FAQ - Gliosis
(Powered by Yahoo! Answers)
9 years ago i had cerebral shunt installed, todays cat scan reveals gliosis formations which from what i
have read are findings seen in Parkinson, Alzheimer and neurodegnerative disorders, does its presence in my brain today enhance the possiblity of developing these disorders.
yes, sad to say, it likely does. (+ info
What is gliosis?? It has to do with the brain or somthing??
Gliosis is a proliferation of astrocytes in damaged areas of the central nervous system (CNS). Astrocytes are relatively large glial cells and are the connective tissue cells of the CNS. Astrocytes have various functions, including accumulating in areas where nerve cells (neurons) have been damaged. Gliosis and neuronal loss in certain brain regions are findings seen in various neurodegenerative disorders such as Korsakoff's syndrome and AIDS dementia complex. (+ info
Can someone explain this MRI report to me please?
Here is what it says. A 4 mm and a 3 mm focus of abnormal t2 bright signal are seen in right parietal white matter. No other abnormality is identified. No abnormal patterns of enhancement are seen following administration of IV gadolinium contrast. These probably represent areas of nonspecific gliosis. Low grade glioma is less likely.
I had this done recently because I passed out and they think I had a seizure. I am a 44 yr. old woman with a long history of high blood pressure. They did a cat scan first which didn't show anything. Also where exactly is the right parietal white matter at in your head and what does it affect?
The outer 3/8 ths of an inch on the surface of the brain is where most of the brain cells are and is called grey matter because of how it looks on an autopsy. The area underneath is called white matter (again because of what it looks like on an autopsy) and consists of all the nerve fibers which come from the brain cells.
The spot described on the MRI is a pea sized area, probably about two inches or so above the top of your ear and about one inch under the surface of the brain. These kinds of spots are common in adults and usually carry no significance if there is only one. Tumors enhance with IV gadolinium contrast so it pro ably cannot be a tumor. It also should not have anything to do with seizures because they originate from grey matter (the surface) and not from the white matter deeper in the brain. Most people who have one of those spots have nothing wrong with them. (+ info
Help understanding my MRI results?
I had an MRI in October and was told I had a venous angioma w/ a peri lesional gliosis. She explained the venous angioma - but what the heck is a peri lesional gliosis?
'peri-' is a prefix meaning 'around'
'lesion' means 'injury'
'gliosis' means excessive 'glial cells'
'glial cells' are cells in nervous system that provide support and nutrition, maintain homeostasis, and participate in signal transmission (+ info
HOW much pet scan is useful for my son ?
MY SON WHO IS 4 YEARS 6 MONTHS OLD NOW WEARING COCHLEAR IMPLANT IN THE RIGHT EAR AND DIGITAL HEARING AIDS IN THE LEFT EAR . IN HIS MRI BEFORE THE SURGERY GLIOSIS IN THE RIGHT BASAL GANGLIA EXTENDING SUPERIORLY INTO THE SUBCORTICAL WHITE MATTER . HE IS HAVING DYSTONIA IN THE LEFT HAND AND SLIGHT WALKING IS AFFECTED FOR THIS PHYSIOTHERAPY AND TIDOMET LS110 3 TIMES A DAY IS CONTINIUD . I'VE HEARD ABOUT THE PET SCAN HOW MUCH IT COULD BE BENEFICIAL FOR MY SON AND SHALL I GO FOR THAT TO KNOW HOW MUCH IS THE DAMAGE HEALED OR LESION IS THERE ?
he has gliosis in the basal gangalia
projecting superiorly into the white matter superiorly .SPECT SCAN OR PER SCAN .
MRI CAN NOT BE DONE B/C HE IS WEARING COCHLEAR IMPLANT .
In a nutshell, PET scan wouldn't be very useful in this situation. It is used in the brain to help people who have memory disorders, tumours or seizures which may need surgery. I would have thought if prior to surgery he was given an MRI, the best modality would be to re MRI and compare the 2 sets of scans, ideally on the same MRI machine. Does your son have MS? (+ info
how much useful is spect scan for children of age 4-5 year?
a 4 yr 6 months old child is having dystonia and wearing cochlear implant.How much spect scan or pet scan can be beneficial for him,if gliosis in the right basal gangalia projecting superiorly in to the sub cortical white matter.please advice.
Consult your doctor for this one. I don't think anyone will be able to help you without having a lot more detailed history about your son. If there is something wrong in his brain, those scans would be extremely beneficial as they could catch the problem early rather than waiting for additional symptoms to appear.
Hope this helps! =) (+ info
What does this mean in laymans terms? (results of MRI of brain)?
There is a focus of increased signal intensity on the T2 weighted images within the right occipital periventricular white matter. This is nonspecific in appearance and could be due to ischemic change from small vessel disease, demyelination, or nonspecific gliosis.
There are no other areas of abnoral signal intensity identified. No cortical infarctions are identified or acute subcortical infarcts.
The ventricles & cortical sulci are normal in size and configuration.
There are no mass lesions seen or areas of abnormal enhancement.
Nonspecific white matter abnormality in the right occipital periventricular white matter.
It is important that you ask this question to a doctor. My impression is that there is some focus spot there but they don't know what the cause is. You may want to ask your doctor:
1. How common is it to have these lesions in the occiptal white matter?
2. Do I need to have a second scan in the future to see if it has gotten worse?
3. Will I go blind from this? What is the chance that it will lead to any complications? (sight / memory function / etc) (+ info
My recent brain MRI shows lacunar infarcts in the periventricular white matter / microvascular gli angiopathic
white matter gliosis. Was told by my neurosurgeon, it was not his specialty, to see my neurologist to follow, shouldnt he know about this problem as well. Plus was told I've had several minor strokes already, before this I had 2 tumors in my brain, my mother died from a brain aneurysm, what do you advise?
Follow up with a neurologist. They specialize in this matter. (+ info
Need help with MRI findings?
-Encephalomalacia and gliosis are noticed in the right cerebellar peduncle. Hemosiderin is also demonstrated in the right cerebellar peduncle
(Had hemorrhagic stroke and surgery to remove hemangioma at intersection of right cerebellum, medulla and pons in March, 2005 and never fully recovered)
What does the MRI findings mean?
Encephalomalacia means softening of brain tissue, usually caused by vascular insufficiency or degenerative changes. (Also called cerebromalacia.) It is a term used to describe a degenerative disorder in the brain - due (most likely) to the hemorrhage that caused your stroke.
Hemosiderin is an abnormal microscopic pigment found in the human body. Hemosiderin often forms after bleeding (hemorrhage) into an organ. When blood leaves a ruptured blood vessel, the cell dies and the hemoglobin of the red blood cells is released into the extracellular space. White blood cells called macrophages engulf or distruct the hemoglobin to degrade it, producing hemosiderin. (+ info
my son has cerebral cortical atrophy?
