Introduction The primary modifiable risk factor for patients with high-grade gliomas is extent of resection. For patients with primary glioblastoma, the maximum residual volume threshold is 5 cm 3 ,…

Introduction Brainstem tumors are a rare subset of intrinsic tumors that occur in adults that account for less than 1% of the primary brain tumors in adults. , These tumors…

Introduction Surgery in the brainstem can be associated with significant morbidity and mortality. , This is because the brainstem has a high density of eloquent gray and white matter structures,…

Introduction The factors associated with worse outcomes for patients with high-grade gliomas include older patients, poorer neurologic function, tumors in close proximity to the subventricular zone, and decreasing extent of…

Introduction Gliomatosis cerebri is characterized by widespread infiltration of the brain in three or more lobes with bilateral involvement. Gliomatosis cerebri type 1 is when there is no ­obvious mass,…

Introduction A common location of low-grade gliomas (LGGs) is the temporal lobe, in which the number ranges from 15% to 25% in several series. Patients with temporal lobe LGGs ­typically…

Introduction A common location of low-grade gliomas (LGGs) is the temporal lobe. In most series, this number ranges from 15% to 25%. Patients with temporal lobe LGGs typically have subtle…

Introduction The parietal lobe is often considered a safe entry point for cortical and subcortical tumors because it avoids the ­somatosensory cortex anteriorly and the visual cortex posteriorly. However, there…

Introduction As with other low-grade gliomas (LGGs), the ideal management of these lesions involves extensive resection while avoiding iatrogenic deficits. More extensive resection is associated with longer overall survival, delayed…

Introduction The insula is considered the fifth lobe and is a complex structure both anatomically and functionally. Functionally, the insula is thought to play critical roles in memory, executive function,…
