Central nervous system tumors contain neoplastic and nonneoplastic lesions. Incidence of brain tumors has increased in all age groups in recent 20 years. Developments of medical devices such as CT scan, MRI and varying of classification are important causes of this raising. The present study evaluates epidemiology of brain tumors from 1997 to 2001 in Kerman. In a cross sectional study all files of neurosurgery department, in Kerman Bahonar Hospital and from 1997 to 2001, were inquired. Variables such as age, sex and histological considerations were evaluated. A total of 338 tumors were studied. The most common tumor was glial (35%), and meningioma was the second common tumor (26.3%). The other tumors were anaplastic astrocytoma, astrocytoma, pituitary adenoma, aucostic neorinoma, medulloblastoma, ependymoma, choroid plexus carcinoma, craniopharyngioma, lymphoma, sarcoma and anaplastic ependymoma. There was statistical significant difference between tumors and sex and age (p<0.05). Age and sex distribution of brain tumors is compatible with other studies in many countries. These findings suggest that prevalence of brain tumors in Kerman has increased in recent years because of diagnostic methods have improved and other medical devices are available.
