D42.9: Neoplasm of uncertain or unknown behaviour: Meninges, unspecified
When there is abnormal growth of tissue, then this is also referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant.
On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges. You have abnormal growth of tissue in the membranes (linings) of your head or spinal cord.
