The 28th annual conference of the German Society for Neurosurgery was held in Cologne, West Germany, from the 18th to the 21st of September 1977. The conference dealt with problems concerning craniocerebral injuries and space-occupying processes in the posterior cranial fossa as well as general topics on clinical practice and research with special attention paid to the work of younger neurosurgeons. This volume is a presentation of the conference results. Within the scope of the general topics, special interest was directed toward the que­ stion of the current status of cytostatic treatment for brain tumors. In addition to experimental investigations, the results concerning cerebral tumors and medulloblas­ tomas are reported. Cerebellar tumors represent two further focal points: 1. From the diagnostic viewpoint, specific results from computerized tomography are discussed, especially with regard to the more extensive anatomic difficulties involved in the posterior cranial fossa. 2. With emphasis on cerebellar processes, the results of long-term measurements of intracranial pressure during the postoperative follow-up period are reported.
