There were 42 female and 68 male patients. One hundred and six cases (96.3%) were diagnosed as B-cell lymphoma. Most of the PCNSL in our study are unifocal. More than 70% of tumors were in a cerebral hemisphere and periventricular location, usually involving the corpus callosum or basal ganglia. No patients had been in immunocompromised states. Symptoms of increased intracranial pressure or changes in personality, vision, or motor function are most common. Seizures are seen in approximately 10% of patients. The number of PCNSL cases showed a gradual rise in incidence.CONCLUSION: The results of this single hospital 12-year survey of PCNSL are in agreement with data from other single institutions and regional surveys concerning clinical features. However, in contrast with the literature, most of our patients were immunocompetent. The age at diagnosis is also lower than in most reports.
