Jimmylegs,
See link below for "Dawson's Fingers". My MRI didn't look anything like that. Mine had no pattern around any structure in my brain, it just seemed disseminated evenly as little bright spots, much like what you saw in Fig.1 and Fig.2 in the other link (although I didn't have quite the volume, still very similar.
Anyway, see link for an example of Dawson's Fingers:

Another MRI....
Here is an exact quote from my actual MRI report:
"
REPORT:
THE STUDY IS SOMEWHAT LIMITED DUE TO ARTIFACTS FROM THE PATIENTS ORTHODONTIC BRACES. THERE IS NO EVIDENCE OF INTRA-AXIAL OR EXTRA-AXIAL MASS OR HEMORRHAGE. THE VENTRICULAR SYSTEM IS NORMAL. THERE ARE NUMEROUS AREAS OF INCREASED SIGNAL INTENSITY WITHIN THE CORONA RADIATA AND CENTRUM SEMIOVALE BILATERALLY CONSISTENT WITH AREAS OF DEMYELINATION. FOLLOWING GADOLINIUM ADMINISTRATION, THERE IS ENHANCMENT OF A SINGLE PLAQUE NOTED INTHE LEFT FRONTAL CENTRUM SEMIOVALE. THE DIFFUSION WEIGHTED SEQUENCE REVEALS NO EVIDENCE OF ACUTE INFARCT.
IMPRESION:
1. NUMEROUS AREAS OF ABNORMAL SIGNAL INTENSITY WITHIN THE CORONA RADIATA AND CENTRUM SEMIOVALE BILATERALLY MOST LIKELY REPRESENTING AREAS OF DEMYELANATION.
2. ENHANCEMENT OF A LEFT FRONTAL CENTRUM SEMIOVALE FOCUS PERHAPS REPRESENTING AN ACTIVE AREA OF DEMYELANATION."
What I don't understand is that fact that there was a "single plaque noted". The MRI my neuro showed me appeared to have a lot of lesions everywhere... Does any of that report make any sense to anyone? blah

whoa those ain't my 'fingers'
hi v, my mri didn't look anyting like that df link above either. not at ALL. perhaps my neuro and mri tech were stretching a little to call anything dawson's fingers. i have maybe two spots in proximity to the corpus callosum, and the rest spread elsewhere. because of the slightly larger dimension in height versus width of my two pericallosal bright spots, they consider them to be vertically oriented and thus dawson's fingers. the fingers shown in the mri image you posted are drastically more developed and greater in number, not to mention connected to each other which mine certainly are not.
viper,
I think maybe your MRI report reference to a single lesion is referring to the enhancing lesion. The report distinguishes gadolinium enhancing versus nonenhancing lesions. On my report, I had multiple lesions, but only two that were still enhancing. Most significant, the enhancing lesions were in a region that corresponded with my symptoms that lead to me getting an MRI in the first place. My neuro predicted where in the brain a lesion would be, based on symptoms, if I indeed had a lesion. He turned out to be right. My understanding is that the enhancing lesions are the recent, "active" ones, and the others show older damage from past activity, but I don't know that for a fact.

I keep hoping my MS will take a more benign course, but that probably, with my luck, won't be the case.Ok, new report from my MRI on 07/10/06:
"The present study is compared to the prior exam of 6-21-05 and shows no significant interval change. Again note is made of significant artifact noted anteriorly, perhaps from the patient's braces. Scattered areas of abnormal signal intensity are again noted in the corona radiata and centrum semiovale bilaterally which could represent demyelinating plaques. No abnormal area of enhancement is noted on today's examinination.
IMPRESSION:
1. STABLE APPEARANCE OF THE MULTIPLE ABNORMAL AREAS OF INCREASED SIGNAL INTENSITY IN THE CORONA RADIATA AND CENTRUM SEMIOVALE BILATERALLY WITHOUT EVIDENCE OF NEW ENHANCEMENT."
So I guess that means that MRI showed no areas of active inflammation, which is not to say there isn't damage being done, just to say that there is no inflammation. Right?
I'll have my MRI images available via CD tomorrow, I'll try to post some so you all can see my brain (make sure you have a magnifying glass ready!).
