The book series Advances in Neurotraumatology, edited by the Neurotraumatology Committee of the World Federation of Neurosurgical Societies, described in the preceding Volume I the traumatic extracerebral collections and in Volume II the cervico-spinal injuries. Volume III deals in depth with the biomechanical, neuropathological and clinical pictures of traumatic lesions of the brain tissue itself, the most frequent consequences of severe head injuries. Experts in the field discuss the new results of their own clinical investigations, neuroimaging and electrophysiology on the interpretation of diffuse and focal dynamic development of supra- and infratentorial cerebral contusions, lacerations and hematomas. Above all they consider the important consequences of these aspects for individual treatment and prognosis. For practical purposes the detailed discussions of each clinical chapter are summarized in instructions for the daily practice.
