Arachnoid cysts, a type of brain tumor that are very difficult to detect are cerebrospinal fluid cysts that develop in the membrane that protects the brain. These cysts typically form as a congenital disorder but may also be caused by head injury, meningitis and brain tumors. Also, men are 4 times more likely than women to develop arachnoid cysts.

Many patients do not show symptoms, making it difficult to measure the true occurrence. However, it is still imperative to be informed on the common effects of arachnoid cysts. Severe neurological damage, including spontaneous hemorrhages and seizures, can occur as a result of untreated arachnoid cysts.
