Introduction Metastatic brain cancer is the most common type of brain tumor in adults, in which 30% of cancer patients will ­develop brain tumors, with an estimated incidence of 200,000…

Introduction The most common type of primary malignant brain tumor in children is medulloblastoma, in which it accounts for approximately 25% of childhood brain tumors. , Medulloblastomas can also occur…

Introduction Brainstem surgery can be associated with significant morbidity and mortality. , This high risk of neurologic injury is owing to the fact that the brainstem has a high density…

Introduction Patients with high-grade gliomas are known to have poor ­survival. Among these patients, it is argued that butterfly ­lesions that cross the corpus callosum and involve both cerebral hemispheres…

Introduction Patients with high-grade gliomas have poor prognoses, with median survival approximately 12 months. A subset of patients with glioblastoma (GBM) have multifocal disease, whereby their lesions are separated by…

Introduction The general treatment paradigm for high-grade gliomas is maximal resection followed by adjuvant chemoradiation; however, patients who develop deficits have worsened survival independent of the extent of resection. Deep-seated…

Introduction An uncommon location for gliomas is the occipital lobe, in which the incidence ranges from 5% to 10% in several series. Patients with occipital lobe gliomas typically present with…

Introduction A relatively common location for high-grade gliomas is the temporal lobe, in which the incidence ranges from 15% to 25% in several series. Patients with temporal lobe gliomas typically…

Introduction A common location for high-grade gliomas is the temporal lobe. In most series, this number ranges from 15% to 25%. Patients with dominant-hemisphere temporal lobe gliomas most commonly present…

Introduction Surgery within the insula is associated with significant morbidity because it is adjacent to and involves critical cortical structures, white matter tracts, and cerebral vasculature. The incidence of subtotal…
