I am concerned about one MS lesion I have that was found in 2015. Every 6-9 months I have had another MRI scan the lesion is still showing active with contrast. It isn't doing any damage but hasn't died out. Most lesions die out after few weeks. Doctor says it is a MS lesion. Don't understand what is going on with this strange lesion and why it just don't quietly die out. Is this rare? My doctor is a MS Specialist but does not explain a lot. Feeling uneasy!
It is rare to have a demyelinating lesion continuously enhance for that long. Persist enhancement raises questions about a vascular malformation among other possibilities. I would have a conversation with your neurologist about your concerns and if you do not get an acceptable answer, you can always obtain an independent second opinion.
