摘　　要：目的总结脑胶质瘤病的磁共振表现特点,并进行鉴别诊断分析。方法回顾性分析12例脑胶质瘤病的磁共振表现。结果病变至少累及2个脑叶,呈弥漫T1加权低信号、T2加权高信号,信号强度较均匀,少有造影剂增强。全部病例经手术或活检证实。结论MRI是诊断脑胶质瘤病的良好检查方法。Objective To characterize gliomatosis cerebri on magnetic resonance imaging （MRI） and analyze differential diagno- sis. Methods MRI studies of 12 patients with gliomatosis cerebri were reviewed. Results Tumors involved at least two lobes of the brain in all patients. Widespread invasion with hyperintensity was noted on T2-weighted MR images. No contrast enhancement oc curred. Tumors were confirmed with surgery or biopsy. Conclusion Gliomatosis cerebri is best detected with MRI.
