This monograph is the second edition of a book that was first published in 1972 and is volume 8 in the excellent series, Major Problems in Clinical Pediatrics. The major new development of the intervening years was the computerized tomographic (CT) scan; a number of illustrations involving this technique have been added, as well as a specific section of text. However, the majority of neuroradiologic illustrations continue to be photographs of air studies, which is defensible in that a single picture tells a much better story than a series of blurry CT cuts. I suspect that the third edition will contain CT illustrations of much better resolution, and more of the gross neuropathology will be presented in brain slices that conform to the standard CT image. On the subject of illustrations, it can be said that the monograph is profusely illustrated with excellent quality pictures of patients, pathology, and radiology.
