What is a chorioangioma?
Chorioangioma is a benign vascular malformation of the placenta and represents the most common primary tumour of the placenta. Presence of this vascular malformation can result in significant maternal and fetal morbidity depending on the size of the lesion.
What causes a chorioangioma?
The cause of chorioangioma is unknown. The abnormal masses form in the chorionic tissue, the tissue on the fetal side of the placenta. Chorioangiomas occur in an estimated 1% of pregnancies. The tumors are seen more often in pregnancies where the fetus is female and in those involving multiples (twins, triplets, etc.).
What is chorioangioma placenta?
Placental chorioangioma is the most common benign non-trophoblastic tumor of the placenta. It is derived from primitive chorionic mesenchyme and is typically vascular. Placenta chorioangiomas occur in approximately 1% of pregnancies. Most placental chorioangiomas are small and are not clinically important.
How does chorioangioma cause Polyhydramnios?
The large surface area of the enlarged vessels of the angioma may also predispose to the increased transudation. Polyhydramnios also can be explained by the partial placental insufficiency caused by shunting of the fetal blood into the vessels of the chorioangioma.
How is chorioangioma treated?
The combined use of bipolar cautery with a diode laser proved to be an effective treatment option for symptomatic chorioangioma. With bipolar cautery, surgeons were able to reduce the blood flow to the chorioangioma by coagulating the main feeding vessel, which was too large to be safely coagulated by the laser diode.
Are chorioangiomas benign?
Placental chorioangiomas are benign vascular tumours and are the most common placental tumours, with a prevalence of 1%. Large placental chorioangiomas are rare and may lead to pregnancy complications and poor perinatal outcomes.
What is PMD pregnancy?
Placental mesenchymal dysplasia (PMD) is a rare, benign placental, vascular anomaly. PMD is characterized by placentomegaly and grape-like vesicles resembling molar pregnancy on ultrasonography (USG).
What is Placentomegaly?
Background. Placentomegaly is an important ultrasound finding in pregnancy. It has been associated with normal fetal outcome, polyhydramnios, fetal hydrops, diabetes, partial mole and even fetal growth restriction as in placental mesenchymal dysplasia (PMD).
Do chorioangiomas grow?
“Since my chorioangioma potentially could grow bigger during my pregnancy, my OB/GYN referred me to a maternal fetal medicine specialist who focuses on high-risk pregnancies,” Lauren said. “Two weeks later when I came in for my ultrasound, the chorioangioma looked slightly larger than it did at 20 weeks.
What is battledore in pregnancy?
Battledore placenta is a placenta in which the. umbilical cord is attached at the placental margin; so. called because of the fancied resemblance to the. racquet used in badminton.
How do you treat chorioangioma?
What are placenta Lakes?
Placental lakes are enlarged spaces in the placenta filled with maternal blood. These spaces are also called intervillous spaces because they are found between the placental villi the finger-like projections of the placenta that contain fetal blood vessels .
What is Battledore cord insertion?
In Battledore placenta, the umbilical cord is attached to the placental margin (1) also known as marginal insertion of umbilical cord.

What is a Venus Lake?
Venous lakes are dilated ‘lake-like’ venules in the upper dermis typically seen on the lips or ears of elderly patients. These lesions are dark-blue to purple, soft, raised nodules, usually 2 to 10 mm in diameter.
