A colloid cyst (AKA neuroepithelial cyst) is a benign tumor most commonly found in the 3rd ventricle in the brain. The contents of the cyst resemble gelatin or glue. In fact, the term “colloid” is derived from the Greek word Kollodes meaning “resembling glue.” Although the tumor is considered benign and is generally asymptomatic, it may lead to sudden death or coma in rare cases; therefore, treatment is highly encouraged.

• Magnetic resonance imaging (MRI)
• Computerized tomography (CT)

How is a colloid cyst treated?

• Surgical removal - This is the definitive method of treatment for a person with a colloid cyst. Options include complete removal (several surgical techniques available) or cyst aspiration (drainage of fluid). Since the tumor is benign, chemotherapy and radiation are not indicated.
• CSF shunt- If surgically removing the cyst is considered too high risk or if hydrocephalus continues despite removal/drainage, the neurosurgeon may decide to place a shunt so that the cerebrospinal fluid (CSF) is able to bypass the obstruction.
