A health care provider may first spot this condition in your baby during an ultrasound in pregnancy. In many cases, hydrocephalus doesn't develop until the third trimester of the pregnancy. Ultrasounds done earlier in pregnancy may not show this condition.
Your child may be diagnosed with this condition after birth. Your child’s health care provider will examine your child and ask you about their prenatal, birth and family history. If your baby is older, your child’s provider may ask if they care meeting milestones. Children with this condition may be likely to have developmental delays. If your child has a delay, their health care provider may check for underlying problems.
Your baby’s head may be larger than normal. Your child’s health care provider will measure their head. This measurement is called the head circumference. If your baby’s head size isn’t in the normal range or is growing faster than normal, they will have tests. These tests can confirm hydrocephalus.
This test uses sound waves to create an image of the inside of the body. During pregnancy, this test can show the size of the ventricles inside of your baby’s head. It can also be used after birth while the anterior fontanelle remains open.
This test uses large magnets, radio waves and a computer. Together, these show detailed images of organs and structures inside your baby’s body.
This test uses X-rays and computer technology to make detailed images of any part of your baby’s body. These include bones, muscles, fat and organs. CT scans are more detailed than X-rays.
