The diagnosis of Multiple Sclerosis
is a clinicoradiological one. It is very important to correlate the patients symptoms and signs with the MRI
scan. Thus, a detailed neurologist
examination would be essential before making such a diagnosis.
Also, on MRI, modified McDonald's and Barkhof's criteria are applied before diagnosing MS and as per these two sets of criteria should be satisfied. In your case, 'dissemination in space' appears to have been satisfied but a repeat scan after 3 months (or this scan done after 30 days of symtpom onset) is needed to prove 'dissemination in time'. Dawson's fingers are classical in multiple sclerosis but we would need to see the scan to definitely say that the finger like projections described are definitely Dawson's fingers.
There are several other causes of subcortical white matter
signal abnormalities like those mentioned in your report. However, they may also be non-specific or age-related. The description in your scan fits
that of Fazekas Grade 1 (lesions not confluent) changes which are of no significance or worry, especially if you are above 40-50 years of age. However, if they worsen on follow up MRI, especially in young patients (less than 40 years), it maybe an indicator for predisposition to development of dementia
early in life.
Overall, it is probably a good idea for you to take an expert neurologist opinion and get a repeat scan done in 3-6 months, before coming to any conclusion.
