roz0606: This happened to me as well. I had a CT sinus scan in 2017; The report came back "no sinus infection."
But I kept have what I perceived as sinus issues as well as my left eyelid seeming to droop more than my right.
Slight "ghosting" of letters when I did close up reading. Saw an E.N.T. and eye doctor at least 3 or 4 times during a five year period always complaining of the same symptoms. Finally, a neurologist looked back at the 2017 CT sinus scan and found a 2.7 centimeter meningioma that was never cited by the radiologist. So, after reading your post, I guess it happens and hopefully is not that commonplace. The meningioma was removed in 2023 and it was in my sinus cavity and I was experiencing some of the same symptoms that you cited. A second opinon is always good.
