My son (7) has brain tumors. He also has a cyst in his cerebellar region that causes some pain, but no other complications. He has a disease Neurofibromatosis, which can cause these cysts, in the brain and along the spine area. This disease is easily diagnosed with visible cafe au lait spots on the skin. Or most commonly called more than 4 birth marks on your body. Best to check it out. Much luck!
