Diagnostic criteria, pathological features and associated genetic alterations are described in a strictly disease-oriented manner. Sections on more than 70 neoplasms and their variants include ICD-O codes, incidence, age and sex distribution, location, clinical signs and symptoms, pathology, genetics and predictive factors. New disease entities include the chordoid glioma of the third ventricle and the cerebellar liponeurocytoma. Inherited tumor syndromes involving the nervous system are dealt with in a separate chapter, combining diagnostic criteria, pathology and genetics.
