Ultrasound findings in molar pregnancy can vary from the classical image of a “snowstorm” pattern seen when using older ultrasound technology, to the complex mass of swollen hydropic trophoblastic tissue as seen here with higher-resolution equipment.

Molar pregnancy is characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta. There are two types of molar: Complete and partial molar pregnancy.

The diagnosis of molar pregnancy involves a combination of ultrasonography and serum ß-hCG level assessments. Therefore, if a patient experiences vaginal bleeding in the first trimester, prompt consultation with her physician is crucial.

2017年6月4日 · Ultrasonic descriptions of early histologically confirmed molar pregnancies include: an empty gestational sac or intrauterine anechoic fluid collection, fluid collection in association with an echogenic mass, thickened endometrium and echogenic fluid-filled levels within the endometrium [15, 16].

2023年1月17日 · In a complete molar pregnancy, the following ultrasound findings may be visible: Enlarged or bulky uterus; Mass with cystic structures; Snowstorm or bunch of grapes appearance; 50% may be diagnosed in the first trimester; It may appear like a normal IUP; It may appear like an empty gestational sac; Large cysts may be seen in the ovaries—theca ...

Pelvic ultrasound scans are a good way of diagnosing a complete molar pregnancy. But they are not as good at picking up partial molar pregnancies. Partial molar pregnancies are still likely to be picked up by other routine tests, such as blood tests.

2024年2月12日 · A molar pregnancy can usually be detected on an ultrasound around 9-12 weeks of pregnancy. However, in some cases, it may be detected earlier if there are signs or symptoms indicating a molar pregnancy.

You should be referred to an early pregnancy assessment unit for a transvaginal (internal) ultrasound scan. Molar pregnancy may show up on an ultrasound scan but sometimes the scan only shows what looks like a miscarriage or an empty pregnancy sac. Molar pregnancy can be difficult to diagnose.

In 63 pregnancies ultrasound examination suggested HM, and in 53 (84%) of these the diagnosis of molar pregnancy was correct, demonstrating relatively high specificity for the ultrasound findings but also highlighting that non-molar hydropic miscarriage may occasionally mimic HM sonographically.

2022年11月12日 · A health care provider who suspects a molar pregnancy is likely to order blood tests and an ultrasound. During early pregnancy, a sonogram might involve a wandlike device placed in the vagina. As early as eight or nine weeks of pregnancy, an ultrasound of a complete molar pregnancy might show:
