RESUMO

The primary cerebral lymphoma (non Hodgkin lymphoma) is described as a tumor confined to the central nervous system. They are considered of very low frequency, less tha 1% of the primary tumors of the central nervous system. The up to date treatment is a combination of chemio and radio therapy in patients younger than sixty years old: After this age only radiotheraphy is recommended. We present two cases of primary cerebral lypmhomas, confirmed by the pathology. Both were operated and received steroids and radiotherapy. The first one received treatment in 1992: decadron and limited radiotherapy (1400 rads). He improved clinically and the lesion disappeared. In 1996 he was reoperated because of a recurrence. At this time a resection was performed. The patient received radiotherapy. A year later no recurrence has appeared. The second case was operated on april 1997. He received radiotherapy postoperatively, He developed aphasia and hemiplegia from which recovered completely. Both patients were immuno competent and their prognosis remains uncertain
