Round lesions

[truelove47]

Hi everyone

I was wondering about the shape of lesions  On my last mri report, it said I had 15 perfectly round Lesions.

Round or oval?   Is there a significant difference?  thank you guys

best wishes to all

Linda      ( I feel so dumb)

Thank you for taking the time to answer my question

Even though I have had this ms for over 23+ years I really am not educated
or knowlegable on the mechanics of it.  Just reading about it difficult for me to wrap
my brain around it.  I simply don't understand.  I do know all of my symptoms because I have experienced  them

You all are wonderful writers and I am good at flapping my mouth, LOL
sho    You are great      ty

best wishes and thank you again                        
Wishing everyone the best                          Linda

I don't know anything about this either, but I poked around a bit and it doesn't appear that it's unusual for them to be round so I wouldn't worry about it.

According to MRI Atlas of MS Lesions by Mohammad Ali Sahraian and Ernst-Wilhelm Radue (which sounds like a really good book with a lot of examples for those who can't resist trying to read their own MRIs):

"Multiple hyperintense lesions on T2- an PD-weighted sequences are the characteristic magnetic resonance imaging (MRI) appearance of multiple sclerosis (MS). The majority of lesions are small, although they can occasionally measure several centimeters in diameter. Focal MS lesions are usually *round* or *oval* in shape and relatively well circumscribed.

"MS lesions may occur in any part of the central nervous system where myelin exists, but lesions around ventricles and the corpus callosum are highly suggestive. Other common sites of involvement are subcortical and infratentorial regions. Although MS is a white matter disease, a subset of lesions may involve gray matter, including the cerebral cortex, thalamus, and basal ganglia." (p. 3)

"Classic" MS lesions are oval. However, and this is a big however, many and maybe most MS lesions are not classic. That does not mean they are not MS, and no good doctor would insist that. It's just that the disease is easier to diagnose with the classic variety. Other shapes could possibly represent other conditions.

When the MS specialist gave me the mini-lesson in classic MS lesions he said "they like to be long and reach toward the lake" (ventricles).  The pictures I've seen of Dawson's fingers type lesions are indeed shaped like that.

If I remember correctly from the Consortium lecture and slides about MRI, there were oval and round lesions pointed out.  That's about all I know.

Hi again,

I wanted to add that my neuro is Not a lesion counter. The image center where I had the mri done is where I live. This image center counts lesions           My neuro is 100 miles from where i live           I delivered the cd and printed results to him  I noticed the PERFECTLY ROUND
sentence, and what I read the the health pages , it said classic MS lesions were oval.

I am curious about the wording  Thanks again           Linda
