Endoscopic Cyst Fenestration

What are arachnoid cysts?

Arachnoid cysts are fluid filled sacs found in the spine and brain. These growths typically form between the skull base and the surface of the brain or directly on the arachnoid membrane, one of the three major membranes that converge over the brain and spine. Although these cysts are less likely to occur in the spine, they could potentially develop in this highly sensitive area of the body. Arachnoid cysts are commonly occurring intracranial cysts often located in the posterior fossa, suprasellar and temporal fossa regions. The vast majority of arachnoid cysts are asymptomatic and incidental as they are usually present from birth. This means that you will not have any symptoms and it is not causing any problems but was just found because you did a scan for another reason. Some arachnoid cyst are however very large or expand with time and will require some form of treatment.

What are the signs of arachnoid cysts?

Symptoms of arachnoid cysts depend on the location and size of these abnormalities. Small cysts are often asymptomatic. However, large cysts can result in cranial deformity due to hydrocephalus, which is common among younger children and infants.

General signs include the following:

• Headaches, which progressively worsen in the mornings
• Nausea or vomiting
• Elevated intracranial pressure
• Poor development (developmental delay)
• Significant changes in behaviour
• Visual interruptions
• Seizures

How do you diagnose arachnoid cysts?

A neurological exam is a widely performed procedure to investigate symptoms and identify potential issues. However, imaging tests are an integral part of the investigation. Detailed assessments such as magnetic resonance imaging (MRI) and Computed tomography (CT) scans are conducted to evaluate the mass properly.

How do you perform endoscopic cyst fenestration?

Endoscopic cyst fenestration is a less invasive surgical procedure that entails the use of a tiny camera and surgical tools to create a hole in the cyst, enabling fluid to seep out seamlessly.

Fortunately, endoscopic cyst fenestration, a less invasive surgical procedure, offers significant benefits. It reduces recovery time and safeguards the health of the surrounding brain tissue. The procedure can alleviate headaches, improve vision, reduce the size of the cyst, and lead to optimal recovery, giving hope to those affected by arachnoid cysts.
