What are symptoms of PPMS? Had a Brain and brain stem MRI - normal. I still think I have PPMS.

What are symptoms of PPMS? Had a Brain and brain stem MRI - normal. I still think I have PPMS.

See a neurologist: Primary progressive multiple sclerosis is a form of MS based on the timeline of your symptoms. In order to be diagnosed with PPMS, you must first have a diagnosis of MS by a neurologist. Secondly, you must have a clinical course that is indicative of PPMS - it can only be diagnosed over time. See a neurologist for further evaluation. http://www.nlm.nih.gov/medlineplus/multiplesclerosis.html ...Read more

Mri (Definition)

Mri or magnetic resonance imaging is one of the more recently developed imaging modalities available to physicians. It uses powerful magnets to generate images. There is no ionizing radiation which is a major advantage over many other modalities. Mri is the best imaging exam that we have for most soft tissue and joint related problems. There are radiologists ...Read more

My son has a longer than normal brain stem, had a MRI to find it - what is it called? Had a seizure - had an MRI - this is the only thing they found. It is only a couple millimeters longer.

My son has a longer than normal brain stem, had a MRI to find it - what is it called? Had a seizure - had an MRI - this is the only thing they found. It is only a couple millimeters longer.

One : One must always remember that a MRI of the brain is an extremely accurate study of the anatomy which includes the brain, sinuses, skull, and the meninges among other tissues. In my 15 years as a neurologist, I have never seen a radiology report that comments on the length of the brainstem. However, some individuals will have protrusion of the cerebellar tonsils through the bottom of the skull (foramen magnum). This is most often a normal finding. Once the cerebellar tonsils protrude > 3 mm then the term arnold chiari malformation is given. There are various types (i, ii, etc) which depend on other physical exam findings. One must keep in mind that there is a certain amount of arbitrariness when deriving the length of cerebellar tonsillar herniation as it all depends on the judgment of the interpreting radiologist who must decide where to measure the bottom of the skull.

Since this MRI was ordered as a workup for seizures, i would consider this an incidental finding since an arnold-chiari malformation should have no direct relationship to causing seizures. These are appropriate questions to ask the physician who ordered the brainscan and if they cannot answer your questions then they should confer with the interpreting radiologist for guidance and get back to you.

Good luck. ...Read more

Is a brain stem stroke diagnosable by MRI, or is it just a clinical diagnosis? I have an inkling by looking at the symptoms that I had one.

Is a brain stem stroke diagnosable by MRI, or is it just a clinical diagnosis?  I have an inkling by looking at the symptoms that I had one.

Typically yes: yes typically acute stroke will show up on MRI brain. In very rare instances strokes can be not seen (especially posterior circulation related) and the term "MRI negative stroke" is used in such a scenario. If you think you had a stroke you need to go to ED immediately to get MRI brain and close observation as some strokes can result in a dangerous brain swelling especially in young adults. ...Read more

What areas of brain does "mri brain stem w/o dye" image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?

What areas of brain does "mri brain stem w/o dye"  image or cover?Is mra included in above and does it like mra image or look for cerebral aneurysm?

Whole brain stem: The MRI would look at your entire brainstem, shown in the picture. The brainstem is the lower part of your brain that controls breathing and heartrate. An mra (magentic resonance angiogram) is not the same, and would be ordered as a separate test with dye injection. An mra looks at blood vessels for aneurysyms, obstructions, or tears, while an MRI looks for tumors, demyelination, or strokes. ...Read more

I have a mengimioa on the right side on the brain stem. Yesterday i had bad pain in my neck on the left side.. Idid a MRI stable.Could this be from t?

I have a mengimioa on the right side on the brain stem. Yesterday i had bad pain  in my neck on the left side.. Idid a MRI stable.Could this be from t?

Possible but ...: Possible but not probable. The localization and the pathway that you described correspond to sphenothalamic tract that moves pain and temperature to cerebral cortex of the opposite side. However, your MRI is stable and single episode is not an indicator on any type of neuralgia. I assume that your meningioma is under monitored observation (wait-and-see approach). ...Read more

SIR,what is mean by FAINT HYPODENSITY OF RIGHT HALF OF BRAIN STEM AND RIGHT PEREBELTAR TEDUNCLE FEEDS MRI BRAIN FOR FURTHER CHARACTERIZATION.plz reply?

Vascular Disease: I can guess you are saying hypodense lesions in right brain stem and right cerebellar peduncle. Reader is suggesting MRI of Brain to further clarify. Many such lesions are due to vascular disease but there are other reason that is why you may need MRI. If you provide actual report could give you more specific answer. ...Read more

Did I maybe have a brain-stem stroke? Took pseudoephedrine, BP shot from 110/55 to 217/117, was vomiting, dizzy, blurry vision, migraine. MRI normal.

Did I maybe have a brain-stem stroke?  Took pseudoephedrine, BP shot from 110/55 to 217/117, was vomiting, dizzy, blurry vision, migraine. MRI normal.

Adverse Effect: I think perhaps you were given a larger dose than needed or you have a hypersensitivity to this medication. Pseudoephedrine usually used just to decrease symptoms relating to a cold or flu. (Watery eyes, runny nose, stuffy head/sinuses, scratchy throat). Adverse effects of this OTC med is to raise BP, cause restlessness, tremor, insomnia, nervousness, to name a few. ...Read more

In 97/98 I was diagnosed w/prob M.S. by 3 dif. Dr.'s I had multiple symp M.R.I  done & was told I have 2 spots on brain stem, my mem/mgrns r worse, what do I do?

See below: You probably have multiple sclerosis, and you need to be taking a potent oral agent, or even tysabri (natalizumab). Get updated mri's of both neck and brain, spinal fluid if doc unsure, and compare with prior films. N.B., migraine and ms are co-morbidities, and the memory loss is a sign of increased burden of disease. Do not wait, get all of this addressed. ...Read more

How long do most people survive brain stem glioma, before it kills them?

Variable: 'brainstem glioma' as a term covers a variety of very different tumors. The classic pediatric 'brainstem glioma' is a diffuse infiltrating high grade tumor of the pons, and it is usually fatal in less than two years from diagnosis. Some children and some adults have focal brainstem tumors, more commonly of the midbrain or medulla, and these may be surgically removable and have a long survival. ...Read more

What are the different in symptoms brain stem lesion and cortex lesion with details ?

What are the different in symptoms brain stem lesion and cortex lesion with details ?

Anatomy = function: The different brain regions control different functions. At the same time, they are interconnected. A brainstem lesion can cause any number of cranial neuropathies, impaired breathing, and in some cases, death. Cortical lesions can affect muscle strength, personality, language, etc. See a neurologist for further discussion. http://www.webmd.com/brain/picture-of-the-brain ...Read more

If your on life support due 2 caerdic arrest & the brain stem is fine just the other part of brain is dead . can your brain recover & u survive . :(?

If your on life support due 2 caerdic arrest & the brain stem  is fine just  the other part of brain is dead . can your brain recover & u survive . :(?

Anoxic injury: to the cerebral hemispheres can result in so much brain swelling that the brain stem is damaged due to compression. This typically occurs 72 hours after the episode of ischemia and results in death. If one survives the consequences of cerebral edema, the resultant deficits depend on the degree of injury and recovery. No two cases are alike. Recovery can be a slow process and incomplete. ...Read more
