title: [The histologic extemporaneous examination in neurosurgery. About 1000 cases (author's transl)].
abstract: One thousand extemporaneous examinations performed in the neurosurgical department over a nine years period have been reviewed. The purpose of these examinations was to deal with the following points: - presence or absence of a tumor, - primary or secondary nature of this tumor, - appreciation of the malignancy degree. It seems possible to draw the following conclusions: The frequency of false diagnoses was not significantly different from the one observed in out precedent series. On the other hand, with experience, the number of "approximate diagnoses" was strongly reduced. Some special diagnosis problems were discussed. The importance of the clinical data in establishing a correct diagnosis was emphasized.
