After the death of Raymond Escourolle in 1984, Françoise Gray joined Jacques Poirier for the third edition; Jean-Jacques Hauw and Romain Gherardi con- tributed to selected chapters as well. The first three editions reached the English- speaking public thanks to the friendship and translating ability of Lucien Rubinstein. Neuropathology has evolved to such an extraordinary extent since 1993, the date of publication of the third English edition, that it is no longer possible for just two or three individuals to produce a high-quality, updated new edition. For this fourth edition, therefore, Umberto De Girolami has joined us as a co-editor, and we have sought the collaborative efforts of multiple experts throughout the world to write the English language text. The compilation of a basic work designed to familiarize physicians-in-training with such a highly specialized discipline as neuropathology entails two opposing risks: in attempting to compress the maximum amount of information within the minimum space, the text is liable to become unintelligible to beginners; if, on the contrary, one tries to maintain too elementary a level, the danger is that only the obvious will be stated. In presenting to the noninitiated reader neuropathological information that some may find too simple, we have opted for the hazard of the second pitfall. Names have purposefully been avoided, with the exception of those traditionally associated with a particular disease. Discussions on the interpretation of lesions have been limited to relatively simple observations. Clinico-pathologic correlations have been reduced to essentials. Rare diseases have been glossed over or mentioned only for completeness.Despite their interest, historical data have been omitted. We have taken for granted that the reader has some familiarity with basic concepts of neuroanatomy, neurohistology, and general principles of anatomic pathology. This manual is indeed designed not for neuropathologists, or even trained neu- rologists, but for students and physicians-in-training, particularly those interested in anatomic pathology, neurology, neuroradiology and neurosurgery, who have recently joined a neuropathology laboratory hoping to become familiar with the essential topics of the pathology of the nervous system. Those who do not plan a career in ix x PREFACE neurology or neuropathology need not extend their studies much beyond the mate- rial covered herein; the others should regard this manual simply as an introduction to the textbooks and major references listed in the bibliography at the end of this text. We hope that the readers of the fourth edition of this book will grant it as favor- able a reception as that happily enjoyed by earlier editions.

Jacques Poirier, MD, PhD Francoise Gray, MD, PhD Umberto De Girolami, MD Foreword When I was learning neurology in the mid-1970s, neuroanatomy and neuropathol- ogy were the basic sciences of the field. Nearly a third of my formal neurological training was devoted to a serious study of neuropathology. I went to the autopsy room, removed the brain and spinal cord, fixed the tissue, and later examined it grossly and microscopically, ultimately generating a clinical-pathologic correlation. Aformal report of the findings was written, supervised by a senior neuropatholo- gist. These 50 personally analyzed cases formed the foundation of my entire career in clinical neurology. Through these cases I learned the anatomy of the nervous system, its reaction to disease, and the rigorous methods necessary to hone my clinical approach using the gold standard of neuropathology. At that point in my nascent career I had no knowledge of neuropathology except for the very simple principles learned in my medical school general pathology course. Thank goodness for the then newly available Manual of Basic Neu- ropathologyby Raymond Escourolle and Jacques Poirier. The original French mono- graph entitled Manuel Élémentaire de Neuropathologiehad just been translated into English by Lucien J. Rubinstein and published in 1973. It was my bible and savior. With it I was able to learn approaches and techniques to analyze my cases and unlock the enormous trove of invaluable knowledge that the cases held. To this day I fre- quently refer back to the little blue paperback book that had such an enormous impact on the way in which I approach neurological problems. In many ways neurology and neurological training have fundamentally changed. The basic sciences of neurology are now molecular genetics and cell biology. Current trainees must learn a great deal about structural and functional imaging of the nervous system as well as the details of a whole array of subspecialty subjects such as movement disorders, cancer neurology, stroke, demyelinating diseases, epilepsy, neuromuscular diseases, neuro-ophthalmology, cognitive and behavioral neurology, and pain. Thankfully, therapeutics is now a real part of neurology, so modern neurologists in training are faced with a dizzying array of complex treat- ments for nearly every category of neurologic diseases. As the complexity of clinical neurology has increased, the subject of neu- ropathology has become progressively neglected. The opportunity to spend nearly a year on the study of neuroanatomy and neuropathology is unavailable; yet the lessons that can be learned are even more important than they were in the past. A xi xii FOREWORD rigorous approach to neurologic disease, with the gold standard of modern neu- ropathology, is absolutely required for the neurologist of the future. In this context, Jacques Poirier, one of the original authors, is joined on the edi- torial team by Françoise Gray and Umberto De Girolami, together with 30 distin- guished neuropathologists from around the world to remodel, update, and expand Manual of Basic Neuropathologyfor the modern era. The reader will find the fourth edition to be just as clearly written and accessible as the earlier ones, but it now con- tains the relevant principles and advances in the fields of molecular genetics and cell biology. The old and new neuropathology are skillfully blended to enlighten the student of nervous system diseases with the basic principles and processes that underlie all of the major categories of illness. The basic principles of pathology of the central nervous system lead the book, with a survey of modern neuropathological methods at the end. New chapters on tumors, trauma, vascular diseases, and infections follow. A new, beautifully clear chapter on the important prion diseases is followed by thoroughly updated chapters on demyelinating diseases and degenerative disorders. Three new chapters on acquired metabolic disorders, hereditary metabolic disorders, and congenital mal- formations and perinatal diseases replace the single small chapter in the original work on toxic, deficiency, and metabolic diseases. Two new separate chapters on nerve and muscle neuropathology replace the single old chapter, reflecting the major changes that have occurred in this area of peripheral nervous system neuropathology. Finally, a wholly new chapter on the pituitary gland completes the book. The authors of the individual chapters are experts in their fields and write clearly and concisely. I found the new Manual of Basic Neuropathologya marvelous and welcome addi- tion to neurologic literature. I look forward to referring to this new version for many years to come. It will have an honored place on my library shelf, right next to the original little blue book that gave me such a great start so many years ago. Martin A. Samuels, MD
