In cystic hygroma, cystic structures appear due to the
accumulation of fluid under the skin in the neck region due to a disorder in
the lymphatic system and obstruction.
Cystic hygroma is likely to be associated with different
chromosome disorders, especially Turner Syndrome (45, X0). Chromosomal anomaly
is found in approximately half of the cases. Therefore, chromosomal examination
of the fetus should be done with amniocentesis or fetal blood sampling. Fetuses
with cystic hygroma are also more likely to have other anomalies.
It is not a problem that can be cured, and death often occurs
in the womb. In large and septal cystic hygromas, the fate of the fetus will be
worse in those accompanying hydrops. Sometimes it is observed that the cystic
hygroma has improved over time. It may also be that the baby lives completely
normal after birth.
Cystic hygroma anoploidy is the most abnormal anomaly.
Approximately 70% of them have chromosomal anomalies. Turner syndrome (45, X0)
is the most common chromosomal anomaly in cystic hygroma. Trisomy 21 is more
common in cystic hygromas detected in the first trimester.
