KNOW ABOUT OLIGODENDROGLIOMA RADIOLOGY

Definition

Oligodendrogliomas are a unprecedented shape of brain tumors. The mind is made up of many supporting cells that are known as glial cells. Any tumor of these glial cells is known as a glioma. Oligodendrogliomas are tumors that arise from a type of glial cell known as oligodendrocytes. These cells are the specialised cells of the brain that produce the fatty overlaying of nerve cells (myelin).

 

 

 

 

Description

Oligodendrogliomas can grow in one of a kind components of the mind, but they’re maximum generally located in the frontal or temporal lobes of the cerebrum. The frontal lobes are answerable for cognitive idea approaches (knowing, questioning, getting to know, and judging). The temporal lobes are responsible for coordination, speech, hearing, reminiscence, and attention of time. There are  styles of oligodendroglioma: the welldifferentiated tumor, which grows tremendously slowly and in a defined shape; and, the anaplastic oligodendroglioma, which grows tons more unexpectedly and does not have a nicely-defined form. Anaplastic oligodendrogliomas are an awful lot less common than well-differentiated oligodendrogliomas. More not unusual than either form of natural oligodendroglioma is the mixed glioma, or oligoastrocytoma. These mixed gliomas are a aggregate of oligodendroglioma and astrocytoma. An astrocytoma is a tumor that arises from the astrocytes, specialised cells within the mind that modify the chemical environment of the brain and help to shape the blood–mind barrier. Oligodendrogliomas and mixed gliomas account for about 4 to five% of all primary brain tumors and 10% of all gliomas. A number one brain tumor is a tumor that begins within the brain, rather than a secondary (or metastatic) mind tumor, which originates in another organ and spreads (metastasizes) to the mind.
