Abstract：Objective To explore the characteristics and microsurgical treatment of angiomatous meningioma. Methods The clinical data of 22 patients with angiomatous meningioma undergoing microsurgical treatment were analyzed retrospectively. The clinical feature, imaging feature, microsurgical skill and prognosis were summarized. Results The T1WI MRI imaging of angiomatous meningioma demonstrated isointensity or slightly hypointensity and T2WI MRI imaging mostly demonstrated hyperintensity and showed obvious peritumoral edema and vascular flow voids. All the 22 cases demonstrated dural tail sign and extremely obvious enhancement at post-contrast imaging. The tumor was rich in blood vessels and had a rich blood supply which is from both dural arteries and cortical branch arteries. SimpsonⅠ resection was achieved in 16 patients and SimpsonⅡ in 6. There was no recurrence during follow-up period from 6 months to 2 years. Conclusions The angiomatous meningioma is dominated by vascular metaplasia and riches in blood vessels, thus demonstrating characteristic imaging findings. The tumor is extremely rich in blood supply. After totally surgical removal, the relapse rate is low.
