What is a cyst on the umbilical cord?
Umbilical cord cysts are usually classified as true cysts or pseudocysts. True cysts are derived from the embryological remnants of either the allantois or the omphalomesenteric duct, are located typically towards the fetal insertion of the cord and range from 4 to 60 mm in size 21 - 23.
What is the prevalence of umbilical cord cysts in second and third trimester?

Do first trimester umbilical cord cysts go away?
Most cord cysts detected in the first trimester are transient and disappear by 14 weeks' gestation. These transient cysts are not associated with an additional risk to the pregnancy. Umbilical cord cysts are classified as either true cysts or pseudocysts.
How common are umbilical cord problems?
Nuchal cords are a surprisingly common condition, occurring in as many as 35% of pregnancies. A nuchal cord becomes dangerous when the cord wraps tightly around the baby's neck, often during labor and delivery, and the flow of blood to the baby is interrupted.

Atresia, aplasia, or agenesis of one artery can lead to single umbilical artery syndrome [5]. Single umbilical artery (SUA) is the most common abnormality of the umbilical cord.
What causes umbilical cord abnormalities?
The cord may be too long or too short. It may connect improperly to the placenta or become knotted or compressed. Cord abnormalities can lead to problems during pregnancy or during labor and delivery. In some cases, cord abnormalities are discovered before delivery during an ultrasound.
What causes placental cyst?
Conclusions: Most placental surface cysts are associated with a normal pregnancy outcome. Most such cysts are related to cystic change in an area of subchorionic fibrin. Cysts larger than 4.5 cm or more than 3 in number are more frequently associated with intrauterine growth restriction.

What are the abnormalities associated with short or long umbilical cords?
Complications associated with long or short umbilical cord may explain this enigma. Excessively short cords have been associated with a delay in second stage of labor, irregular fetal heart rate, placental abruption, rupture of umbilical cord, inversion of uterus, birth asphyxia, and cord herniation.

What happens when the umbilical cord is damaged?
When the umbilical cord develops a problem, such as prolapse or cord knots, it can cause complications with the pregnancy and child development.
What is a false cyst?
False cysts may relate to chromosomal anomalies or genetic conditions in the baby. Second- or third-trimester cysts, combined with other abnormalities, may come with an increased risk of miscarriage or structural anomalies. Umbilical cord cysts in the first trimester generally do not affect pregnancy, fetal growth, or birth.
How big is a cyst?
They most often range in size between four and sixty millimeters. Most true cysts abate on their own. False cysts. A false cyst, or pseudocyst, is more common than a true cyst. They can occur anywhere on the umbilical cord. A false cyst contains fluid from Wharton's jelly, or the cushiony substance between blood vessels.
Where do true cysts occur?
True cysts. A true cyst occurs at the placental end of the umbilical cord, close to where it connects to the infant. It contains fluid from the embryo, and is a small remnant of the umbilical vesicle. They most often range in size between four and sixty millimeters. Most true cysts abate on their own.
Can a placental cyst cause fetal growth retardation?
A placental cyst may cause fetal growth retardation if attached close to umbilical cord insertion. A doctor should closely monitor a placental cyst that exists near umbilical cord insertion, to ensure the regular flow of blood through the umbilical cord.
Can a cyst in the umbilical cord be a single cyst?
A patient can have a single cyst or multiple cysts. Doctors diagnose umbilical cord cysts most often in the first trimester, using ultrasound technology. Cysts found in the first trimester generally do not affect pregnancy. Cysts that persist into the second or third trimester, however, have higher odds of causing complications.
How long does it take for umbilical cord cysts to resolve?
All cysts resolved on follow-up sonography, which was performed between 9 weeks 4 days and 20 weeks 5 days. Patients with umbilical cord cysts were found to have a lower body mass index than those with normal umbilical cords. There was no significant difference in abnormal sonographic findings between cohorts.

During the first trimester, the prevalence of umbilical cord cysts ranges from 0.4 to 3.4% 1 - 5. The prevalence of umbilical cord cysts in the second and third trimesters is unknown and, to date, relevant investigations have been confined to case reports or small series 6 - 20. There is a difference in the clinical significance and the prognosis between first-trimester and second/third-trimester umbilical cord cysts. According to most studies, the majority of first-trimester cysts are transient findings that have no adverse effect on pregnancy outcome 1, 2, 4. Yet, the prognosis in cases with persistent cysts seems to be similar to that of second-trimester cysts 3 .
What is the size of a true cyst in the umbilical cord?
