Gamma Knife Radiosurgery on Tectal Plate Gliomas

Tectal plate gliomas (TPGs) represent a subset of brainstem gliomas that are predominantly slow-growing, low-grade tumors and rarely produce neurological deficits. Viable options include biopsy and monitoring with serial neuroimaging, surgical resection, radiotherapy (either early following surgery or late on evidence of disease progression), chemotherapy, and stereotactic radiosurgery (SRS). SRS using Gamma Knife radiosurgery (GKRS) has been identified in small case series as a safe and promising approach for managing TPGs that necessitate intervention beyond mere observation.
