Thank you for posting your query at DoctorSpring.com
I have noted your symptoms and MRI brain findings.
I agree that it is unlikely to be a tumor.
These white matter lesions are most commonly seen in migraine. Other common causes are ischemia (lack of blood flow to brain) or demyelination (such as multiple sclerosis). MS is unlikely with a single lesion.
In conclusion, there is no need to worry about that lesion on MRI brain, as it can not be anything serious. Repeat MRI brain may be done, if there are new symptoms such as worsening headache, numbness or weakness of arm or leg.

Patient replied :
Do you think that if it were a tumor symptoms would have progressed after all this time? Can migraines cause just one lesion to form? My neurologist never mentioned that migraines can cause lesions on the brain.
Thank you for getting back.
Yes, if it were tumor, symptoms would have progressed over time.
Migraine can form just one lesion. I am not sure why your neurologist dId not mention, but migraine is one of the commonest causes of while matter lesions on brain MRI.
