脑胶质瘤的CT诊断

目的：进一步研究常见胶质瘤的CT表现特征，提高诊断水平。方法：回顾性分析和总结34例胶质瘤的CT表现特征，结果：34例胶质瘤中，星形细胞瘤24例，少枝胶质细胞瘤5例，室管膜瘤2例，髓母细胞瘤3例，成人多于儿童，幕上多于幕下，不同类型的胶质瘤有特殊的发病部位及典型的CT特征。结论：全面的CT影像学认识与病人年龄，病变部位相结合，能提高脑胶质瘤的诊断准确率。

CT Diagnosis of Brain Glioma

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.
