A ganglioglioma is low-grade tumor of mixed cell type. This type of tumor contains properties of both glial cells (responsible for providing the structural support of the central nervous system) and neuronal cells (the functioning component of the central nervous system). These tumors are rare. They occur most commonly in the cerebrum (the largest and upper most section of the brain), but may occur in any part of the brain and spinal cord. These tumors may rarely undergo transformation into a higher grade, more malignant tumor.
