Colloid Cyst in New York, NY

A colloid cyst is a benign, fluid-filled growth located in the third ventricle of the brain, and it may require surgical treatments, like shunt placement, craniotomy, endoscopic craniotomy, or simply observation. Filled with proteinaceous fluid, colloid cysts are not considered "true" brain tumors but are categorized as intraventricular tumors, which can sometimes cause symptoms necessitating intervention. These cysts can interfere with the proper balance and circulation of cerebrospinal fluid, which normally nourishes and cushions the brain and spinal cord. Colloid cysts are usually attached to the roof of the third ventricle or to the choroid plexus, both vital areas for fluid and blood circulation, and their obstruction can cause hydrocephalus and increased intracranial pressure, leading to potentially serious or even life-threatening consequences. Representing 15 – 20% of all masses in the ventricles, colloid cysts are a significant concern in brain health and require proper evaluation and treatment by Dr. Raymond Sekula at his office in The Neurological Institute of New York in New York, NY.

Symptoms of a colloid cyst can vary depending on its size and the degree to which it obstructs cerebrospinal fluid (CSF) circulation. Many small cysts remain asymptomatic and are only discovered incidentally during imaging for unrelated issues. However, larger cysts or those that interfere with CSF flow can lead to increased intracranial pressure, causing symptoms such as persistent headaches, nausea, vomiting, dizziness, and difficulty with balance. These headaches are often positional, meaning they may worsen when lying down or with sudden movements. In more severe cases, a colloid cyst can lead to episodes of confusion, memory difficulties, personality changes, or sudden loss of consciousness, particularly if hydrocephalus develops. Patients may also experience blurred or double vision, as pressure within the brain increases.

A colloid cyst is typically diagnosed through imaging studies, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, which can reveal the cyst's presence in the third ventricle of the brain. These imaging techniques help assess the cyst's size, location, and potential impact on cerebrospinal fluid flow. In some cases, a neurological examination may be conducted to evaluate symptoms like headaches, memory deficits, or balance issues that could be associated with a colloid cyst. Early and accurate diagnosis is crucial for determining the appropriate treatment plan.
