I posted a thread earlier about having headaches and weakness for the past couple of months. Initially they did a CT and MRI that showed a small nodule (6mm) in my brain. A month later, I had another MRI (this time with contrast) and the radiologist didn't note this spot, but it is still there. I went to the neurologist today and asked her about it and it is definitely still there (and looks more pronounced than on the MRI from a month earlier). My neurologist seemed dismissive of it and said it looked like a cyst, but not to worry about it because it's in the left frontal lobe ("an area of your brain that doesn't really do anything anyway") and is still small. She compared it to an MRI I had 9 months ago and there is absolutely no evidence of a cyst on it at that point.
My neurologist didn't seem to care about it, but should you do anything about a brain cyst that relatively suddenly appears? She said we could do another MRI in a year or so to make sure it wasn't growing ("to make me feel better"). What causes brain cysts (that aren't congenital)? Should I have any monitoring of it or treatment for it? (I do have a history of a tumour in my right orbital bone that was on the lining of my brain when I was a toddler, so being concerned about something in my brain does not seem to be entirely without reason).
Re: brain cyst?
I also would like to hear from somebody that is educated on this matter, in May my MRI showed a small arachnoid cyst in the anterior aspect of my left middle cranial fossa. I have been going through a lot with cervical neck surgery and the mri showed lesions on the brain so MS was suggested, all other tests negative. What concerns me is that I have been treated for severe pain behind my left eye, and also my left eyebrow and forehead are paralyzed, and I have been getting bad headaches, my neuro just says ehhh... and dismisses it saying we may never know what is causing that. He has also dismissed MS because all other tests came back negative. Yes we will monitor with MRI's .
