摘要
目的:提高MRI对颅内肿瘤的诊断准确率。方法:手术和病理证实的疑难病例13例,回顾性分析肿瘤的MRI图像特征。结果:13例中脑转移瘤7例,胶质母细胞瘤、胚胎发育障碍型神经上皮瘤、颅内淋巴瘤、海绵状血管瘤、丘脑脑膜瘤及蝶窦黏液表皮样癌各1例。结论:要提高MRI对颅内肿瘤的定性诊断准确率,需要了解转移瘤的发生部位及MRI表现的多样性,同时加强对少见病的认识。
Objective：To improve the accuracy of MRI diagnosis of brain tumors.Methods：MR imaging manifestations of 13 difficult cases were studied, who were confirmed by surgery and pathology. Results：The 13 cases included metastasis （7 cases） and glioblastoma, dysembryoplastic neuroepithelial tumor, intracranial lymphoma, carcinoma, thalamus meningioma and sphenoid sinus mucoepidermoid carcinoma case for each respectively. Conclusion：To improve the accuracy of MRI＇s diagnosis of brain tumors, both awareness of varieties of metastasis positions and MR imaging manifestations about brain metastasis and uncommon ttunors were necesary.
