Subependymomas are benign, slow-growing, brain tumors. They most often grow in the fourth or lateral ventricles, but may occur in the spine.[1][2] Some affected people do not have symptoms, while others may have headaches, changes in vision, and difficulty with balance. These symptoms are thought to be due to obstruction of cerebral spinal fluid (CSF) due to the tumor's location. The cause of subependymomas is not well understood. Surgery to remove the tumor is often curative.[2]
