Pilocytic Astrocytoma, Low-Grade Astrocytoma, and Other “Benign” Neuroepithelial Neoplasms

Abstract Subependymal Giant Cell Astrocytoma Pleomorphic Xanthoastrocytoma Gangliocytoma and Ganglioglioma Desmoplastic Infantile Ganglioglioma Dysembryoplastic Neuroepithelial Tumor Central Neurocytoma This chapter discusses most “benign” neuroepithelial tumors with a grade I or II biologic behavior. These tumors were classified pathologically in Table 1-2. Pilocytic astrocytoma is discussed initially and has a grade I biologic behavior, although its histological appearance may appear more aggressive.
