ARACHNOID CYST Meaning and
Definition
-
An arachnoid cyst is a fluid-filled sac located within the arachnoid membrane, one of the three protective layers covering the brain and spinal cord. This type of cyst typically develops before birth or during early childhood as a result of an abnormal splitting or tearing of the arachnoid tissue. Arachnoid cysts are considered congenital, meaning they are present at birth.
The size and location of these cysts may vary greatly, but they are commonly found in the brain's middle fossa or around the base of the skull. Arachnoid cysts are often filled with cerebrospinal fluid (CSF), a clear fluid that surrounds and protects the brain and spinal cord. As the cyst grows, it puts pressure on nearby structures, potentially causing symptoms.
Symptoms associated with arachnoid cysts depend on their size, location, and the age of the individual. In some cases, they may remain asymptomatic and go unnoticed. However, if the cyst grows large enough, it can lead to various neurological problems, including headaches, seizures, developmental delays, difficulty with balance or coordination, vision problems, and localized pain in the affected area.
Diagnosis of arachnoid cysts typically involves imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. Treatment options for arachnoid cysts vary depending on the individual, the size and location of the cyst, and the presence of symptoms. In cases where the cyst is causing significant symptoms or poses a risk of complications, surgical intervention may be necessary to remove or drain the cyst. Regular monitoring through imaging tests is often recommended to ensure the cyst's stability and assess any changes over time.

Etymology of ARACHNOID CYST
The word "arachnoid cyst" is derived from the combination of two terms: "arachnoid" and "cyst".
1. Arachnoid: The term "arachnoid" originates from the Greek word "aráchnē" meaning "spider's web". It refers to the arachnoid mater, which is one of the three membranes (meninges) that cover the brain and spinal cord. The arachnoid mater has a delicate, web-like structure resembling a spider's web.
2. Cyst: The term "cyst" comes from the Latin word "cystis" or the Greek word "kustis", both meaning "bladder" or "pouch". In medical terminology, a cyst refers to an abnormal, fluid-filled sac or pocket that can develop within different tissues or organs of the body.
