[Glioma in a patient with multiple sclerosis]. / Gliome chez une patiente atteinte de sclérose en plaques.

The simultaneous occurrence of multiple sclerosis and a primary brain neoplasm is exceptional: only 32 cases have been reported in the literature. We report the case of a 30-year-old woman with multiple sclerosis proven for 10 years who developed a grade II astrocytoma revealed by MRI. At the pathology examination, there was no cellular continuity with areas of demyelinized white matter. Unlike the hypothesis put forward in certain publications describing this association that argue for an induction link between these two entities, our case did not demonstrate any spatial or temporal relationship suggestive a common cause.
