This video demonstrates surgical approach for the resection of a pontomedullary glioma in an adult patient. 53-year-old male with progressive dizziness, nausea, and blurred vision. MRI demonstrated an exophytic, cystic intra-axial right paramidline lesion of the pons and medulla with effacement of the 4th ventricle. Telovelar approach for open biopsy was performed. Pathology identified the lesion as glial tumor with high Ki67 and loss of H3K27me3 expression. Postoperative MRI revealed resection of the cystic cavity.
