Since Harvey Cushing's extensive study on brain meningiomas no similar study has been conducted on spinal cord meningiomas. The high scientific value of this book is based on the careful elaboration of data from patients affected by spinal meningiomas who have been examined and operated on over the last 33 years (1962-1995) at the Neurosurgical School of the University of Florence, Italy. The main focus of this study was on the anatomic and clinical relationship that enabled early diagnosis of spinal meningiomas. More over this book emphasizes the interaction between neurology and neuroradiology in the form of "dynamic neurology". Myeloradiculographic findings are described together with those using more recent techniques such as CT and MRI.
