[Metastasis of visceral tumors in intracranial tumors. Apropos of a metastasis of a lung cancer in an intracranial meningioma].

In a 52 years old man a backward epilepsy revealed a left fronto parietal tumor. The histopathological study shows that it is a meningial tumor composed around by meningocytic proliferation with a metastasis of lung cancer in the middle. This fact was proved only two months after neurosurgical intervention. Thirty three cases of cancer with metastasis in an intracranial primitive tumor have been collected in the literature. The authors study the clinical aspects and etiopathogenic hypothesis of this surprising anatomopathological fact.
