Co-existent molar pregnancy of about 21 weeks.

This video shows Co-existent molar pregnancy of about 21 weeks.
Molar pregnancy with coexisting fetus carries a significant risk to both mother and the fetus. Maternal risks include abnormal bleeding, pre-eclampsia, eclampsia, hyperthyroidism, anemia, persistent gestational trophoblastic disease, preterm delivery, and abruption.
Hydatidiform mole is a common complication of pregnancy. It consists of a nonviable embryo that implants and proliferates within the uterus.
A hydatidiform mole can either be complete or partial. The presence or absence of a fetus or embryo is used to distinguish the complete from partial moles:
Complete moles are associated with the absence of a fetus
Partial moles usually occur with an abnormal fetus or may even be associated with fetal demise.

The absence or presence of a fetus or embryo is used to distinguish the complete from partial moles: complete moles are associated with the absence of a fetus. partial moles usually occur with an abnormal fetus or may even be associated with fetal demise.
Rarely, moles co-exist with a normal pregnancy (co-existent molar pregnancy), in which a normal fetus and placenta are seen separate from the molar gestation.
A hydatidiform mole is a growth of an abnormally fertilized egg or an overgrowth of tissue from the placenta. Women appear to be pregnant, but the uterus enlarges much more rapidly than in a normal pregnancy. Most women have severe nausea and vomiting, vaginal bleeding, and very high blood pressure.
On Ultrasound it looks like a bunch of vesical with interspersed fluid seen in the whole of the uterine cavity
Mostly painless vaginal bleeding during the second trimester of pregnancy is seen. They are diagnosed by ultrasound imaging. Extremely high levels of human chorionic gonadotropin (HCG) are suggestive, but not diagnostic, of molar pregnancy.
A molar pregnancy is when there's a problem with a fertilized egg, which means a baby and a placenta do not develop the way they should after conception. A molar pregnancy will not be able to survive. It happens by chance and is very rare.
A hydatidiform mole is a pregnancy in which the placenta contains grapelike vesicles (tiny sacs) which are visible to the naked eye. The vesicles arise by distention of the chorionic villi by fluid. When examined under the microscope, hyperplasia of the trophoblastic tissue is noted.
Hydatidiform mole: It is a tumor that forms in the uterus as a mass of cysts resembling a bunch of grapes. Hydatidiform moles appear during the childbearing years, and they do not spread outside the uterus. A malignancy called choriocarcinoma may start from a hydatidiform mole.
A pelvic ultrasound scan will show the presence of tissue inside the uterus, with the characteristic snowstorm appearance of a molar pregnancy. The scan may be performed via the abdominal scan or the vagina.
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.
Mostly, a hydatidiform mole is an abnormally fertilized egg that develops into a hydatidiform mole rather than a fetus (a condition called molar pregnancy). Hydatidiform moles are most common among women under 17 or over 35. In the United States, they occur in about 1 in 2,000 pregnancies.
Who is at risk for 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. But age is less likely to be a factor for partial moles. For choriocarcinoma, the risk is lower before age 25 and then increases with age until menopause.
Hydatidiform moles should be taken as premalignant lesions because 15-20% of complete hydatidiform moles (CHMs) and 1% of partial hydatidiform moles (PHMs) undergo malignant transformation into invasive moles, choriocarcinoma, or, in rare cases, placental-site trophoblastic tumors.
On ultrasound, complete molar pregnancy can be detected as early as eight or nine weeks of pregnancy, but it may show: No embryo or fetus.
Diagnosis. Mostly, doctors can diagnose a hydatidiform mole shortly after it forms. Hydatidiform mole can be suspected on the basis of symptoms, such as a uterus that is much larger than expected and a vaginal discharge of grapelike tissue. A pregnancy test is done.
Complete molar pregnancies have only placental parts (there is no baby) and form when the sperm fertilizes an empty egg. Because if the egg is empty, no baby is formed. The placenta grows and produces the pregnancy hormone, hCG. Unfortunately, an ultrasound will show no fetus, only a placenta.
A molar pregnancy can have serious complications — including a rare form of cancer — and requires early treatment.
