胎盘间质发育不良（PMD）的特征是多个低回声囊泡，其类似于胎盘中的摩尔变化;然而，妊娠期间PMD的这种形态学变化的过程尚未完全了解。我们对所有以英文发表的PMD病例进行了回顾，并确定了49篇文章，包括110例病例。关于多囊型的胎龄，大约70%的病例在妊娠13-20周时被诊断出来。PMD的另一个特征是胎儿绒毛膜血管的静脉曲张扩张。90%以上的病例在孕晚期被诊断为胎盘伴绒毛膜血管扩张。我们还报告了一个PMD的情况下，发现在妊娠10周根据超声磨牙模式。使用超声和磁共振成像对胎盘进行的系列观察显示，多囊性病变在23周后变得更小。相反，胎儿侧胎盘血管扩张在38周时变得明显。目前的审查强调，胎盘水泡性病变PMD可能先于扩张的胎儿绒毛膜血管在怀孕期间。它还表明了一个潜在的逐步减少的大小PMD的胎盘泡状病变的胎盘图像的系列研究。
Placental mesenchymal dysplasia (PMD) is characterized by multiple hypoechoic vesicles which are similar to molar changes in the placenta; however, the process of such morphological changes of PMD during pregnancy has not been fully understood. We performed a review of all PMD cases published in English and identified 49 articles including 110 cases. With regard to the gestational age at which the multicystic pattern was seen, approximately 70% of cases were diagnosed at 13-20 weeks of gestation. Another characteristic feature of PMD is varicose dilation of fetal chorionic vessels. As many as 90% of cases were diagnosed as placenta with dilated fetal chorionic vessels in the third trimester. We also report a case of PMD which was found at 10 weeks of gestation according to ultrasonic molar patterns. Serial observations of the placenta using ultrasound and magnetic resonance imaging revealed that multicystic lesions became smaller after 23 weeks. In contrast, dilated placental vessels on the fetal side became apparent at 38 weeks. The present review highlights that placental vesicular lesions of PMD may precede dilation of fetal chorionic vessels during pregnancy. It also indicates the potential of a gradual reduction in size of PMD's placental vesicular lesions by serial study of placental images.
