Abstract
You are most likely to develop an arachnoid cyst in your head but it may also form around your spinal cord. It is called an arachnoid cyst because it exists between your brain or spinal column and your arachnoid membrane in the space between it. This is one of three layers of the membranes that surround your brain and spine. If you develop an arachnoid cyst in your head it will expand between your brain and skulls or bags, called ventricles around your neck. Cerebrospinal fluid (CSF) is loaded to arachnoid cysts. CSF is a calming fluid that exists naturally and covers the brain and spinal cord. The arachnoid cyst walls don't allow this fluid to drain into your CSF system, allowing it to build up within.
