【摘要】 目的探讨不典型脑膜瘤的CT诊断。方法18例不典型脑膜瘤均行CT平扫,17例行CT增强扫描,均经手术病理证实。结果混杂密度的脑膜瘤11例,囊性脑膜瘤4例,完全强化性脑膜瘤3例。结论确定瘤体位于脑外是提高不典型脑膜瘤CT诊断准确性的关键,但也有极少数脑膜瘤表现不典型,在鉴别诊断时应引起注意。更多还原

【Abstract】 Objective To explore CT diagnosis of atypical meningioma .Methods 18 cases of atypical meningioma were undergone MR plan scans, among them,17 cases were examined by CT contrast scans. All cases were proved by operation and pathology.Results The tumors appeared as mixed density in 11 cases,cystic in 4 cases,complete enhancement in 3 cases.Conclusion The tumors to be comfirmed at external cerebra is the key in diagnosing atypical meningioma exactly by CT.Atypical manifestations can be seen in a few meningiomas,therefore, it is significant in differential diagnosis of meningioma.更多还原
