Intraoperative Cortical Sensorimotor Mapping During Glioma Resection Monitored With Drum Playing During Awake Craniotomy: A Case Report.

ABSTRACT: Background: Tumors infiltrating the precentral gyrus remain a unique operative challenge. In this study, we explored a novel approach for awake craniotomy involving a patient playing a drum pad during resection of low-grade glioma, with the use of preoperative navigated transcranial magnetic stimulation (nTMS)-generated diffusion tensor imaging (DTI) and high-density real-time electrocorticography (ECoG). Observation: A 36-year-old left-handed male with a low-grade glioma in the left hemisphere hand knob region had a grand mal seizure. We combined preoperative nTMS-DTI with intraoperative passive functional mapping using high-density real-time ECoG. During an awake craniotomy, the patient played a drum pad while we assessed somatosensory-evoked potentials (SSEPs) using a 64-c
