Colloid Cyst Synonyms

A colloid cyst, also known as a neuroepithelial cyst, is a rare type of brain cyst that typically occurs in the third ventricle of the brain. It is a benign growth that is filled with a gelatinous substance called colloid. Colloid cysts are usually small in size, ranging from a few millimeters to a few centimeters in diameter.

Colloid cysts are often asymptomatic and are incidentally discovered during brain imaging studies. However, in some cases, they can cause symptoms by obstructing the flow of cerebrospinal fluid (CSF) within the ventricles. When this happens, it can lead to a condition called hydrocephalus, which is characterized by an accumulation of fluid in the brain.

There are several synonyms used to refer to colloid cysts:

• Neuroepithelial cyst: This term is commonly used to describe colloid cysts due to their origin from the neuroepithelium, which is the embryonic tissue that gives rise to the central nervous system.


• Third ventricle cyst: Colloid cysts are predominantly found in the third ventricle of the brain, so this term is often used to describe their location.


• Colloid-filled cyst: This synonym emphasizes the characteristic feature of colloid cysts, which is the presence of colloid material within the cyst.


• Benign brain cyst: Colloid cysts are non-cancerous growths, so they are often referred to as benign brain cysts to distinguish them from other types of brain tumors.

It is important to note that while colloid cysts are generally benign, they can cause serious complications if they obstruct the flow of CSF. Prompt medical attention and appropriate management are necessary in such cases.
