Posterior Mesencephalic and Pontine Pilocytic Astrocytoma
Last Updated: September 28, 2018
This chapter describes the techniques for resection of dorsal brainstem gliomas along the superior pons and mesencephalon. For general considerations, diagnosis, evaluation, and preoperative/postoperative considerations, please refer to the chapter on the Principles of Brainstem Surgery.
Removal of gliomas located within the brainstem is risky and not commonly advised. Very focal benign gliomas, such as pilocytic astrocytomas, are an exception; the offer of surgery should be judiciously considered. Most such tumors are not operative candidates unless the tumor is cystic and the nodule is in the proximity of a safe pial surface.
