What The Difference Between Schwannoma And Meningioma
They are diff. Tumors: Schwannoma - a neoplasm originating from schwann cells (of the myelin sheath) of peripheral or sympathetic neurons, or from various cranial nerves, particularly the eighth cranial nerve; schwannomas include neurofibromas and neurilemomas. A meningioma is a tumor that arises from the meninges — the membranes that surround your brain.See 2 more doctor answers
Brain epidermoid, is it the same as a meningioma tumor the difference between the two 3cm brain stem / 8cm front lobe?
Different tumors: A brain epidermoid is a different tumor than a meningioma. That is, the pathology or cell type is distinctly different. These usually are different on imaging studies also. From your question, it seems that you are describing an epidermoid adjacent to the brain stem and a meningioma in the frontal lobe. This is consistent with the different tendencies these two tumors have to localize.See 1 more doctor answer
Have myasthenia gravis & meningiomas! Dr said advise if I have any weakness or symptoms of tumor. HOW would/could I tell the difference being Have MG?
Hard but possible: Agree it can be difficult. Important: where are the tumors? Their location in the brain can tell where you may feel weakness or sensory deficits. MG weakness is often after activity although not always and is multifocal where weakness from tumor is usually more focal. Other symptoms from tumor can be seizures or "spasms" which are not true weakness and not regularly seen with MG.
Not known: The cause for most tumors in humans are not known or obvious. It is simply an error of cell growth and cell division which leads to excess of cell production which results in formation of abnormal growths/tumors.See 1 more doctor answer
No: Most meningioma patients have no symptoms. A few will have headaches and possibly seizures if the meningioma is large enough. They are often present for many years without difficulty and can be watched.
Tumor growth: These are tumors that arise from the lining outside the brain. They are almost always benign although some studies say up to 10% can become malignant. They start early and grow- some a little, some a lot. They are found frequently in older people without needing any treatment. Your baby may have one but unless it is large, watching it is best.
Not indicative: Palinopsia, a visual disturbance marked by afterimages after the original image is perceived, is not specific for meningioma and does not indicate "stage", grade or duration. It may be secondary to nontumor sources such as strokes, medications, ms epilepsy, etc.See 1 more doctor answer
They are benign: Meningiomas are mostly benign tumors of the meninges (membrane that covers the brain surface). The tumor can be easily removed in nearly all cases. So get your surgery done and hopefully you will not have a problem again. Sometimes radiotherapy is recommended after surgery in case there is incomplete resection of the tumor.
Meningiomas: A complex question as complications are related to location of the tumor, size of the tumor, and surgical accessibility - all of these queries should discussed with the surgeon considering the surgeon.
Unlikely: Not uncommonly neurocysticercosis has multiple abnormalities on mri. Can be mistaken with pituitary tumors because they can cause endocrine changes. There are several things in the differential diagnosis. CSF analysis is important as long as there is not a lot of edema on mri. Hope this helps.See 1 more doctor answer
A microscope.: Meningiomas have a very characteristic appearance on brain scans. If they are surgically removed, a pathologist will look at the tissue under a microscope to make the final diagnosis. Sometimes they don't require removal.
Mucoperiosteal thickening (applying to post meningioma resection) what does this mean and affects?
Why is there still a decently high 5 year mortality rate asscociated with meningioma even it fully removed? I don't quite understand
