摘要
目的:通过分析不同等级胶质瘤的超声声像图表现,探讨术中超声在胶质增生和胶质瘤鉴别诊断以及胶质瘤分级中的临床应用价值。材料和方法:对21例胶质增生及胶质瘤患者的术中超声声像图进行回顾性分析,比较胶质增生及不同等级胶质瘤的超声声像图特征。结果:2例胶质增生,6例低级别胶质瘤,4例间变性胶质瘤和9例胶质母细胞瘤的声像图各具特征。尤其是高级别胶质瘤内的坏死液化发生率达到了53.8％(7/13),而胶质增生和低级别胶质瘤中均未见坏死液化灶,两者差异存在显著性(P<0.05)。结论:术中超声在诊断胶质增生及对胶质瘤分级中具有一定的应用价值。
Purpose:To evaluate the usefulness of intraoperative ultrasound in grading the malignancy of glioma.Materials and Methods: Using grey - scale US analysising the characteristics of 21 gliosis and different grade gliomas.Results: There is different characteristics of gliosis, low grade gliomas, anaplastic gliomas and glioblastoma can be shown in imaging. There is 53.8%(7/13)liquefaction necrosis in high grade gliomas, but no in low grade gliomas (P < 0.05) .Conclusion: Ultrasound is valuable certainly for evaluating malignancy of gliomas.
