The authors discuss all the advantages offered by stereotaxic investigations in cases of cerebral tumour: three dimensional analysis of the different vascular pedicles, precise identification of the structures in which the tumours enter into relation with certain cortical loops, early demonstration of the smallest pathological displacements, histological diagnosis of space occupying processes, elaboration of a detailed operative strategy, and radiological check ups of all operations under similar conditions. They emphasize the need for several perfected radiological techniques: the use of craniography with an isocentric chair, film changers with brightness amplifiers incorporated, a fixed tube at five metres in a room that also houses stereo electroencephalography equipment. The authors' experience is based on about one hundred tumours of different kinds and of varied topography. The use of stereotaxic methods is illustrated with reference to an astrocytoma of Rolando's region, a cystic spongioblastoma of the central grey nuclei, an epidermoid cyst of the vermis of the cerebellum, a pinealoma, and a non communicating cyst of the septum. The authors present a double electronic system that makes it possible to use Talairach's proportional grid. Finally, they explain the application of their research to the recognition of information systems which would make it possible, on the basis of numerical information, to compare experimental anatomical models.
