摘　　要：目的探讨脑膜瘤的影像学特征与病理诊断之间的关系。方法对108例脑膜瘤的影像学资料及病理学资料进行了观察和分析。结果脑膜瘤的瘤周水肿、肿瘤形态、瘤-脑组织界面、肿瘤钙化及瘤内坏死或出血等影像学特征与脑膜瘤的良恶性有密切关系,并且合体型与纤维型脑膜瘤瘤周水肿率差异具有显著性,合体型与纤维型脑膜瘤中分叶形脑膜瘤所占比率差异有显著性。结论脑膜瘤的影像学与其病理诊断有密切关系,术前可根据肿瘤的影像学对其治疗和预后进行评估。Objective To study the relationship between radiological features and pathological diagnosis in meningiomas. Method The radiological and pathological data of 108 patients with meningiomas undergoing surgery in our hospital were analysed retrospectively. Results The radiological feature of meningiomas, including peritumorous edema, shape, tumor-brain interface status, and intratumorous calcification and necrosis or hemorrhage were closely related to the benign and malignant lesions of meningiomas. The peritumorous edema of fibroblastic meningioma was significantly differed in degree from that of meningoepithelial meningioma. Conclusions There is the close relationship between radiological features and pathological diagnosis in meningiomas. The curative effect and prognosis may be preoperatively evaluated by the radiological features of meningiomas.
