Knowledge about the etiology, diagnosis, and treatment concepts of neuro-oncologic diseases is rapidly growing. This turnover of knowledge makes it difficult for physicians engaged in treatment to keep up to date with current therapies. This book aims to close the gap and explores several innovative concepts. As a comprehensive text on neuro-oncology, its chapters are interconnected, but at the same time, some chapters or subdivisions are so thoroughly assembled that the whole volume gives the impression of several books combined into one. Neuropathology is treated in an extensive and clearly structured section. The interested reader will find for each tumor entity the latest well-referenced consensus regarding histologic and molecular pathology. Through this "book-in-the-book" concept, information on neuropathology is readily available in a concise form and without overload.
