The one I had removed, I was told 1/16th of an inch from my optic nerve was, "dural based lesion along the left middle cranial fossa abutting the left cavernous sinus and left foramen rotundum." Whatever that means. I just know 2 neuro doctors told me not operable given the location but it was removed successfully. MRI follow ups show still not there. BUT, I am doing active surveillance on an .8 centimeter "enhancing lesion (meningioma) along the left aspect of the posterior superior sagittal sinus without evidence of superior sagittal sinus invasion." A follow up scan calls it out as "left posterior parasagittal." I also have a 6 centimeter one called out as "small right posterior falcine meningioma." They have not grown in the past year and I've already been told that if they do I would have radiation and not another craniotomy. So to answer your question, I think mine is also parasagittal but not invaded the superior sagittal sinus, and I sure hope it never does.

dchrzano: .6 centimeter falcine meningioma NOT 6 centimeters (typo error)

I’m reading from the report It says left frontal subcentimeter extra axial.
I have ask repeated where exactly it is and the answer is ask the neurologist but he won’t see the patients only get to see nurse practitioners.
