摘要
目的:分析颅底骨源性良性及瘤样病变的MRI表现并与CT和病理对照研究。方法:搜集经手术病理证实的颅底骨源性良性肿瘤及瘤样病变21例(骨巨细胞瘤2例,软骨黏液性纤维瘤4例,骨化性纤维瘤3例,骨瘤3例,骨纤维异常增殖症9例),全部行MRI检查(14例增强检查),7例CT检查。结果:绝大多数病变均有清晰的边界,T1WI呈低或等信号,T2WI高或混杂信号,增强后呈周边及不均匀强化。MR对钙化和骨质破坏的显示不如CT敏感。结论:MRI对颅底骨源性良性肿瘤及瘤样病变的诊断具有一定的价值,尤其能够进行精确的定位诊断。
Objective： To analyze the MRI performance between the skull base source bemgn tumor and lump land pathologlcat changes and check against the research with CT and the pathology. Methods：21 patients with pathologic proved, included：giant cell tumour （n = 2 ）, chondromyxoid fibroma （ n = 4）, ossifying fibroma （ n = 3）, osteoma （ n = 3 ）, Albright＇ s syndrome （ n = 9）. All patients were performed with MRI （14 cases with post-contrast MRI）, 7 patients were evaluted with CT. Results： Great majority pathological changes all contain clear boundary, on T1WI they had low-intermediate signal intensity, on T2WI they were high or mixed signal, reporting after strengthenning peripheral and asymmetries enhance. MR to calcify with the not equal to the sensitive of CT in manifestation that bone substance break. Conclusion：MRI to diagnosis between the skull base source benign tumor and lump kind pathological changes value having certainly, can proceed the accurate fixed position diagnosis particularly.
