New MRI

[Peg409]

My husband had a new set of MRI's on the 19th, the following is the report:

***this is an Amended report***
No abnormality is identified on diffusion imaging. A single flair hyperintense focus within the right corona radiata is noted. There is no significant enhancement following contrast. No pattern of flair signal abnormality along the calloseptal interface is present. The ventricles and sulci are otherwise normal in size and configuration. A single vessel arising from the cavernous segment right internal carotid artery courses along the inferior middle cranial fossa/underside of the temporal lobe. The vessel appears to contact the right transverse sinus. The basal cisterns are intact.
Addendum: The exam was compared to MRI brain of 3/30/12

Impression: Single flair hyperintense focus within the right corona radiata. No specific pattern of flair abnormality suggestive of MS. No Infarction.
Anomalous vessel arising off the right cavernous carotid artery appearing to join the right transverse venous sinus. This may represent a small AVM or AVF. This may be further visualized with CTA of the head.


I understand the second half of the report about the AVM/AVF, but I think I'm lost as to why the lesion in the right corona radiata is not suggestive of MS, keep in mind my husband was told in 1994 that he had MS. I also don't see a comparsion to the previous MRI. Any ideas or suggestions? What do you all think about this MRI?

Anyone had any other idea?

I found this information at:   http://www.msif.org/en/research/ms_research_news/brain_lesion_loc.html

Results: People with CDMS were significantly more likely than those with CIS and abnormal scan 20 years after onset to have T1 and T2 lesions in the corona radiata, optic radiation, and splenium of the corpus callosum (periventricularly) and T2 lesions in the right fronto-occipital fasciculus. People with MS EDSS >3, compared with those with EDSS ≤3, were more likely to have optic radiation and left internal capsule T2 lesions. No significant difference in lesion distribution was noted between RRMS and SPMS.

But I'm not sure if that helps us or not. Thanks JJ

Hmmmm not sure if they can with enough acuracy, compare a 1T with a 3T, if i recall correctly the comparrison stats say a 3T will show 25% more lesions than a 1.5T does. The latest MRI should technically provide more information but there doesn't seem to be anything apart from that one white matter lesion in the corona radiata, and if i've read it right thats more commonly associated with stroke or TIA's. So i'm thinking because an AVM is usually a congenital abnormal connection between veins and arteries, btw both do have sx's similar enough to the sx's of MS, this MRI could be indicating there is a vascular issue rather than MS.

about.com has this definition for the corona radiata:

"Definition: A bundle of nerve fibers that carries information to and from the brain cells that make up the cerebral cortex, an area of the brain that is responsible for the processing of conscious information. "

Sorry i couldn't be of more help, its definitely not what we commonly read in an MS MRI report, out of my depth so i hope someone else can help out.

Cheers..........JJ

I forgot to mention, the MRI in March was on a 1T and the new MRI was on a 3T.
