Abstract: Objective The MRI features and pathological basis of angiomatous meningioma were studied.Methods A total of 25 cases of patients with angiomatous meningioma confirmed by operation and pathology were retrospectively analyzed,including the MRI examination data and the pathological data.Results There were 15 cases locating around the cerebral falx,3 cases in the cerebellopontine angle area,5 cases around the tentorium cerebelli and 2 cases in sellar region.MRIshowed a clear boundary of soft tissue masses.Intracranial lesions showed slightly low signal intensity on T1WI and high signal intensity on T2WI.The space-occupying effect was obvious,but the tumor edema was light.Multiple abnormal flowing void phenomenon was visible in intratumor tissues.MRI enhancement scanning showed the solid tumors were significantly enhanced.Conclusion The incidence of angiomatous meningioma is very low,but MR performance has a certain characteristics,so MRI can facilitate the positioning and qualitative diagnosis of the disease.
