脑胶质瘤与脑脓肿的CT鉴别

The CT scan of brain glinoma and abscess.

目的 探讨易混淆的脑胶质瘤与脑脓肿的CT表现及鉴别诊断。方法 分析20例脑胶质瘤(星形细胞瘤)和20例脑脓肿的CT表现。 结果 两者病灶均呈环状强化 ,胶质瘤的环状强化壁厚簿不匀 ,都在近脑中线侧较厚 ;可见壁结节 ,在环内侧及壁结节内有斑状及毛细血管纹状强化 ,这一征象具有特征 ;脑脓肿环状强化壁完整 ,厚簿均一 ,在环状强化边缘部位和相邻层面出现小结节性强化灶 ,这一征象有鉴别意义。 结论 只要掌握脑胶质瘤与脑脓肿两者的CT特征 ,诊断率高。

Objective To evaluate the CT scan of brain glinoma and abscess. Method Analysis the CT scan of 20 brain glinoma and 20 abscess. Results Both lesion show annular reinforcement. Glinoma reinforcement wall were uneven, blood capillary stria reforcement can be showed in the . wall inside and wall node. Abscess wall were intact and uniform, show nodose reinforcement in reinforcement border and adjacent lamina.Conclusion The diagnosis rate can be increased according CT scan of brain glinoma and abscess.
