Syringomelia is a relatively rare clinical entity in which fluid-filled cavities develop within the spinal cord. Although modern imaging technologies usually permit an accurate diagnosis at an early stage, syringomyelia remains an enigmatic condition. This reference monograph provides an up-to-date account of the present state of understanding of syringomyelia and related disorders. The editors aim to document the best clinical practice in diagnosis and treatment and to provide clear guidance on how to reduce the incidence of severe outcomes. New challenges are addressed, including the appropriate management of the increasing number of apparently idiopathic syrinx cavities that are detected. In addition, controversies in current practice and directions for future research are fully discussed. Syringomelia will be an invaluable source of information for experts in the field, specialists in various related disciplines and other interested health care professionals.
