Ultrasound appearance of hydatidiform mole

A woman's pregnancy is a very happy thing, but sometimes a woman will develop a hydatidiform mole after pregnancy. Hydatidiform mole is a relatively harmful female reproductive disease, which has a great impact on women's physical health. In severe cases, the uterus needs to be removed. In fact, if you actively treat it, hydatidiform mole is not a serious disease. So what is the ultrasound manifestation of hydatidiform mole? The following introduces the ultrasound manifestation of hydatidiform mole.

The early symptoms of women pregnant with hydatidiform mole are the same as those of women with normal pregnancy, including amenorrhea and early pregnancy reactions. Only in the later stages of pregnancy will there be some different manifestations, such as vaginal bleeding and abdominal pain, which is already a very dangerous time. Whether it is a hydatidiform mole can be determined through early ultrasound examination, which is different from normal pregnancy.

Hydatidiform mole is not a normal pregnancy. After a woman becomes pregnant, the trophoblastic cells of the placenta grow and form blisters of varying sizes. These blisters are connected together and look like the grapes we usually eat, hence the name. There are many causes of hydatidiform mole, such as nutritional factors, infection factors, endocrine disorders, lack of fertilized eggs and racial factors. In the early stages of pregnancy, women with hydatidiform mole look no different from women with normal pregnancies. At this time, an ultrasound examination can be performed. There are some differences in the early ultrasound manifestations of hydatidiform mole and those of women with normal pregnancies.

1. The gestational sac can be seen through ultrasound examination one month into the pregnancy, but the gestational sac is still very small at this time and there is no fetal bud or fetal heart, so it is impossible to determine whether it is a hydatidiform mole. Screening for hydatidiform mole is best done after 5 weeks of pregnancy.

If a fetal bud is seen during an ultrasound examination at 2 to 5 weeks, then hydatidiform mole can be ruled out. If no fetal bud is seen, hydatidiform mole is suspected. If there are other symptoms at this time, such as particularly strong pregnancy reactions that last particularly long, an unusually large uterus found during examination, and irregular vaginal bleeding after menstruation, then it is very likely to be a hydatidiform mole.

3. We generally recommend that patients undergo another ultrasound examination after 8 weeks of pregnancy. If no embryo bud is seen at this time and no fetal heartbeat is detected during the examination, it is generally confirmed to be a hydatidiform mole. Patients with hydatidiform mole are often accompanied by ovarian cysts, and sometimes have abdominal pain, high blood pressure, proteinuria and hyperthyroidism, which can also be detected in the early stages of pregnancy.

The incidence rate of hydatidiform mole in my country is 0.81%. Any woman in her childbearing period may develop hydatidiform mole, especially women under 20 years old and over 40 years old. If a woman has had a hydatidiform mole once, the probability of developing a hydatidiform mole in the second pregnancy will increase a lot. Hydatidiform mole is not a normal pregnancy and is very dangerous. The pregnancy must be terminated in time to avoid dangerous situations such as heavy bleeding. In addition, going to the hospital for relevant examinations before and in the early stages of pregnancy can rule out whether it is a hydatidiform mole. Early examination and diagnosis and timely treatment can avoid risks.
