Diffuse hemispheric glioma (DHG), H3 G34 mutant was included in the 5th edition of the World Health Organization Classification of Tumors of the Central Nervous System recently published. Given the recent inclusion in the current classification and its rarity in adult patients, there are scarce data on clinical-radiological characteristics, survival, and outcome. The authors report the case of a 35-year-old female with DHG, H3 G34-mutant characteristics and outcomes with an unusual presentation, recurrence, and prolonged survival.

Methods: We extracted data from the medical records of patients age older than 18 years who were diagnosed with BC and started treatment or follow-up in private oncology institutions in Brazil between 2018 and 2021.
Article Synopsis
- The study evaluated the clinical outcomes of 37 patients with brain arteriovenous malformations (AVM) who underwent single-dose reirradiation using LINAC, analyzing various patient and treatment characteristics.
- Results showed that 55.5% of patients had angiographic occlusion post-treatment, and a significant predictor of AVM cure was a reduction in nidus volume over 50% from the first procedure.
- The findings suggest that single-dose reirradiation is safe for partially occluded AVM, but it may be ineffective if the initial dose was below 15.5 Gy or if the nidus volume reduction was less than 50% prior to reirradiation.
