Low grade gliomas (LGG) are well-differentiated (not anaplastic). However, they can recur and increase in grade overtime. Scroll down for information about LGG prognosis.
Types of low grade glioma
Low grade astrocytomas and oligodendrogliomas usually develop only where they originated and grow slowly over a period of time. These tumours can arise anywhere in the brain or spinal cord. The most common areas for them to occur are the cerebral hemispheres (frontal, parietal, temporal lobes) and the cerebellum.
The different types of low grade glioma commonly include astrocytomas or oligodendrogiomas.
They can spread (disseminate) to other areas of the brain or spinal cord in the cerebrospinal fluid, although this is rare. Tumours can be solid or part cystic (fluid filled).
