,COMMENT:  ,Operating microscope was quite helpful in this; as we could use the light as well as the magnification to help us delineate the brain tumor - gliotic interface and while it was vague at sometimes we could I think clearly get a good cleavage plane in most instances so that we got a gross total removal of this very large and necrotic-looking tumor of the brain.
