A rare case of extramembranous pregnancy is reported. It was associated with intermittent loss of liquor and bloody discharge beginning at about the 25th week of gestation. An anencephalic infant was delivered alive from a breech presentation during the 31st week of gestation. The placenta was markedly circumvallate, with short, thick membranes which did not cover more than 10% of the infant. The course of the pregnancy and the examination of the infant and placenta are discussed, and the pertinent literature is reviewed.
本文报道了一例罕见的膜外妊娠病例。该病例与妊娠约25周开始出现的羊水间歇性流失和血性分泌物有关。在妊娠第31周时，一名无脑儿经臀位分娩存活。胎盘明显呈环状，胎膜短而厚，覆盖婴儿的面积不超过10%。文中讨论了该妊娠过程以及对婴儿和胎盘的检查，并对相关文献进行了综述。
