Neuroanesthesia management of neurosurgery of brain stem tumor requiring neurophysiology monitoring in an iMRI OT setting

Abstract

This report describes a rare case of ventrally exophytic pontine glioma describing operative and neuroanesthesia management. The combination of intraoperative neuromonitoring was used. It constituted: Brain stem evoked responses/potentials, Motor EP: recording from cranial nerve supplied muscle, and Sensory EP: Medial/tibial. Excision of the tumor was done with intra-operative magnatic resonance imaging (iMRI), which is considered a new modality.
