Question: Is Mild Ventriculomegaly Normal?

What is severe Ventriculomegaly?

Severe ventriculomegaly.

This is when the ventricles are larger than 15 mm.

(About the size of a hazelnut or larger.).

What do enlarged ventricles in the brain mean?

Hydrocephalus is the abnormal enlargement of the brain cavities (ventricles) caused by a build-up of cerebrospinal fluid (CSF). Hydrocephalus can be caused by problems with CSF secretion, CSF flow or CSF absorption.

What is the life expectancy of someone with hydrocephalus?

What is the life expectancy of a child who has hydrocephalus? Children often have a full life span if hydrocephalus is caught early and treated. Infants who undergo surgical treatment to reduce the excess fluid in the brain and survive to age 1 will not have a shortened life expectancy due to hydrocephalus.

What could be the cause of Ventriculomegaly?

Ventriculomegaly is a condition in which the ventricles appear larger than normal on a prenatal ultrasound. This can occur when CSF becomes trapped in the spaces, causing them to grow larger. Ventricles develop early in pregnancy and can be seen on a prenatal ultrasound in the second trimester, at about the 15th week.

Can mild Ventriculomegaly go away?

If your child has mildly enlarged brain ventricles or ventriculomegaly without other complications, the condition may resolve on its own. When hydrocephalus is more severe or progresses, timely treatment is important.

Can enlarged brain ventricles be normal?

The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.

How common is Ventriculomegaly?

The incidence of isolated fetal ventriculomegaly is 0.5 to 1.5 per 1000 pregnancies.

Can Ventriculomegaly be treated?

How is ventriculomegaly treated? Treatment is usually only required if a baby shows signs of developing hydrocephalus. The aim of treatment is to reduce the pressure on the brain by draining away the CSF. In most cases, the fluid is drained away using a ‘shunt’, which is a long tube made of silicone.

Is Ventriculomegaly a disability?

Ventriculomegaly associated with abnormal findings and other structural malformations, often has an adverse prognosis, which ranges from disability (often mild) to death. However, in cases of mild isolated ventriculomegaly, there is around a 90% chance of a normal outcome.

What is the normal size of brain ventricles in fetus?

In a normal fetal brain, the ventricles are less than 10 mm wide. When the ventricles are between 10-mm and 15-mm wide, the baby is diagnosed with mild ventriculomegaly. If the ventricles are more than 15 mm wide, the enlargement is considered severe.

What is the difference between hydrocephalus and Ventriculomegaly?

Ventriculomegaly is the term for enlarged brain ventricles, while hydrocephalus is the combination of ventriculomegaly and pressure on the brain.

How common is mild Ventriculomegaly?

About 1 in every 500 babies will have mild ventriculomegaly. In most cases, babies with this ultrasound finding are born healthy.

Can hydrocephalus go away on its own?

It does not go away on its own and needs special treatment. Hydrocephalus is due to the accumulation of cerebrospinal fluid (CSF) in the cavities deep within the brain.

Can enlarged ventricles cause headaches?

Hydrocephalus that develops in children or adults (acquired hydrocephalus) can cause headaches. The headache may be worse when you wake up in the morning. This is because the fluid in your brain does not drain as well while you’re lying down and may have built up overnight.

How is Ventriculomegaly measured?

Antenatal ultrasound The measurement should be in the true axial plane at the atria of the lateral ventricle and glomus of the choroid plexus. The ventricle is measured from inner margin of the medial ventricular wall to inner margin of the lateral wall.

Is Ventriculomegaly a neural tube defect?

Sometimes ventriculomegaly is associated with developmental problems of the fetal spine called neural tube defects or spina bifida. Infants with ventriculomegaly may also have chromosome abnormalities or genetic syndromes.

What does it mean when a fetus has fluid on the brain?

Hydrocephalus, or “water on the brain,” is a condition associated with a buildup of cerebrospinal fluid (CSF) in or around the brain. If left untreated, this can lead to brain tissue stretching, significantly affecting your child’s growth and development.

What causes fluid in fetus brain?

The baby is born with a blockage in the cerebral aqueduct, a long passage in the midbrain that connects two large ventricles. This is the most common cause. The choroid plexus produces too much CSF. Health conditions in the developing baby can cause problems in how the brain develops.

What is borderline Ventriculomegaly?

5 Borderline ventriculomegaly is defined as an atrial width of 10–15 mm at 15−40 weeks of gestation. Although fetal cerebral ventriculomegaly can be diagnosed relatively easily and accurately using ultrasonography, determi- nation of fetal outcomes is more complicated, and this affects the counseling of mothers.

What is the normal size of lateral ventricles?

Previously established cut-off values of fetal cerebral lateral ventricles (FCLVs) dimensions are: normal (< 10 mm), mild/borderline VM (10–12 mm), moderate VM (13–15 mm), and severe VM (> 15 mm).
