Of course, your doctor (or that of a 2nd opinion doctor) is your best guide. Do you have a previous MRI as a comparison?
I'm very new to MRI report forecasting but googling suggests to me this might be of interest (or completely not applicable):
"..... None of these punctate lesions have ever been reported to evolve into something significant, such as tumor, or to be a seizure focus, and therefore, in all probability they are of no clinical significance." ( spinwarp.ucsd.edu )
No, no previous MRI to compare
