Sorry, I can’t answer your question. In my opinion, they should not send out this guff, as it means nothing until it’s interpreted for you by a neuro - which is the purpose of the follow-up appointment.
I was under the impression MS lesions were pretty distinctive - at least to someone experienced in what they’re looking for. But the radiographer seems unconvinced about yours, which may mean it’s just one possibility.
MS is the commonest cause of demyelination, but the report doesn’t even say for sure that you have demyelination. You’ll have to wait for the neuro’s reaction, I’m afraid.
Even if he thinks it is demyelination, it doesn’t mean you will proceed immediately to a diagnosis of MS. The diagnostic criteria for MS require proof that it’s an ongoing or recurring issue over time. It’s not usually possible to confirm this from a single scan, because all that provides is a snapshot in time - they can’t tell if all the spots/lesions/whatever got there at the same time, or if it’s been slowly, over months or years.
Usually, the only way to find out if it’s an ongoing thing is (a) wait for new symptoms, or (b) scan again in a number of months to see if anything has changed.
Otherwise, all you know is something happened sometime, but you can’t prove it’s ongoing, which is part of the definition of MS.
