The book is organized for easy reference into major clinical areas. Discussions proceed in a sequence paralleling the clinician's approach in developing the differential diagnosis, establishing the correct diagnosis, and initiating treatment. Thus, the incidence, etiology, pathophysiology, appropriate diagnostic procedures, and medical and surgical treatment options and their expected results are methodically presented for each neurosurgical problem. The Second Edition's expanded and upgraded program of illustrations includes state-of-the-art CT scans, MR images, radiographs, angiograms, ultrasound scans, intraoperative photographs, and drawings.
