摘　　要：目的探讨恶性胶质母细胞瘤影像学特征及其与病理之间的关系。方法回顾分析经手术病理证实的11例胶质母细胞瘤影像学表现,并与10例Ⅱ级星形胶质细胞瘤影像学表现对照。结果恶性胶质母细胞瘤占位效应11例,信号不均匀9例,瘤内血管8例,5例出血,不均匀明显强化9例;Ⅱ级星形细胞瘤占位效应3例,较轻,信号均匀9例,瘤内血管2例,无出血,轻度增强8例,其中均匀7例,欠均匀1例。恶性胶质母细胞瘤与Ⅱ级星形胶质细胞瘤影像学表现具有差异性,有统计学意义(P<0.05)。结论恶性胶质母细胞瘤具有一定的影像学特征,瘤内血管及出血坏死对诊断有帮助。Objective To investigate the relationship between the imaging findings and pathological grading of Ⅳ grade of the brain astroglioma(malignant glioblastomas).Methods The imaging findings of 11 cases with malignant glioblastomas were retrospectively reviewed in comparison with operation and pathology. Results In malignant glioblastomas, the tumor showed heterogeneous signal intensity,marked mass effect and edema.The vessels and hemorrhage within tumor were demonstrated respectively.The tumor was enhanced stro...
