Twentythree of these cases were collected which had certain common features. Grossly they tended to be cystic and compressed adjacent brain. Microscopically they were malignant-appearing and demonstrated a prominent mesenchymal component. Sixteen cases showed focal evidence of glial and/or neuronal-appearing differentiation. It is suggested that the mesenchyme is also an aspect of tumor differentiation. The biologic behavior of these tumors was malignant, with an average duration of 18 months from onset of symptoms to death.

T h e tumors were divided into Grades I a n d 11, and into "compact" types where representative tumor types were located i n separate areas, and "diffuse" types where representative tumor cells were intermingled.
