Management of low grade glioma (LGG), particularly with regards to the role of surgery, is not clear to most clinicians. LGG constitutes only a small subset of gliomas,the most common type of primary brain tumors. Primary brain tumors, in turn, make up two-thirds of all brain tumors, and half of all primary brain tumors are gliomas (Figure 1). As the name implies, gliomas originate from glial cells, primarily astrocytes and oligodendrocytes. They are classified , based on their cell of origin , into astrocytomas and oligodendrogliomas. Histopathological features determine the degree of biological malignancy, which is not divided into discrete categories but actually forms a biological continuum
