Tumors of the Cranial Nerves

This chapter provides a detailed exploration of cranial nerve tumors. It covers the surgical anatomy of the cerebellopontine angle (CPA) and a range of tumor types, including vestibular schwannoma, trigeminal schwannoma, facial nerve schwannoma, optic nerve glioma, and chiasmal hypothalamic gliomas. It offers insights into their definition, epidemiology, pathology, molecular genetics, etiology, and clinical presentation. It further addresses staging and classification, diagnostic procedures, and various treatment options and considerations. The critical aspects of recurrence, follow-up, and prognosis are also discussed. This chapter serves to facilitate a well-structured approach to understanding and managing these tumors in the field of surgical neuro-oncology.
