The nervous system—the brain and spinal column—are surrounded by fluid contained in a membrane called the dura, which is primarily made up of connective tissue. The enlargement of this membrane (and sometimes the presence of cysts) is referred to as dural ectasia. Dural ectasia is present in more than 60 percent of people who have Marfan syndrome.
