Brainstem gliomas constitute 10-20% of all pediatric CNS tumors. Brain stem astrocytomas are usually fibrillary. Based on their appearance they can be focal, exophytic, cervico-medullary and focal tectal gliomas. Malignant gliomas are characterized by the infiltrative growth of malignant cells and they grow along the white matter tracts. Rarely, an extension of a tumor may be seen along the cranial nerve, simulating a nerve sheath tumor. We report a case of a brainstem glioma in a 5 – year old female patient, extending along left seventh-eighth cranial nerves into the left internal auditory canal.
