This volume is the latest in the series Exercises in Radio- logical Diagnosis, launched by the Strasbourg School of Radio- logy. Further volumes on the facial bones, senology, and abdominal tomography are in preparation. Jean-Louis Dietemann has over a decade's experience of radiodiagnosis of the skull, and has already proven his talents as a teacher with his earlier books on the sella turcica and on carotid angiography. The present volume will assuredly be a great success and will enhance the series. Professor A.
