Ultrasound Shows Fluid Around Brain

Jane Foley's picture


Dear Midwife,
I had a nuchal translucency test performed at 12 weeks 5 days. Everything else seemed to measure fine except when the sonographer called in the doctor to look over the test results. She said that there seemed to be fluid around the brain.

The doctor said that its possibly nothing or that it could be severe, either way he said it was way to early to tell so I have to go back in 3 weeks for another ultrasound to check it out. I am extremely concerned and have no idea what this means. also i had not had my blood tests done with this test.

What could this mean?? Could it be nothing?


It is always scary when there is a finding about the baby's brain on an ultrasound. Since you are so early, it can be normal to see a little fluid in the developing brain. Most of the time when you return for the follow up ultrasound, all is well.

The follow up ultrasound is very important. If there is worsening fluid on the brain, or what is called hydrocephalus, a search will follow into the cause and if there are any associated abnormalities. The collective data will then determine the prognosis.

If you have any questions after the follow up ultrasound, let me know and we can talk in more detail.
