Two female fetuses with generalized edema were karyotyped as 45,x. However, a cystic hygroma can also be an indicator of other In 10% of cases the fetal karyotype is normal, there are no other obvious defects and the hygromas resolve during pregnancy.
Ultrasound image of a septated cystic hygroma which
The unfavorable outcome is 77.8%.
In these cases the prognosis is good.
However, there are also patients with cystic hygroma with resolution or survive at birth without other malformations (16.7—22.2%) [9,11].

Cystic hygromas are single or multiple cysts found mostly in the neck region.
The rate of abnormal karyotype was found to be 61% and the global rate of unfavorable outcome, independently of.
Cesarean section if there is hydrops or large cystic hygromas preventing flexion of the head. The association of generalized edema with large nuchal cystic hygromas was. The lymphatic system is a network of vessels that maintains fluids in the blood, as well as transports fats and immune system cells. Cystic hygroma refers to the finding of marked skin thickening extending along the entire length of the fetus at early ultrasound examination (benacerraf and frigoletto, 1987;
If the cystic hygroma does not resolve by 20 weeks, the chance of a healthy outcome decreases to two to nine percent.
In these cases the prognosis is good. Intrauterine diagnosis of hydrops by ultrasound may allow successful treatment and reversal in selected cases, but the majority die. What is a cystic hygroma? She passed both an early anatomy and full anatomy scan, as well as an early fetal echo and late second trimester fetal echo.
Further treatment (usually removal of the cystic hygroma) is then offered after birth.
A hemangioma of the skin is an abnormal buildup of blood vessels on or under the surface of the skin. Ultimately, only 15% to 20% of all cases of cystic hygroma identified in the first trimester will result in the birth of a healthy neonate at term ( malone et al., 2005a ). If your baby has normal chromosomes and the cystic hygroma disappears by 20 weeks of pregnancy, the outcome will probably be good. Cystic hygroma is well known with poor outcome because the fetuses usually have chromosomal abnormalities and hydrops fetalis or iufd often occurs during pregnancy.
Sometimes babies are born with a cystic hygroma, visible as a soft lump.
Cystic hygromas are rare, accounting for 6% of all benign lesions of infancy and early childhood.[7]. Additionally, about one in four pregnancies with cystic hygroma in which a fetal abnormality has been excluded will result in spontaneous intrauterine fetal demise. Fetal cystic hygroma is a congenital malformation of the lymphatic system. 50% of these lesions are present since birth, and the remaining 50% appear by the age of 2.[7].
In 80 percent of cases, cystic hygromas appear on the face, including the head.
About 60 percent of cystic hygromas result from chromosomal abnormalities. Genetic burden, fetal malformations, and fetal outcomes of 93 fetuses with cystic. It is almost always detected before the 20 th week of pregnancy. Pregnancy outcome was known for 31 of these cases.
According to the fetal medicine foundation, cystic hygromas affect 1 in 800 pregnancies and 1 in 8,000 live births.

Cystic hygromas found early in pregnancy sometimes go away before birth. In these cases the baby often has a.
They usually occur in the fetal/infantile and pediatric populations with most lesions presenting by the age of two.
