I've had two meningiomas, 3cm each, one removed by traditional surgery on August 1 of this year, then an emergency surgery to deal with an infection that was not within the skull. Am waiting to decide what to do and when to do it regarding the second meningioma which is on right front area above my eye, evidently near or on a vessel. Neurosurgeons evidently often recommend people with meningiomas wait to see how or if it is growing before determining surgery is needed, and what kind. I had dizziness and slight fainting spells before removal of my first meningioma which was due to the fact that the meningioma was pressing on the optic nerve and causing bleeding and pressure. I had believed I was just consuming too much coffee/caffeine! After having the stitches out this past Friday from my last emergency surgery I'm experiencing some headaches and dizziness. I will be contacting my surgeon today to see if that is because removal of stitches has caused more infection. Since meningiomas are most often benign, surgeons take a wait and see attitude, again, to see how it is acting and take MRIs every 3 months or so. Each situation is unique, so ask your dr about the symptoms you're having.
