We experienced a case with fetal hydrops, polyhydramnios, and a well-defined oval anechoic lesion of approximately 9 cm in size, without blood flow at 26 weeks' gestation. As increased middle cerebral artery peak systolic velocity, the fetal hydrops was caused by a placental tumor such as a chorioangioma; however, the tumor was atypical. Fetal blood hemoglobin was 8.3 g/dl on percutaneous umbilical cord blood sampling. After erythrocytes transfusion to the fetus, the mother normally delivered at 38 weeks' gestation. The placental tumor was histologically diagnosed as a necrotic chorioangioma. Obstetricians should note such atypical chorioangiomas when differential diagnosis of placental tumors.
我们遇到一例妊娠26周时出现胎儿水肿、羊水过多及一个大小约9 cm边界清晰的椭圆形无回声病变且无血流信号的病例。由于大脑中动脉收缩期峰值流速增加，胎儿水肿是由诸如绒毛膜血管瘤等胎盘肿瘤引起的；然而，该肿瘤并不典型。经皮脐血采样时胎儿血红蛋白为8.3 g/dl。给胎儿输注红细胞后，母亲于妊娠38周正常分娩。胎盘肿瘤经组织学诊断为坏死性绒毛膜血管瘤。产科医生在对胎盘肿瘤进行鉴别诊断时应注意此类不典型的绒毛膜血管瘤。
