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. ...Read more
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 as well. 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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
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. ...Read more
Mucoperiosteal thickening (applying to post meningioma resection) what does this mean and affects?
Meningioma: Discuss with the neurosurgeon. Mucoperiosteal thickening is usually due to infection or inflammation of the nasal sinuses. Is this a separate issue or does the meningioma extend into the sinuses? Did removal of the tumor lead to a skull defect and drainage of cerebrospinal fluid. ...Read more
Why is there still a decently high 5 year mortality rate asscociated with meningioma even it fully removed? I don't quite understand
What do you advise if I am 35 years old women, what do you advise if I am single, i m oprated in 18th january2014lefrpt CP angle meningioma. After surgery?
Continued follow up: Meningiomas are the second most common tumor in the cerebellar pontine angle. The vast majority of these tumors are benign. It is common for these tumors to recur, so continued follow up is essential. Most patients live a normal life after surgery, assuming that there were no complications with surgery. ...Read more
No: No. Meningiomas rarely become cancerous and tend to be found incidently at autopsy. Rarely, really big ones can cause increased intracranial pressure and have to be surgically removed. They due tend to cause seizures due to irritation on the surface of the brain. ...Read more
Yes: All abnormal growths in the brain are serious. A meningioma is brain tumor that can vary from very mild to very severe. Some are very slow growing and depending on the patient's age and risks for surgery "might" not be removed. Most are removed, simply because the earlier one can be removed the less the chance it could grow so big as to kill someone. That is too simplistic an answer. ...Read more
2: The majority of meningiomas are classified at grade 1 or benign by the world health organization criteria. If there are features of more aggressive nature on the pathology slides it can be classified as a grd 2 or atypical. The carry a higher incidence of recurrence. ...Read more
Imaging studies: The only way to truly diagnose a meningioma is by imaging studies, of which an MRI with contrast is the most reliable. The most important thing to realize, however, is that tissue diagnosis (by way of a biopsy or resection) is the only 100% reliable way to diagnose tumor types and also helps to determine their aggressiveness (grade). ...Read more
