【摘要】 目的:对耳源性肥厚性硬脑膜炎(HCP)的CT和磁共振成像特点进行总结分析。方法:回顾性分析我院2006年至今临床证实的耳源性脑膜炎患者20例,所有患者均行CT和磁共振平扫及增强,比较两组的效果,并且进行对比分析。结果:CT可见值70-110Hu,内见点状钙质样密度,与黄韧带界限不清,中后颅底硬脑膜及小脑幕弥漫增厚并明显强化,MRI结果发现12例有单侧颞叶脑沟消失,6例均未见脑白质水肿信号,小脑幕强化可见"夹心饼"征,中耳乳突内呈峰窝状等或略长T1长T2信号,增强强化明显。结论:耳源性HCP的磁共振表现具有一定的特异性,而CT的灵敏度更高,所以两者结合使用能够清楚显示病灶、病变范围以及临近脑实质是否受累。更多还原

【Abstract】 Objective:to hypertrophic hard otogenic meningitis(HCP) CT and mri(magnetic resonance imaging) characteristics analysis.Methods:retrospective analysis since 2006 clinical prove otogenic meningitis patients 20 cases,all patients were performed CT and mri flat and enhance Saul,compared with two groups of effect,and comparison analysis;Results:the CT 70-110 that eigenstate Hu,inside the see pointlike calcium kind density,and yellow ligament boundary is not clear,in the skull base dural and cerebellum thickening and obviously diffuse of strengthening,MRI found that 12 patients with unilateral temporal lobe brain ditch disappear,6 cases of all did not see brain edema signal white matter,of strengthening the cerebellum visible "Sandwich Biscuit " levy,dash forward a peak in the middle ear shape or slightly long nest T1 long T2 signal,enhance obviously strengthened.Conclusion:The ear source sex of magnetic resonance HCP has certain specific performance,and the sensitivity of CT higher,so both use can be clearly showed lesions,and adjacent brain disease extent essence is affected.更多还原
