Abstract:
Objective:To evaluate the relationship between MRI features and pathological types of intracranial meningomas.Methods:32 cases of meningoma which were proved by operation and pathology were compared with their MRI features and pathological types.Results:All of the 32 cases were single tumor,The lesions were located in frontal,parietal,and occipital regions nearby the convexity of the brain in 18 cases,at sphenoidal crest in 8 cases,at olfactory sulcus in 4 cases,and in sellar region 2 cases.MRI manifested that 13 cases had their intergral capsules,peri-tumor edema was found in 29 cases,dural“tail” sign was present in 9 cases,calcification in the tumors were found in 3 cases and vascular flow void features was seen in 5 cases,20 cases appeared homogeneous enhancement.Conclusion:It is of great value in presenting the location of meningoma with MRI.Combination of several MRI features could be used to figure out the pathological type of meningoma by a comprehensive analysis.
