Quick Answer: What Could Be The Cause Of Ventriculomegaly?

How common is Ventriculomegaly?

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

Is Mild Ventriculomegaly normal?

The chance that mild ventriculomegaly represents a normal variant decreases with increasing degrees of dilation. Mild ventriculomegaly is likely to represent a normal variant if no other structural abnormalities are noted and if aneuploidy screening or diagnostic genetic testing results are normal.

How can Ventriculomegaly affect my child?

Babies with mild ventriculomegaly usually will have normal learning and development. However, there is a higher chance for learning problems, ranging from minor delays in development to severe intellectual disabilities. Problems with brain development are more likely when the ventricles measure more than 12 mm.

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.

What does it mean if an unborn baby has fluid on the brain?

Hydrocephalus present from birth Congenital hydrocephalus is when a baby is born with excess fluid in their brain. It can be caused by a condition such as spina bifida, or an infection the mother develops during pregnancy, such as mumps or rubella (German measles).

How is Ventriculomegaly 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 hereditary?

Is ventriculomegaly inherited? Ventriculomegaly usually occurs spontaneously, which means that a child does not inherit the condition from the parents. However, benign macrocephaly tends to run in families and there are some rare inherited causes of hydrocephalus.

What is severe Ventriculomegaly?

Severe ventriculomegaly. This is when the ventricles are larger than 15 mm. (About the size of a hazelnut or larger.)

How long can a person with hydrocephalus live?

The mortality rate for hydrocephalus and associated therapy ranges from 0 to 3%. This rate is highly dependent on the duration of follow-up care. The shunt event-free survival is approximately 70% at 12 months and is nearly half that at 10 years, post-operatively.

Can 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.

What causes enlarged ventricles in the brain?

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.

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.

Is there fluid in the brain?

Cerebrospinal fluid is produced by tissues lining the ventricles of the brain. It flows through the ventricles by way of interconnecting channels. The fluid eventually flows into spaces around the brain and spinal column.

How is hydrocephalus diagnosed?

Diagnosis of Hydrocephalus A diagnosis is made by using brain imaging techniques such as ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and a thorough neurological evaluation during a doctor visit. More tests are often performed in adults in order to diagnose the condition.

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.

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 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.

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 best treatment for hydrocephalus?

The most common treatment for hydrocephalus is the surgical insertion of a drainage system, called a shunt. It consists of a long, flexible tube with a valve that keeps fluid from the brain flowing in the right direction and at the proper rate. One end of the tubing is usually placed in one of the brain’s ventricles.

Can hydrocephalus be treated with medication?

There is little use for medication in hydrocephalus. In some acquired cases, as with tumors and infections, resolving the underlying condition will resolve the hydrocephalus, but most patients still require surgical intervention.
