What are the signs and symptoms of arachnoid cysts?

In some cases, arachnoid cysts do not cause any symptoms.[1] The location and size of the cyst in each individual determine whether symptoms occur, as well as when they might begin. Most individuals develop symptoms before age 20, and especially during the first year of life. Signs and symptoms of arachnoid cysts that are located around the brain may include headache, nausea and vomiting, seizures, hearing and visual disturbances, vertigo, and difficulties with balance and walking. Arachnoid cysts located around the spinal cord can compress the spinal cord or nerve roots and may cause symptoms such as progressive back and leg pain, and/or tingling or numbness in the legs or arms.[2][3]
