BRAIN TUMORS(Meningioma and Oligodendroglioma)I. PathologyA. MeningiomaII. EtiologyA. No known causeB.Uncontrolled division of meningial electric carrelsIII. SpecificsA.Affected cell - meninges (cover and protection of wittiness and spinal cord)B.Accounts for 20% of all intracranial tumorsC.Typically benignD.Between skull and intelligenceE.Compresses but does not invade brainIV. Symptoms/SignsA.HeadachesB.Stroke-like symptomsC.SeizuresD.Loss of visionE.Personality changesF.CT scans and MRIs can determine mien and exact locationV. TypesA.Convexity (curved part of the skull)B.Cavernous venous sinusC.Sphenoid wingD.Clivus and parasellar regionsE.Cerebellar (also occur)VI. TreatmentsA.Surgical removal (most common, first option)B.Regular radiationC.Stereotactic Radiosurgery (precise radiation delivered to the brain without harm to surrounding tissue/ this is used for meningiomas that ar more difficult to safely remove)VII. PrognosisA.Excellent (more than 95% survival rate)B.Minima l tangible therapy may be necessaryMy aunt just tardily had surgery to remove a benign meningioma. The surgery was a success and had she survived despite further complications, her interposition following the surgery was to be mere fleshly therapy to regain full or partial use of her left hand. I. Pathology A. OligodendrogliomaII. EtiologyA. UnknownIII. SpecificsA.Affects oligodendrocytes (responsible for myelin production, which covers nerves and allows for quick conduction of information)B.Most common in male adultsC.May be benign or malignant and spread to other parts of brain or even outsideIV. Symptoms/SignsA.HeadachesB.VomitingC.optical complicationsD.Memory lossE.Problems with coordination and speechF.Mood and personality changesG.Paralysis on one sideH.CT scans and MRIs can determine aim and exact location of tumorsV. TypesA.Frontal lobeB.Temporal lobeVI. TreatmentA.SurgeryB.RadiotherapyC.ChemotherapyVII. PrognosisA.Poor long termB.Often fatalityIn gain to current man ipulation methods for tumors (chemotherapy, radiation, surgery, and stereostatic radiosurgery), testing is organism done to determine the effects of hyperthermia, gene and viral therapy, as well as immunotherapy (vaccines) as possible treatment methods. This may be useful because most tumors are more sensitive to heat than other tissues. Of course, as with all cancers and diseases, continuous research is also being done to determine specific causes.Brain Tumors essays research papers fc BRAIN TUMORS(Meningioma and Oligodendroglioma)I.
