Does anyone know if lesions to determine ms have to be located in a certain area of brain to be MS lesions?

Forgive me if this was addressed before, having trouble keeping up lately.

Thanks in advance.

That's what I was told while waiting to be dxd.
I was dxd based more on symptoms, I guess. My current neuro said if he'd seen my MRI, he wouldn't guess that I had full-blown MS, but my sxs sure do confirm it...

My MRI was crystal clear MS... said periventricular (I believe) area of the brain, and another area that I don't recall... but the lesions and locations were typical of those in MS, however when my regular doctor saw the MRI, before I saw the neuro, they said the lesions could be from other causes.

Which is why MS can't be diagnosed based on positive MRI results alone.

It's good that my MRI was so telling, and my lumbar puncture came back with o-bands, because my symptoms were, for the most part, not hallmark MS symptoms, but vague neurological symptoms that can show in many mimic diseases.

i don't know if they have to be in certain areas but my mri showed lesions in the corpus callosum

MS lesions most commonly involve white matter areas close to the ventricles of the cerebellum, brain stem, basal ganglia and spinal cord; and the optic nerve.

I've heard lesions in the frontal lobe is usually MS related??
