Primary central nervous system lymphomas (pcnsl) are defined as the extra nodal non- hodgkin lymphomas which may typically be localized in brain,eyes,spinal cord and csf without arising from a focus site,and which are uncommon and non - hodgkin types. the prevalence of pcnsl has been reported to have increased pronouncedly for the last 15 - 30 years. the reason of this increase for the pcnsl among other primary brain tumors is considered to be associated with the improvements in the diagnostic methods. the objective of this study is to assess 9 patients who presented with pcnsl,retrospectively.
