Can arachnoid cyst cause the skull fracture easily. My friends daughter has a right on top of an cyst. to thin or soften?

An arachnoid cyst is an abnormal collection of cerebrospinal fluid (CSF) within the arachnoid membrane, one of the three layers of tissue that surround the brain and spinal cord. Arachnoid cysts are usually benign and do not cause any symptoms. However, in rare cases, they can cause complications, such as seizures, headaches, or vision problems.

Arachnoid cysts can occur anywhere in the brain or spinal cord, but they are most commonly found in the middle fossa of the skull, which is the area behind the forehead and above the eyes. This location makes them vulnerable to injury from head trauma, such as a car accident or a fall.

If an arachnoid cyst is located on the top of the skull, it is less likely to cause a skull fracture than an arachnoid cyst that is located in the middle fossa. This is because the top of the skull is thicker and more resistant to injury.

However, even an arachnoid cyst on the top of the skull can cause a skull fracture if the head trauma is severe enough. In these cases, the arachnoid cyst can put pressure on the skull, causing it to crack or break.

If your friend's daughter has an arachnoid cyst on the top of her skull, it is important to take precautions to protect her from head trauma. This may include wearing a helmet when playing sports or engaging in other activities that could result in a head injury.

It is also important to see a doctor regularly to monitor the arachnoid cyst and ensure that it is not causing any problems. If the arachnoid cyst is causing symptoms, surgery may be necessary to remove it.
