Both a baby’s genes and their environment in the womb can cause problems with the way their lymphatic system grows. This is how cystic hygromas form. It may happen on its own or with genetic conditions such as Turner, Down, or Noonan syndromes.
When adults get a cystic hygroma, it can be due to trauma or a past respiratory infection. But it’s often not clear what caused the cyst. It may even disappear during pregnancy.
Cystic Hygroma Diagnosis:
When you’re pregnant, your doctor may find your baby’s cystic hygroma during a routine ultrasound. These cysts are usually found by the 20th week of pregnancy. You may also notice it after your baby is born or even later in your child’s life.
If you find out while you’re pregnant that your baby has a cystic hygroma, the doctor will probably recommend genetic testing to see if there are other problems. These can include:
• CVS (chorionic villus sampling): The doctor removes some of these wispy pieces of tissue from the placenta that share your baby’s genetic makeup.
• Amniocentesis: The doctor tests a sample of your amniotic fluid to test for genetic conditions.
You’ll also have frequent ultrasounds to watch for changes in the cyst and any complications.
The doctor will likely plan for you to give birth by C-section at 38 weeks. Find a hospital where you have access to both neonatal intensive care and pediatric surgeons. The doctor can help you choose one.
