What is an intra-axial mass?
Intra-axial is a term that denotes lesions that are within the brain parenchyma, in contrast to extra-axial, which describes lesions outside the brain, and intraventricular, which denotes lesions within the ventricular system.
What does Extraaxial mean?
Extra-axial is a descriptive term to denote lesions that are external to the brain parenchyma, in contrast to intra-axial which describes lesions within the brain substance.
What does mass effect mean on CT scan?
The local pressure from a tumor or bleeding (hematoma) on adjacent parts of the brain. Mass effect is diagnosed by an MRI or CT scan which shows where the mass is and what it is pushing on.
Where is the Parafalcine located?
Parafalcine meningioma is a common meningioma located in the cerebral longitudinal fissure, originating from the cerebral falx, with the third highest morbidity among all the meningiomas, accounting for approximately 11%–14% deaths, ranking only second to the cerebral convexity meningioma and parasagittal meningioma ( …
What is intra-axial and extra-axial brain tumors?
Brain tumors can be intra-axial or extra-axial. The intra-axial tumors are located within brain parenchyma and arise from the brain cells, while the extra-axial tumors are located outside brain parenchyma and arise from structures lining the brain or surrounding it.
What is a ependymoma?
An ependymoma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord. To get an accurate diagnosis, a piece of tumor tissue will be removed during surgery, if possible. A neuropathologist should then review the tumor tissue.
What is mass effect in physics?
Mass effect fields are created through the use of element zero. Element zero can increase or decrease the mass content of space-time when subjected to an electrical current via dark energy. With a positive current, mass is increased. The stronger the current, the greater the magnitude of the dark energy mass effect.
