[Primary meningeal and cerebral lymphoma. Study of a case with 8 years' follow-up]

A primary lymphoma involving the meninges of the frontobasal region, with focal cortical infiltration and prominent cerebral edema, was treated by surgery and radiotherapy. Eight years later the patient died of a recurrence. Morphological and immunohistochemical studies comparing the initial tumor with the recurrent lesion found similar histopathological features.
