Hi and welcome,
Your MRI isn't providing enough consistent-suggestive evidence for MS to be on the top of your list of possible causes, unfortunately a few non enhancing periventricular lesions wouldn't be particularly suggestive of anything specific.....what minor MS symptoms are you experiencing?
Just want to say that I have found this forum very helpful in understanding MS.
This week I was lucky to see a neurologist and MS is on the list of possibilities, but so is Lupus, Sarciodosis, and metabolic issues such as B12 deficiency. Thanks to this site, the list of possibilities did not come as a surprise.
The neurologist took ample time to ask questions and complete a neurological exam. Over the next few months I will be busy getting bloodwork, Xray, LP, spinal MRI. Hopefully by late summer or fall we'll have a better understanding.
