The Oxford Textbook of Neurohaematology is a single source of knowledge on the diverse neurological conditions associated with malignant and classical haematological diseases. The book covers the full range of haematological diseases, both malignant and classical, that impact the central, peripheral, and autonomic nervous systems. The book is divided into three sections. In the first section, neurological conditions associated with malignant haematological diseases are presented. This section begins with chapters on primary haematological malignancies of the nervous system including primary central nervous system lymphomas, vitreoretinal lymphoma, and other rare primary malignancies such as Hodgkin disease and lymphoproliferative disorders. Next, a chapter on histiocytic tumours of the central nervous system presents the neurological conditions associated with the Langerhans and non-Langerhans histiocytoses. This is followed by chapters covering the neurological complications of systemic myeloid and lymphoid malignancies. The second section of the book covers neurological complications of the treatments used in the management of haematological malignancies such as chemotherapy, radiation, and immunotherapy including chimeric antigen receptor T cells. The third and final section of the book features chapters on the neurological complications associated with classical haematological diseases including disorders of red blood cells (e.g., sickle cell anaemia), disorders of platelets and coagulation (e.g., immune thrombocytopenia), and disorders of white blood cells (e.g., hyperviscosity syndrome). Edited by leading authorities in the field, this book will serve as a useful resource for neurologists, haematologists, and oncologists, as well as for subspecialists and allied health professionals involved in the management of haematological diseases and their neurological manifestations.
