Pituitary apoplexy is a rare and life-threatening complication that occurs in 0.6–10.5% of all patients with pituitary adenomas. Unfortunately, pituitary apoplexy is often misdiagnosed before surgery. Furthermore, in spite of all the advances in imaging techniques and therapeutic methods, its optimal management is still controversial owing to the limited individual experience and the very variable clinical course of the condition. This book provides an in-depth review of knowledge of the management of pituitary apoplexy, with an emphasis on clinical and neuroradiological findings and treatment modalities, medical and surgical. In addition, it supplies clinicians and investigators with detailed information on current evidence and considers future areas of investigation and innovative therapeutic philosophies. Both the editors and the authors are leading international authorities in the field.
