Abstract
Background and purpose: Brain tumors represent 10% of primary neoplasms of the central nervous systems. Great achievements have been made today using CT-Scan in diagnosis such tumors.
Methods and materials: This analytical prospective research was conducted in two hospitals in Mashad on 50 patients with primary diagnosis of brain tumors. All Ct- scans were interpreted by the same radiologist. The interpretations were compared with postoperative pathological results.
Results: Mean age of the subjects was 41.03±18.8 years, ranging from 6 to 71. Tumors were most common in the 4th, 5th and 7th decade and least common in the first and second decades of life.
Tumor prevalence in biopsy results were GBM (30%), meningioma (18%), asterocytoma (12%), metastasis and hypophyse adenoma (each 6%). Chi-square analysis revealed no significant relationship between the type of tumors and sufferer's sex.
Conclusion: The Findings indicated that CT- Scan is of high diagnostic value in diagnosing large tumors and that they are consistent with Pathological results in 68% of the cases.
