目的:探讨侵袭型胶质瘤的MRI表现,提高对本病的认识,利于诊断和鉴别诊断。方法:对48例经手术和病理证实的侵及颅内多部位的胶质瘤MRI表现进行分析。结果:侵袭型胶质瘤通常侵犯颅内三个以上部位,MRI信号为明显长T1长T2信号,其内常合并坏死、囊变及瘤结节形成,且伴有不同程度的占位效应及造影剂强化效应。MRI可清楚显示其地形学或局部解剖学情况。结论:侵袭型胶质瘤是胶质瘤的一个特殊临床类型,MRI对本病的诊断具有指导性意义
Objective: To investigate the MRI findings of invasive glioma and to improve the understanding of this disease, which will benefit the diagnosis and differential diagnosis. Methods: MRI findings of gliomas in 48 cases confirmed by surgery and pathology were analyzed. Results: Invasive glioma usually infiltrated more than three sites in the brain and the MRI signal was obviously long T1 long T2 signal, which often accompanied necrosis, cystic change and tumor nodule formation, accompanied by different degrees of mass effect and Contrast enhancer effect. MRI can clearly show its topography or local anatomy. Conclusion: Invasive glioma is a special type of glioma, MRI has the guiding significance for the diagnosis of the disease
