【摘要】 目的　评估MR和CT对颅内硬膜外积脓的诊断价值。方法　对 4例颅内硬膜外积脓的CT和MR表现进行分析。结果　 2例额部 ;1例额顶部 ;1例后颅窝。 4例颅内硬膜外积脓处硬膜明显增厚 ,均匀强化 ,局部骨板侵蚀破坏变薄或增生。结论　CT和MR可以清楚显示颅内硬膜外积脓的形态学和病理学改变 ,因此CT和MR是诊断颅内硬膜外积脓最有价值的方法更多还原

【Abstract】 Objective To evaluate CT and MRI for the diagnosis of cranial extradural empyema.Methods The imaging features in 4 patients with cranial extradural empyema were analyzed.Results 2 cases in frontal,1 case in frontalparietal,1 case in posterier cranial fossa,in this series of 4 cranial extradural empyemas was found homogenous enhancement of dural,and thickened meninges surrounding the empyema.In the series of 1 case show bony thickening and thin.Conclusion The CT and MR of cranial extradural empyema can well demonstrate the morphological and pathological evidence of ivolved menings.Therefore,CT and MR is the most diagnostic value in cranial extradural empyema.更多还原
