Diffuse astrocytoma NOS (gemistocytic)


This case demonstrates fairly typical (pathologically-proven) features of a gemistocytic astrocytoma. Although they are considered WHO grade II tumors, they have a poorer prognosis than other grade II astrocytomas. 

Note: IDH mutation status is not provided in this case and according to the 2016 WHO classification of CNS tumors, this tumor would, therefore, be designated as a gemistocytic astrocytoma NOS.
