title: [Spatial definition of cerebral tumors].
abstract: The spatial definition of brain tumors can be obtained by CT and angiography carried out under stereotactic conditions. A standard CT software is used to obtain stereotactic coordinates of any intracranial point. Serial stereotactic biopsies provide a precise and detailed histologic diagnosis, including grading and volume estimation. The stereotactic approach is directed at a better understanding of the relationship between the brain and the lesion. It provides a rational basis for the choice among treatment modalities. Our experience so far with a series of 401 cases is reported on.
