At the age of 35 yrs old in 2005, I was never one to ever get headaches. One evening in early October 2005 I had a very bad deep headache that didnt go away for 8 days. I was to the ER; CT Scan, blood work, EKG, etc... Was told it was stress. Fast forward, 8 months and 2 more CT's of nothing there I finally was given approval for MRI. There was the colliod cyst measuring the size of a quarter with hydro. One month later, had a bifrontal cranitomy, July 2006. Every two years I still get an MRI, no regrowth.
