Pathology
Glioblastoma
Glioblastoma is the most common malignant primary brain tumour. Under the 2021 WHO classification the term is reserved for IDH-wildtype diffuse astrocytic tumours (CNS WHO grade 4); IDH-mutant grade 4 tumours are now called astrocytoma, IDH-mutant, grade 4. Imaging typically shows a rim-enhancing, necrotic mass. Tumour cells extend well beyond the enhancing margin, and the prognosis remains poor despite therapy.
Standard care is maximal safe resection — often with fluorescence guidance and functional mapping — followed by concurrent chemoradiation with temozolomide.
