What is an intraventricular mass?
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 are brain ventricles?
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).
How does CSF leave the 4th ventricle?
From the fourth ventricle, the CSF may exit through the foramen of Lushka laterally, or the foramen of Magendie medially to the subarachnoid space. Passing through the foramen of Magendie results in filling of the spinal subarachnoid space.
What is central Neurocytoma?
Central neurocytomas are generally noncancerous (benign) brain tumors in the ventricles, which are the fluid-filled spaces within the brain. These lesions may obstruct spinal fluid flow and/or put pressure on surrounding structures, causing symptoms including headaches and confusion.
How big can brain tumors get?
The large majority of pituitary adenomas are benign and fairly slow-growing. Even malignant pituitary tumors rarely spread to other parts of the body. Adenomas are by far the most common disease affecting the pituitary. They commonly affect people in their 30s or 40s, although they are diagnosed in children, as well.

What is the main function of the ventricles in the brain?
Aside from cerebrospinal fluid, your brain ventricles are hollow. Their sole function is to produce and secrete cerebrospinal fluid to protect and maintain your central nervous system.
How can I increase my CSF flow?
These techniques include massage and manipulation of the spine. Walking, stretching, cycling, heat, and yoga may all help SFF.
Does CSF go to the heart?
The CSF passes from the lateral ventricles to the third ventricle through the interventricular foramen (of Monro). From the third ventricle, the CSF flows through the cerebral aqueduct (of Sylvius) to the fourth ventricle.
Is Neurocytoma a glioma?
Treatment for a central neurocytoma typically involves surgical removal, with an approximate 1 in 5 chance of recurrence. Central neurocytomas are classified as a grade II tumor under the World Health Organization’s classification of tumors of the nervous system….

How rare is a central Neurocytoma?
CN is typically located in the lateral ventricles, near the foramen of Monro, with a characteristic attachment to the septum pellucidum. Central neurocytomas are rare, constituting only 0.25-0.50% of all intracranial tumors. However, they are the most common primary intraventricular tumors in adults.
Is there such a thing as enhancing intraventricular mass?
Although the differential diagnosis for an enhancing intraventricular mass is quite extensive, meningiomas, ependymomas, and choroid plexus neoplasms are some of the more common lesions centered in the atria of the lateral ventricles. Intraventricular meningiomas are relatively uncommon, accounting for 0.5% to 3.7% of all intracranial meningiomas.
Where is an intraventricular cavernoma located on the head?
Intraventricular cavernoma. A non-contrast computed tomography (CT) head exam demonstrated a hyperdense midline intraventricular lesion located along the septum pellucidum, extending into the frontal horns of both lateral ventricles and to the level of the foramen of Monro (Figure 1).
What causes hyperdense lesions on a CT scan?
In contrast to typical astrocytic tumors that show hypodense areas on computed tomographic images, some intracranial tumors show hyperdense areas on CT images. The major reasons for hyperdensity on CT images are hypercellular lesions, intratumoral calcification, and intratumoral hemorrhage.
Where are lateral ventricular masses located in the brain?
Lateral ventricular masses were localized to three geographic regions: the trigone, the foramen of Monro, and the body of the lateral ventricle. An algorithm for the differential diagnosis was developed on the basis of the patient’s age at presentation and the location of the tumor within the lateral ventricle.
