The reality is that if the brain is not maintained in some form of a liquid phase, it will become altered and twisted beneath its bodily mass, and sensitive tissue cells will begin to rip and be harmed. The barrier of Cerebrospinal fluid CSF that covers the brain also acts as a barrier against potential hazards connected with mechanical stress or any other type of applied force, such as if a person falls. Another example would be, if a person falls and harms their head severely, or if they are beaten and a blunt force is applied to the head.
Regardless of pressure fluctuations within the ventricles, the rate of Cerebrospinal fluid CSF production in the ventricles stays constant. If the flow of Cerebrospinal fluid CSF is impeded at any point or site in the ventricular system, it might be a problem. Cerebrospinal Fluid CSF will continue to be available and produced, but it will be unable to leave the platform.
As a result, the stress inside the ventricles would rise, and the increasing pressure may effectively cause the ventricles to enlarge. The expanding ventricles may then clash with other brain regions, leading to a variety of health complications based on where the blockage occurred and which structures or tissues are most influenced by this expansion.
When this occurs in children whose skulls have not fully ossified typically under the age of 2 , the head may enlarge. When CSF is produced in the lateral ventricle, it fills the cavity before passing through the interventricular foramen of Monro and entering the third ventricle.
Cerebrospinal fluid CSF produced in the third ventricle departs the area via the Sylvius cerebral aqueduct and enters the fourth ventricle in addition to CSF produced in the lateral ventricle.
The cerebral ventricular system is made up of these chambers and their interconnected passages. A CT scan can be used to determine the volume of the lateral ventricles and other structures within the brain. Physicians can use the scan to determine not just the length of the ventricles, but also the density of the cerebrospinal fluid CSF they hold. This data can be utilized to prevent and manage brain disorders such as hydrocephalus, which is an excessive accumulation of fluid in the ventricle.
Ventriculomegaly is a disorder that causes the lateral ventricle to develop improperly. The explanation of ventriculomegaly is uncertain, but it is extremely debated that atrophy of structural components present around the lateral ventricles, as well as a decrease in the amount of the nearby periventricular structures, may be major factors responsible, allowing the ventricles to broaden and fill in the region. One possibility is a stoppage of venous blood or Cerebrospinal fluid CSF circulation which leads to an increase in the volume of cerebrospinal fluid CSF in the ventricles.
A further explanation is that mechanical pressure and shear pressures cause injury and atrophy of surrounding structures that encircle the ventricles. A few of the hypothesized reasons for deformation and shear stresses include venous blood and Cerebrospinal fluid CSF flow obstruction, venous back pressure, anomalous pressure waves, and pounding-type waves known as water hammers. Tumours of the lateral and third ventricles constitute a special problem to neurosurgeons due to their deep placement and proximity to critical neuronal and circulatory systems.
However, only 7 per cent of occurrences are in the older population. In adults, nearly half of all intraventricular mass lesions are situated in the lateral ventricle, however, in kids, the ratio is significantly smaller. Intraventricular mass lesions are caused by a wide range of benign and malignant malignancies. In the elder age group, the most common lateral ventricle tumours comprise astrocytoma, meningioma, glioblastoma, ependymoma, and choroid plexus papilloma.
In comparison, the most common lateral ventricle cancers in children include subependymal giant cell astrocytoma, ependymal, choroid plexus papilloma, choroid plexus carcinoma and astrocytoma.
Although numerous surgical methods can be used to access intraventricular lesions, surgical excision remains the primary treatment method for lateral and third ventricular malignancies. While transcortical or transcallosal methods can yield in full tumour excision, they are linked with an elevated risk of brain parenchymal damage. A hydrocephalus-causing blockage can be caused by several reasons, including a tumour, infection, or congenital abnormalities.
