What are ventricles and what do they indicate in the brain?
The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).
What does an enlarged ventricle in 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.
Why are ventricles in the brain important?
You have four brain ventricles—cavities within the brain that produce and store cerebrospinal fluid (CSF). This liquid surrounds your brain and spinal cord, cushioning them and protecting them from trauma. It is also responsible for removing waste and delivering nutrients to your brain.
How is an enlarged brain ventricle treated?
The treatment in these cases is a shunt operation. A shunt is a thin tube that is implanted in the brain by a neurosurgeon. It is inserted into the ventricles to drain excess CSF away from the brain.
What can cause enlarged ventricles?
Two of the main factors that cause enlarged ventricles are:
- An injury or problem with brain development around the ventricles.
- A blockage or imbalance in the ventricular system which prevents spinal fluid from moving or being absorbed normally.
What do the ventricles do?
ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system. Ventricles occur among some invertebrates.
Is dilated brain ventricles treatable?
How is Ventriculomegaly Treated? Mildly enlarged ventricles often need no treatment. Hydrocephalus can be treated soon after birth with a procedure that creates a pathway for extra fluid to drain out of the brain.
Should I worry about mild ventriculomegaly?
Confirmation that mild ventriculomegaly is isolated increases the likelihood that long-term neurodevelopment will be normal, and identification of other CNS malformations makes it more likely that the fetus will have neurologic abnormalities, including developmental delay.
Does NPH cause tiredness?
Some people with NPH experience a rolling gait, often when tired or stressed. If you experience this all the time, go to your GP, as your shunt may need adjusting.
Can ventriculomegaly be misdiagnosed?
Some structural central nervous system (CNS) anomalies, such as holoprosencephaly, hydranencephaly, porencephaly, or schizencephaly, and cystic lesions, such as arachnoid cysts, result in abnormal fluid collections in the fetal brain that may be misdiagnosed as ventriculomegaly, although these anomalies do not truly …
Does ventriculomegaly resolve?
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.
