Abstract

Objective To assess the correlation between the MRI features of meningioma and related pathology. Methods Thirty-eight cases of meningioma confirmed by surgery and pathology were reviewed, and their MRI features of the meningioma and histological type were analyzed, including the signal appearance of the tumor, tumor-brain interface status, peritumorous edema, tail sign, and the signal uniformity after enhance.Results MRI signal features of meningioma included low SI on T_1W images, high and mixed SI on T_2W images, and there was diagnostic values of tail sign.Conclusion The MRI features of meningiomas have high sensitivity and characteristic feature, and most of meningiomas could be diagnosed before operation according to MRI features.
