What are intraventricular tumors?
Intraventricular tumors (also known as ventricular tumors) are generally benign tumors or lesions found within the ventricles of the brain. These tumors may arise from a variety of cells in the region and often obstruct the flow of cerebrospinal fluid and cause a buildup of pressure in the skull.
What is an intraventricular cyst?
Intraventricular simple cysts have appearances similar to arachnoid cysts elsewhere (except for their location). They follow CSF on all modalities and sequences and have a very thin or imperceptible wall. They are most frequently encountered in the trigone of the lateral ventricles 6.
How might a Tumour in the 4th ventricle be removed?
Access to these tumors is typically accomplished via a suboccipital craniotomy/craniectomy followed by a transvermian or telovelar approach.
Is Subependymoma a cancer?
What is Subependymoma? Subependymomas are benign tumors in the ventricles that grow from the ventricular wall into the spinal fluid spaces within the brain. These lesions may obstruct spinal fluid flow and/or put pressure on surrounding structures, causing symptoms including headaches and confusion.
What is an intraventricular meningioma?
Intraventricular meningiomas are rare tumors usually encountered in adults and are somewhat distinct from the far more common extra-ventricular meningioma. On imaging, they classically present as vividly enhancing solid mass at the trigone of the lateral ventricles.
What is colloid cyst?
A colloid cyst is a slow-growing tumor typically found near the center of the brain. If large enough, a colloid cyst obstructs cerebrospinal fluid (CSF) movement, resulting in a build up of CSF in the ventricles of the brain (hydrocephalus) and elevated brain pressure.
Should a colloid cyst be removed?
Because a colloid cyst can obstruct the flow of fluid into the brain’s third ventricle, it requires immediate medical attention. Common symptoms of colloid cysts include memory problems, headaches, loss of consciousness, and confusion. Surgery to remove the colloid cyst generally cures a person with this condition.
Can you live with an arachnoid cyst?
Most arachnoid cysts are stable and do not require treatment. They are four times more common in boys than in girls. Arachnoid cysts are diagnosed with a CT or MRI scan. Treatment, if necessary, involves draining the fluid through surgery or shunting.
What happens if the fourth ventricle is damaged?
The fourth ventricle dilates, causing severe cranial nerve dysfunction and balance problems. While an inflammatory condition is at the root cause of this condition, the secondary closure of the aqueduct can be caused by overdrainage of the spinal fluid by a shunt.
Is astrocytoma a cancer?
Astrocytoma is a type of cancer that can occur in the brain or spinal cord. It begins in cells called astrocytes that support nerve cells. Some astrocytomas grow very slowly and others can be aggressive cancers that grow quickly. Astrocytoma is a type of cancer that can form in the brain or spinal cord.
What is the treatment for Subependymoma?
Subependymomas can be treated with surgery and radiation therapy. In many cases, complete removal with surgery will be curative. When the tumor removal is not complete, radiation treatment can provide a long period of control. Overall, subependymomas have a high survival rate.
What is intraventricular neoplasm?
Intraventricular neoplasms are rare and arise from periventricular structures such as the walls of the ventricular system, the septum pellucidum and the choroid plexus . Many tumor types arise from or can bulge into the ventricular system, although there are certain lesions that are relatively restricted to ventricles.
What are intraventricular masses of the brain?
Intraventricular masses (an approach) The ventricular system of the brain plays host to a variety of unique tumors, as well as tumors that are more frequently seen elsewhere (e.g. meningiomas). Besides, some intra-axial (parenchymal) masses can be mostly exophytic and thus appear mostly intraventricular.
What are the types of neoplasms of the ventricular system?
Many other neoplasms involve the ventricular system, including lymphoma, low- and high-grade gliomas, intraventricular craniopharyngioma, and primitive neuroectodermal tumor ( 92 ). A wide variety of neoplasms involve the ventricular system.
What is the surgical approach to a ventricle tumor?
The surgical approach is dependent on the tumor type, size and location specific to the ventricle. The ventricles of the brain are fluid-filled structures that produce the cerebrospinal fluid that bathes the brain and spinal cord.
