Intracerebral B-cell lymphoma represents less than 1% of all primary malignant tumors of the central nervous system. [6] [1] [3] Infiltration of lymphoma cells into the pons and medulla is the most frequently reported cause of CNH, accounting for half of all CNH-inducing brain tumors, despite its considerable rarity. It has been suggested that ...
Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these).
The pathway is antagonized by various factors including PTEN, [7] GSK3B, [2] and HB9. [5] In many cancers, this pathway is overactive, thus reducing apoptosis and allowing proliferation. This pathway is necessary, however, to promote growth and proliferation over differentiation of adult stem cells, neural stem cells specifically. [2]
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [ 2 ]
Altered brain structure in chemotherapy patients provides explanation for cognitive impairment. [12] Another study in 2007 investigated the differences in brain structure between two adult, monozygotic twin females. One underwent chemotherapy treatment for breast cancer, while the other did not have cancer and was not treated with chemotherapy.
John Force is out of neurological intensive care following treatment for a traumatic brain injury (TBI) he sustained in a fiery Funny Car crash, but still faces a "long and difficult" journey.
A neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex.
