Meaning of T2 hyperintense signal on MRI
Does a "focus of T2 hypersensitivity" on an MRI always mean a lesion, or can it mean something else?  Also how common are such findings that are "nonspecific"?  Can a person have such a finding and still be normal?

a focus of T2 hyperINTENSITY means that the signal from that area has different tissue characteristics compared to normal brian tissue. Usually this is due to an increased water content of the tissue. Pathological tissue usually has more water than normal brain so this is a good type to scan to pick this up

however it does not reveal any information about what it is although the site and pattern of abnormality does. A few focuses usually does not mean significant pathology and can be due to migraine, hardening of the arteries, high blood pressure or more rarely a demyelinating disease or vasculitis.

A person can have plenty of them and be asymptomatic

Another possible cause of these white matter lesions could be Lyme disease. That is the case with my hubby.

Go to http://*************** and click on Flash Discussion and then Medical

Also I have read that such lesions could be caused by celiac disease.

Best Wishes
