Gliomatosis cerebri
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,…
Right temporal low-grade glioma
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…
Left temporal low-grade glioma
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…
Parietal low-grade glioma
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…
Left insular low-grade glioma
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…
Right insular low-grade glioma
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,…
Wernicke area low-grade glioma
Introduction Lesions in close proximity to essential cortical language functions, namely the Broca and Wernicke areas, have long been considered to not be amenable to surgical resection. Unlike in strokes,…
Broca area low-grade glioma
Introduction The goal of achieving extensive resection for low-grade gliomas (LGGs) in eloquent regions is a relatively new paradigm, as many recent studies are now showing that observation and lesser…
Left perirolandic low-grade glioma
Introduction Gliomas are known to infiltrate cortical areas and white matter tracts. , In low-grade gliomas (LGGs), there can be interspersing tumor with nontumor tissue. Therefore when LGGs involve eloquent…
Right perirolandic low-grade glioma
Introduction Low-grade gliomas (LGGs) are characterized by the presence of mutations in the isocitrate dehydrogenase (IDH) gene, in which low-grade oligodendrogliomas also possess codeletion of chromosomes 1p and 19q, whereas…
