图示：葡萄胎葡萄状绒毛。葡萄胎时，子宫随时间而变大，但没有胎儿。HCG明显升高。病人看起来常比同期正常孕妇子宫大，常伴妊娠剧吐。病人可出现阴道流血，可排出部分葡萄状绒毛。
The grape-like villi of a hydatidiform mole are seen here. With molar pregnancy, the uterus is large for dates, but no fetus is present. HCG levels are markedly elevated. Patients with a hydatidiform mole are often large for dates and have hyperemesis gravidarum more frequently. Patients may present with bleeding, and may pass some of the grape-like villi.
