Is colloid cyst a tumor?
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.

Colloid Cysts are benign cystic fluid collections that occur within the fluid-filled ventricles of the brain. Colloid cysts develop in the brain at the junction of the paired lateral ventricles and can cause blockage of cerebrospinal fluid (CSF) flow leading to hydrocephalus (excess brain CSF). As a result, these benign growths can cause headaches, ...

A neurological examination is often conducted to identify symptoms. This exam consists of assessing swallowing, sense of smell, sensation, hearing, eye movements, motor function, balance, and coordination. Also, an ophthalmologic examination may be performed to evaluate eye health and detect any problems.

One of the probable causes of hydrocephalus is a condition known as a colloid cyst.
What is a cyst in the brain?
Cysts are abnormal masses consisting of fluid enclosed within a membranous sac. Rarely, some cysts contain semi-solid or gelatinous substances as well. An example of this is a certain type known as a colloid cyst. This is a rare condition. Colloid cysts are generally associated with the third ventricle of the brain.
What causes a dilated ventricle?
Ventriculomegaly: An extra large colloidal cyst can cause the ventricles to become abnormally dilated. Increased intracranial pressure: The abnormal accumulation of fluid in the ventricles (hydrocephalus), if not addressed in time, can give rise to a buildup of pressure within the skull.
