Resection of a Gliosarcoma Using Awake Language Mapping Ressecção de um Gliossarcoma com Cirurgia Acordada para Mapeamento da Linguagem

Abstract

Surgical resection plays a central role in the management of high grade gliomas, including gliosarcomas. Surgery must be performed knowing the functional neuroanatomy and its relation to the tumor, in order to diminish the surgical morbidity.
We report the case of a 66-year-old patient with language disturbances due to an intra-axial mass lesion located in the left frontal-opercular and insular region. The resection was performed using awake language and motor mapping. It was a total resection with no post-surgical new permanent neurological deficit.
Intraoperative cortical-subcortical stimulation in the awake patient represents a safer approach to high grade glioma resection preserving function, and thus, optimizing quality of life.
