MRI 13th One....

I just had my 13th MRI the other night. It states that there are no new changes… that is awesome… but what does involvement of the corpous callosum mean??? also, similar abnormality within the pons?

I studied all of my previous MRI reports and not one of them mention this before.

I have been feeling awful… Does anyone know what this means?? I am not seeing my doctor until next week.

Thank you!!
