What are the symptoms of Arachnoid cyst? icon plus
The symptoms associated with an arachnoid cyst vary depending on its location and size. Many cysts are completely asymptomatic.
If the cyst is symptomatic, it can cause neurological problems related to its location.

How are Arachnoid cysts diagnosed? icon plus
Your consultant will speak to you about your medical history and perform a physical examination. You may also need to undergo one, or both, of the following tests to confirm a diagnosis:
- MRI scan. During an MRI scan, a magnetic field is used to create cross-sectional images of your brain. These images show the brain and spinal cord in very great detail.
- CT scan. These use X-rays to show the bone of the skull and spine, which show up less well in MRI scans.

Potential treatment options icon plus
Treatment is generally recommended only when your cyst is symptomatic. In such cases, options may include:
- Surgical placement of a cerebral shunt. This is a medical device that relieves pressure on your brain caused by an accumulation of fluid. One end is usually placed in the cyst, with the other end in the normal CSF.
- Drainage of the cyst fluid by cutting a window in the membranes through a surgical operation.
