Can you please explain my MRI of the brain done with and without contrast please: On T2 weighted and FLAIR sequences, there are multiple subcentimeter round ovoid foci of high signal in the right frontal lobe periventricular white matter, in addition to several subcentimeter lesions in the periventricular and subcortical white matter in the left frontal lobe and the subcortical white matter in the posterior right frontal lobe.
When I was 28 my brain MRI scan had 7-8 lesions, a couple that were several cm in diameter near the corpus callosum, which gave worry that I had MS even though I was ultimately diagnosed with Lyme.
Lyme does not always cause lesions, though. Many people very sick from Lyme for a long time will have normal MRI's. Lyme is not diagnosed through MRI, but it can be diagnosed by blood tests and/or clinically through symptoms.
Do you think you have Lyme disease?
im 30 years old i got a mri a few years ago and it said i had two high signal lesions on my brain i just wondered if you could shed any light on this for me ??? i dont understand what it means ? i have been having problems with my health for over 10 years fatique memory problems dizzy vision problems and strange pains all over . i have been in and out of doctor surgeries with no clear cut answers .
Remyelination (repair of the damaged covering of the nerve) is a pretty slow process. Some lesions hang around for years. The lesions show up on T2 and FLAIR sequences of the MRI. The GAD contrast that is used in brain imaging will enhance "new" lesions that are about 40 days or newer on the T1 sequences. The other thing that shows up on the T1 sequences is "Black Holes" or areas of nerve axon damage.
Volume of the t-1-hypointense lesions in the juxtacortical, periventricular, infratentorial and deep white brain regions from the patients scan. Lesions appearing hypointesnse in T1 an hyperintense in T2 Flair MR images. Brain Structure Volumes: The pink color in the normative percentile column indicates a brain tissue volume about the 95th percentile or a ventricle volume below the 5th percentile, these values are outside the normal range, but not necessarily of diagnosic concern.
The appearance of these tumors on MRI are distinct and can be differentiated from MS. Infections can also cause lesions in the brain such as cryptococcus, brain abscess, and tuberculosis.
I suggest you discuss with your neurologist regarding the MRI findings to know if the characteristics of the lesions would point out to MS or any other conditions that I mentioned above.
Wishing you all the best and hope that you and your doctor can get to the bottom of this. Regards and God bless...
Contrast most likely would not make a difference if you have had symptoms for more than 40 days and there are no T2 lesions on a 3.0 Telsa MRI, I kind of doubt they would have seen any enhancing lesions on a post contrast T1 PD/PSE sequence.
GAD should not make the symptoms worse. GAD can be rough on the kidneys, but that is about it.
My first brain scan showed a lot of small perventricular lesions and my two bigger ones were on the occipital lobe and frontal lobe so I don't think they could be causing these symptoms.
I guess I am just wondering if I should expect anything to show or if my sx are just too transient that if there are any lesions on the c-spine that they won't be detectable. I do not know what strength the machine is but I doubt it is more than T1.5-T2.
Thanks!
Hi, can you tell me the difference in brain lesions from MS and lesions from vascular migraines? I was diagnosed with multiple brain lesions seen with T2. It said that they were not ovoid in shape or tranversely oriented. Can you tell me what this means? I have suffered with migraines for 34 years. I have both aura and non-aura migraines. Could these lesions be related to the migraines?
Well after 4 long weeks of waiting for my MRI scan, i arrive at the MRI unit yesterday evening only to be told as im getting onto the scanner that my MRI has been requested without contrast. i did try to tell the radiographer that it should have been with contrast as it was to diagnose MS.
The radiographer told me that contrast didnt matter and that MS would show on the type of scan they were doing (i know this not strictly true).
Hey Doc,
This year I experienced a tremor in my left hand, cognitive problems including; feeling foggy, short term memory problems, a general sense of malaise and uneasiness and balance difficulties. I had an MRI which stated "Multiple T2 hyperintense lesions are identified within both cerebral hemispheres, the largest in the periventricular white matter of the right temporal lobe. No definite diffusion abnormality or abnormal contrast enhancement to suggest active lesions.
The lesions it describes are in the noncerebellar parts of the brain. It looks like that the first time, you had a brain and C-spine scan or that the brain scan caught the C-spine, too, but the second report references only brain structures, so it may be that the C-spine was not scanned the second time or that the radiologist simply didn't see anything there to comment on; however, usually, they'll remark that they didn't see anything just to make it clear that they looked.
If you are having Occipital Neuritis and Arm Symptoms, you need to scan the brain and C-Spine. If the symptoms are in the lower limbs, you need to scan the brain, C-spine and T-spine.
Your doctor may also decide to scan the L-spine, not looking for lesions, but looking to see if lower limb symptoms could be the result of compression of the Cauda Equina, the horse tail nerves that go to the lower extremities.
