Whereas both H3F3A K27M and BRAF V600E have been reported as poor prognostic markers in pediatric glioma, our case, along with several other reported cases, suggests that the coexistence of these two mutations might not indicate poor prognosis.
Despite the presence of H3 K27M mutations, these cases should not be graded and treated as grade IV tumors because they have a better spontaneous outcome than classic diffuse midline H3 K27M-mutant glioma.
We report the case of a 17-year-old female with an H3F3A G34R mutated infiltrative glioma who developed painful osseous metastases to her pelvis and spine within 3 months of clinical presentation.
