摘要 孕妇32岁,孕2产1,2015年11月13日孕24周+3在扬州大学医学院附属淮安市妇幼保健院行产前系统超声筛查提示胎儿半侧巨脑畸形(hemimegalencephaly,HME)。早孕期无病毒感染,无烟酒不良嗜好。既往体健,已生育1子,体健,无家族遗传病史。本次超声检查示胎儿双顶径8.18 cm (相当于孕32周+6),头围30.0 cm(相当于孕33周+2),腹围21.8 cm(相当于孕26周+2),股骨长径4.7 cm(相当于25周+5);胎心搏动规律,羊水最大暗区6.8 cm,胎盘位于前壁,成熟度0级;胎儿脊柱排列整齐,心、肺、肝脏、胃泡、双肾及膀胱未见明显异常;颅骨光环完整,脑中线不居中,中线偏向左侧,右侧大脑半球及小脑半球较左侧明显增大(图1),右侧脑室扩张,右侧脑室后角宽1.7 cm,右侧脑室前角宽1.3 cm,左侧脑室后角宽0.69 cm,第三脑室增宽,透明隔腔未显示,上唇连续。超声提示胎儿HME可能,建议MRI进一步检查。
