible, for suspected fetal prenatal MRI can be diagnosed.
