BRAF V600D mutation in a paediatric high-grade glioma

The authors report a case of high-grade glioma with unusual pathology that has not previously been reported in glioma pathology. The 5-year-old patient presented to the emergency department with a 1-day history of a right temporal swelling on a background history of increasing nausea and vomiting for the preceding 5 months. A computed tomography brain was performed, which showed a large right-sided temporoparietal lesion. The patient underwent surgery to remove the mass and pathology confirmed anaplastic astrocytoma (WHO Grade 3). This report focuses on prognostic factors in high-grade glioma, particularly on pathological indicators, namely epidermal growth factor receptor, O6-methylguanine-DNA-methyltransferase expression and BRAF V600D mutation.
