The present study was performed on 15 patients with primary central nervous system lymphoma including 7 males (46.7%) and 8 females (53.3%). The most common clinical presentations were motor deficits (33.3%), increased intra-cranial pressure (26.7%) and seizure (20%) respectively. All cases were diffuse large B-cell lymphoma, and high grade in 13.3% of cases. In most of cases (80%), the lesion was in one of the cerebral hemispheres. The most frequent sites were the temporal and parietal lobe.

Primary central nervous system lymphoma is a rare, invasive, extra-nodal non‐Hodgkin's lymphoma. In our study, its clinicopathological feature was similar to the other studies. The mean survival rate in patients with immune-deficiency was not significantly different from patients without immune-deficiency
