Had brain scan and results from lumbar puncture not sure what they mean?

Hi there,
I am currently going through the diagnosis stage of ms i have had a brain scan where they have found legisons and i also have had a lumbar puncture which has come back with a letter with alot of medical jargon the onky positive thing on it was that some oligoconal bands consistant with intrathecal synthisis of igG. If anyone has any insight into this i would be really greatful as i have a few months until my appointment with nuroligy.

Thanks
Flossi
