NCIt definition : A low-grade (WHO grade 2) astrocytic neoplasm. It is characterized by diffuse infiltration of neighboring central nervous system structures. These lesions typically affect young adults and have a tendency for progression to anaplastic astrocytoma and glioblastoma. Based on the IDH genes mutation status, diffuse astrocytomas are classified as IDH-mutant, IDH-wildtype, and not otherwise specified.;

Alternative definition : CDISC: A malignant astrocytic neoplasm characterized by a high degree of cellular differentiation, slow growth, and diffuse infiltration of neighboring brain structures.;

Neoplastic status : Undetermined;
