Recurrent Brain Neoplasm

This pilot clinical trial studies how well electrocorticography works in mapping functional brain areas during surgery in patients with brain tumors. Using a larger than the standard mapping grid currently used during brain tumor surgery or a high-definition grid for electrocorticogram brain mapping may help doctors to better identify which areas of the brain are active during specific limb movement and speech during surgery in patients with brain tumors.

This study investigates the role of intraoperative shear wave elastography ultrasound (ISWEU) in identifying healthy brain and tumor tissue stiffness differences. This data may be used to guide tumor resection in future patients.
