For years I've also been having issues with double vision and right eye droop. Seen diff specialist to try and figure this out as they reassured me my issues were not from my meningioma. Suddenly after my annual scan (yearly after gamma knife) they saw a second located in the cavernous sinus area and it was there all the time when they go back to my imaging. At a loss and now trying to see what the next steps are for this. In such shock as to how this could be missed from at least 5 yrs of images.
