Primary lymphoma of the brain.

In this study, clinical and histopathological features of primary lymphomas of the brain have been described in eight patients. The primary nature of lymphoma in these patients was confirmed by extensive clinical as well as radiological investigations and supported by a detailed histopathological examination. Computerised tomography (CT) scan showed multiple intra-cerebral lesion in two patients and in six patients the lesion was solitary. Although primary lymphoma of the brain carries poor prognosis, it is essential that these tumours should be accurately diagnosed as well as should be distinguished from secondary tumours.
