People with migraine often have plaques on their MRI
that are of
unclear cause or significance.
Other causes of
plaques on MRI
can usually be distinguished based on history and
symptoms, such as symptoms of neurologic deficit (for example arm weakness or difficulty walking etc). These can also be distinguished based on the MRI appearance. These include, but are
not limited to, multiple sclerosis, other demyelinating disease, and
inflammatory processes such as vasculitis, etc.
