虽然先天性中胚层肾瘤（CMN）是一种罕见的良性先天性肾肿瘤，但它是新生儿期最常见的实体肾肿瘤。先天性中胚层肾瘤最常见的表现是羊水过多，此前仅报道过 1 例产前胎儿水肿的病例。此前，CMN 的产前诊断是根据妊娠晚期的超声检查结果进行的，最近也有基于磁共振成像 (MRI) 的诊断的报道。在此，我们报告一例产前诊断为经典型 CMN 的病例，根据超声检查和磁共振成像的结果，在妊娠 22 + 3 周时诊断出这一病例。该病例的特征性影像学表现是胎儿水肿和羊水过多。据我们所知，这是报道的最年轻的CMN产前诊断孕龄，也是产前检测到的第二例与胎儿水肿相关的CMN病例。版权所有 (C) 2003 John Wiley Sons, Ltd.
Although congenital mesoblastic nephroma (CMN) is a rare benign congenital renal tumor, it is the most common solid renal tumor in the newborn period. The most common presentation of congenital mesoblastic nephroma is polyhydramnios, and only one case with prenatal fetal hydrops has been previously reported. Prenatal diagnosis of CMN has previously been made on the basis of the findings of sonography in the third trimester, and magnetic resonance imaging (MRI)-based diagnosis has been reported recently. Here we report a case of prenatally diagnosed classical type CMN diagnosed at 22 + 3 weeks of gestation based on the findings of sonography and magnetic resonance imaging. The characteristic imaging findings in this case were fetal hydrops and polyhydramnios. To our knowledge, this is the youngest reported gestational age for prenatal diagnosis of CMN and it is the second case of CMN associated with fetal hydrops detected prenatally.
