摘要

我们描述了一位通过体外受精(IVF)和胚胎移植(ET)受孕的女性。经阴道超声显示，从胚胎移植后1个月到分娩，双胎的大小至少有1周的差异。讨论了囊大小、冠臀长度和妊娠生长的差异，以及妊娠早期超声的含义。

Evidence that difference in size of fraternal twins may originate during early gestation: a case report.

We describe a woman who conceived by in vitro fertilization (IVF) and embryo transfer (ET). Transvaginal ultrasound demonstrated at least 1 week's difference in size of twin gestations from 1 month post-transfer of embryos to delivery. Differences in sac size, crown-rump length, and gestational growth are discussed, as are implications of ultrasound in early pregnancy.
