What causes snowstorm appearance of molar pregnancy?
Ultrasound is the standard imaging modality for identifying molar pregnancy. Classically, a ‘snowstorm pattern’ has been described, resulting from the presence of a complex vesicular intrauterine mass containing many ‘grape-like’ cysts.
What is complete hydatidiform mole?
Overview. A molar pregnancy — also known as hydatidiform mole — is a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta. There are two types of molar pregnancy, complete molar pregnancy and partial molar pregnancy.
What is the difference between a complete and incomplete hydatidiform mole?
In complete hydatidiform mole, there is no fetal tissue present; in partial hydatiform moles, there is some residual fetal tissue. Both are due to the over-proliferation of chorionic villi.
What are the risk factors to molar pregnancy?
Risk factors for molar pregnancy maternal age of less than 20 or more than 40 years. race – Asian women are at increased risk. dietary deficiencies including lack of folate, beta-carotene or protein. prior history of gestational trophoblastic disease – the recurrence rate is one in 100.
Why is there vaginal bleeding in hydatidiform mole?
Molar tissue separates from the decidua, causing bleeding. The uterus may become distended by large amounts of blood, and dark fluid may leak into the vagina. This symptom occurs in 50% of cases. Patients may also report severe nausea and vomiting.
Is there a heartbeat in molar pregnancy?
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.
Do molar pregnancies run in families?
Recurrent molar pregnancy may even be familial, but this is an exceedingly rare condition (2). It is proposed that patients with recurrent hydatidiform moles fall into two groups.

Is a historic snowstorm in store for Boston this weekend?
Meteorologists say a potentially-historic snowstorm is in store for Boston this weekend, when a nor’easter barrels into southern New England on Saturday.
What is snowstorm sign in obstetric imaging?
Snowstorm sign in obstetric imaging is classically seen in complete hydatiform mole. It is characterized by the presence of many hydropic villi which gives the ultrasonographic appearance of a central heterogeneous mass having a solid, hyperechoic area and interspersed with a multitude of cystic areas and filling the entire uterine cavity.
