Yes, an MRI of the brain is definitely needed now.
In fact I am surprised they haven't ordered an MRI of the brain already
Someone with lightheadedness + disequilibrium definitely required a brain MRI
Brain MRI will help in exploring any structural abnormalities in the brain causing your above mentioned symptoms
You actually have had almost all other investigations which are important too because your symptoms may be coming from the ear, eyes, neck etc, but the brain possibility hasn't been explored yet, so brain MRI is definitely needed now.
So please insist on ordering an MRI of the brain with your doctors. It should be MRI with and without contrast injection to get the best results.
If you have any pathology or abnormality in the posterior fossa structures then you can get the above mentioned symptoms. Posterior fossa includes cerebellum, brain stem and cerebello pontine angle areas.
Pathology or abnormality in these areas can cause your above mentioned symptoms like lightheadedness and disequilibrium and MRI is the best investigation to look at these areas of the brain.
While stress & neck positions too can cause your symptoms but before giving these diagnoses we need to rule out brain pathologies causing your symptoms, so brain MRI is very much indicated in your case.
Thanks . SInce both neuros didnt suggest it after their exams (both at Mass General, a great hospital) , I didnt want to "play doctor" - and one said the cerebellum all looked fine on the upper cervical scan and that is where he would be looking anyway. I will bring it up again
You are very welcome!
The cervical scan can miss it
So ideally brain scan is needed
Brain MRI can thoroughly look at cerebellum, brain stem & cerebellopontine angle areas
The cervical scan cannot thoroughly look at these areas
cervical scan will look only partially these areas, so brain MRI is definitely needed in your case
So please insist on getting the brain MRI
Do you have any further questions?
just one. My vestibular PT think its a combo of very high astigmatism in my eyes (not fully correctable) and a potential inner ear issue on my left ear. she feels that MRI hasnt been asked for becasue i have no other symptomology
Okay I see. I will explain now
When it comes to symptoms they are highly nonspecific
What it means is same symptoms can be produced by varieties of pathologies
the lightheadedness and disequilibrium can be produced by neck, ear, eye & brain
Clinically there is no definite way of telling these symptoms are coming from where
we can only assume it is coming from ear, or eye, or brain etc, but the only certain way of finding out from where these symptoms are coming is by properly investigating
accordingly a brain MRI is needed in your case
