Diffuse low grade astrocytoma


Low grade infiltrative astrocytomas, also often referred to as diffuse astrocytomas, are designated as WHO II tumors of the brain. Gemistocytic astrocytoma is one histologic subtype with a poorer prognosis than other matched WHO grade tumors, and with no specific imaging features. These tumors are almost always supratentorial and usually located in the frontal lobes.
