A molar pregnancy can usually be diagnosed by high resolution ultrasound scans, because of the distinctive appearance of molar tissue. A complete molar pregnancy may be easier to detect by ultrasound than a partial molar pregnancy.
Can you see a molar pregnancy on an ultrasound?
A molar pregnancy can usually be diagnosed by abdominal ultrasound, which can show the presence of cysts in the uterus. A complete mole pregnancy may be easier to detect by ultrasound than a partial mole pregnancy. A woman will also be given a blood test to measure her levels of hCG.
How do you rule out a molar pregnancy?
If your doctor suspects a molar pregnancy, he or she will order blood tests, including one to measure the level of human chorionic gonadotropin (HCG) — a pregnancy hormone — in your blood. He or she will also recommend an ultrasound.
What does a molar pregnancy look like on ultrasound?
The presence of the molar tissue is then detected. Ultrasound scanning shows a honeycomb pattern produced by the numerous vesicles. As they enlarge the image is described to look like a snowstorm, which is due to swollen cysts with bleeding into the uterus. The ovaries are often seen to contain large cysts.
How do you know if you have a partial molar pregnancy?
The most prominent symptom of a molar pregnancy is heavy bleeding from the vagina early in the pregnancy. The blood may be dark brown. Symptoms of a partial molar pregnancy include severe nausea, vomiting, and hypertension (high blood pressure) early in the pregnancy, often in the first trimester.
How long can a molar pregnancy go undetected?
There are often no symptoms of a molar pregnancy. It may only be diagnosed during a routine ultrasound scan at 8-14 weeks or during tests are done after a miscarriage.
Will a molar pregnancy have a heartbeat?
Diagnosis. Most molar pregnancies are diagnosed in the first trimester. This condition may be discovered when a heartbeat does not become detectable by 12 weeks, but this can also be true of missed miscarriages.
What happens if a molar pregnancy is not treated?
If not treated, a molar pregnancy can be dangerous to the woman. It sometimes can cause a rare form of cancer. A molar pregnancy is a kind of gestational trophoblastic disease (also called GTD). This is a group of conditions that cause tumors to grow in the uterus.
Will a molar pregnancy test positive?
Symptoms and diagnosis
Women with a molar pregnancy will have a positive pregnancy test and the same early symptoms of a normal pregnancy. In the absence of medical intervention or diagnosis, the pregnancy might seem normal for the first three to four months.
Who is at risk for a molar pregnancy?
The risk of complete molar pregnancy is highest in women over age 35 and younger than 20. The risk is even higher for women over age 45. Age is less likely to be a factor for partial moles. For choriocarcinoma, risk is lower before age 25, and then increases with age until menopause.
How high are hCG levels in molar pregnancy?
The measurement of high hCG levels in excess of 100,000 mIU/mL suggests the diagnosis of a complete molar pregnancy, particularly when associated with vaginal bleeding, uterine enlargement and abnormal ultrasound findings.
Is a molar pregnancy a real baby?
Complete molar pregnancies have only placental parts (there is no baby) and form when the sperm fertilizes an empty egg. Because the egg is empty, no baby is formed. The placenta grows and produces the pregnancy hormone, hCG. Unfortunately, an ultrasound will show that there is no fetus, only a placenta.
What happens after a molar pregnancy?
A molar pregnancy will not be able to survive. It may end on its own, with a miscarriage. If this does not happen, it’s usually treated with a procedure to remove the pregnancy. You’ll usually be given a general anaesthetic before the procedure, so you’ll be asleep.
How rare is a partial molar pregnancy?
Partial molar pregnancy with a live fetus is a very rare condition, occurring in 0.005 to 0.01% of all pregnancies; it presents a challenging diagnosis, especially when clinical signs are almost completely absent.
Is a partial molar pregnancy twins?
A foetus with a partial mole may survive when it occurs in a dizygotic twin, with one foetus and the other oocyte giving rise to a partial diploid mole, however, a monozygotic twin with triploidy gives rise to a partial mole with an abnormal foetus (16).
What is the reason for molar pregnancy?
What causes a molar pregnancy? Molar pregnancies result when specific genetic errors occur during the fertilization of an egg by a sperm. In a healthy pregnancy, a placenta forms to nourish the growing embryo. With a molar pregnancy, instead of a placenta, a tumor forms inside the uterus.
