Despite many advances in the field of cancer treatment, intra-cranial tumor cases still have a poor prognosis. This research has been carried out in order to describe age and sex distributions and histopathological characteristics and site of intra-cranial tumors. We studied 425 patients with intra-cranial tumor whose samples were examined in pathology center of Imam Khomeini hospital from 1991 to 1996. The commonest types of tumors in our study were glial (28%) tumors and meningioma (27.76%). The commonest sites of tumors were cortex (30.6%), hypophysis (21.89%), and cerebellum (15.3%). Among metastatic tumors of the brain, thyroid carcinoma was the most prevalent one (55.5%). The results of this study did not significantly contrast findings of other studies.
