Abstract：Objective To investigate the clinical manifestation , MRI and pathology features of microcystic men-ingiomas .Methods Six patients with pathologically confirmed microcystic meningioma were retrospectively reviewed . Results The common location of microcystic meningioma was similar to the other type of meningiomas .The tumors fre-quently exhibited low density on CT scan .On the MR scan, the tumor was characterized with non -uniform enhancement on the Gd enhanced T1W1 weighted MR.Moreover, 3 tumors were confirmed to be supplied with both brain and extra -brain vessels .Pathologically , the tumor cells lined gyrately and sparsely , where axons went cross to form various micro-cysts.The nucleolus division was seldom seen and the percentage of positive of Ki -67 staining was very low.The tumor was featured with positive staining of vimentin and PR , but negative of GFAP .Conclusion Microcystic meningiomas had some distinctive features on CT and MR scan from the other type of meningiomas .Surgical operation is the first line treat-ment for them, and intensive follow -up is warranted.
