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.
