I had an mri and it came back that a small part of my brain had some inflamation. what the doctor said was its something non specific and not serious. what could cause this ? my gp said people who have migraines can have this on a scan?

People with migraine headaches can have nonspecific T2/FLAIR bright spots in their brain MRI, which can also be seen in white matter ischemic changes if older than 50, collagen vascular disease, vasculitis (inflammation of blood vessels), gliosis (scarring), Lyme disease, multiple sclerosis (diagnosed by spinal tap if you have certain symptoms when seeing neurologist).

Not feasible to determine cause of an MRI finding in absence of film review itself. Yes, migraine can result in white matter lesions, but so can head injury, smoking, and a host of other causes. If you wish more direct assistance, you could schedule a virtual consult on HT (www.connect@healthtap.com), but have films and report available at time.
