[Abstract] Objective: To explore the MRI typing of microcystic meningiomas and improve the understanding of this disease.Materials and Methods: Twenty cases microcystic meningiomas confirmed by surgery and pathology was retrospectived analysis, 20 cases were performed by MRI plain scan and MRI enhanced scan in 16 cases.Results: Of the 20 cases, 9 cases (40.9%) were type 1 and 5 cases (22.7%) were type 2, and 6 cases (27.2%) were type 3. Nine cases type 1 were solid mass, low signal on T1 weighted image, and high signal on T2 weighted image. MRI enhanced scanning showed significant uniform enhancement of tumors. Five cases type 2 showed that similar cystic masses, significant low signal on T1 weighted image, significant high signal on T2 weighted image, MRI enhanced scanning tumor showed grid, flake, and radiation mild enhancement, of which 2 cases cystic non-enhanced areas at the edge of the tumor. Six cases type 3 were cystic solid masses, the solid area showed that a slightly lower signal on T1 weighted image, and slightly higher signal on T2 weighted image, the cystic area showed a low signal on T1 weighted image, high signal on T2 weighted image, enhanced scan the solid part of the tumors was significantly enhanced, the cystic part was not strengthened, and the cyst wall was slightly strengthened.Conclusions: MRI typing of microcystic meningioma has its respective characteristics, of which type 2 MRI finding was the most characteristic.
