title: [Contribution of electron microscopy to the diagnosis of cerebral tumors].
abstract: The authors comment on the role of electron microscopy in the diagnosis of brain tumors. This kind of morphological investigation is essential for the differential diagnosis of undifferentiated or round cell tumors, especially on small biopsies. In addition, electron microscopy clarifies the nosology of numerous entities, such as germinomas, lymphomas, astrocytic gliomas, neuronal tumors, medulloblastomas and pinealomas. Finally numerous ultrastructural details are provided, widening our knowledge of the complex pattern of brain tumors.
