Tumors that occur within the ventricles of brain are known as intraventricular tumors. They are
rare and benign tumors that may arise from periventricular structures such as the walls of the
ventricular system, the septum pellucidum and the choroid plexus. They can increase the
pressure inside the skull by obstructing the flow of cerebrospinal fluid.
Intraventricular tumors and lesions include:
- Colloid cysts
- Choroid plexus tumors
- Subependymomas etc.
Cause of Intraventricular tumors
The exact cause of intraventricular tumors is currently not known.
Symptoms of Intraventricular tumors
Intraventricular tumor that blocks the flow of cerebrospinal fluid causes symptoms of
- Speech, vision, or memory problems
- Mental status deterioration
- Permanent neurological defects
- Visual disturbances etc.
Some patient may also show following symptoms depending upon the location of tumor:
- Weaknesses, numbness or loss of sensations in the limbs
- Mood and personality changes
- Memory loss
- Language function impairments
Diagnosis of Intraventricular tumors
Diagnosis of intraventricular tumors requires the following:
- Detailed history of the patient
- Physical and neurological examination
- Magnetic resonance imaging (MRI)
- Computed tomography (CT scan)
