[Abstract] Objective: To study the relationship between the atypical meningioma of MRI findings and its pathological features, analyze the reasons of misdiagnosis, to improve the diagnostic level.Materials and Methods: MRI findings of 22 cases meningioma confirmed by surgery and pathology were analyzed retrospectively. All cases were performed enhanced MRI.Results: MRI findings of all the 22 cases meningioma were as following: 8 cases were exactly like intracerebral tumors, 8 cases located at uncommon sites, and 6 cases located at conman sites. Fifteen cases showed heterogeneous signal on MRI, 12 cases had invasive boundary. Pathological grade: WHO Ⅰ grade 12 cases, WHO Ⅱ grade 4 cases, WHO Ⅲ grade 6 cases.Conclusions: The reasons for misdiagnosis of meningioma on MRI include complexity of pathological changes, biological characteristics and unexpected locations. A key point of prompting the diagnosis of meningioma is to recognize the atypical findings on MRI combined with the pathological features.
