Hi @tracyb and @megmor and cc to @cgrammie2. I was diagnosed November 2016 after a mini craniotomy at UCSF in San Francisco CA. I was being treated for a meningioma in the right cavernous sinus area since June 2009 diagnosed after getting terrible shooting pains and sudden double vision (the meningioma was pressing on the Trigeminal nerve and eye movement nerve). Had gamma knife treatment twice in 5 years. Then the numbness on the right side of my face occurred with dizziness and shooting electric type pain mostly in my eyes. The craniotomy biopsy result was inflammation mostly made up of B cells all around my dura. Was on prednisone 60 mg for about 6-8 weeks taper down. Currently treated for the second time with rituximab Infusions and doing okay. Please let me know how I can help and other questions you may have.
