This 25 year old man was unfortunate to have meningioma - a tumour growth that is located in his upper spinal canal. The tumour compressed the spinal cord and causes hydrocephalus. He was treated with cyberknife in nov 2006 over 10 fractions. His symptoms started to improve after day 3 and 3 weeks after treatment, he has gone back to work. Neck stiffness that he had previously, has reduced tremendously.
