Hi , I had a very large meningioma and surgery for it in June of 2016. I suspected I had a brain tumor because I had headaches and dizziness for two years prior . My insurance at the time refused to do a CT of my brain. I ended up in the ER at the university of Iowa hospital where I had emergency surgery. It was huge and caused a midline shift in my brain of 8mm It was benign. I later discovered a resident did my surgery and apparently their was not an attending staff Dr. at my surgery. Long story short , Six months after surgery I had terrible headaches along the incision line on my head and discovered some of the screws and plates on my skull were moving. I was told nothing was wrong so I referred myself to Mayo this fall. Mayo did surgery to remove all of the plates and screws that were put on my skull. Many plates and screws that were used were loose and hanging out!!! Long story short I highly recommend Mayo. If they can do gamma knife surgery for you I would do it! It's less invasive and you would be less likely to have the issues I did! Meningioma s can come back but I believe if they are benign it's less likely !! Good luck with your upcoming surgery!
