Abstract: objective: To study the CT features of the common gliomas and improve the diagnostic accuracy. Method: This article analyzed retrospectively CT features of 34 patients with the brain glioma. Result: Thirty four patients included 24 cases with astrocytoma, 5 cases with oligodendrogllioma, 2 cases with ependymoma, 3 cases with medulloblastorma. Adult's morbidity was higher than child's, more lesions were observed in supratentory than in subtentory. Different type gliomas have peculiar location and typical CT features. Conclusion: The correct diagnosis of brain glioma could be established by comprehensive consideration of the CT appearance, the patient's age and the location of tumor.
