Objective To analyze imaging features of WHO grade I, II meningiomas for a better differential diagnosis. Methods The pathological and imaging data of 137 cases of grade I meningioma and 32 cases of grade II meningioma which were treatable by surgery were studied in terms of pathological types and MRI features such as lobulated sign, necrosis and cystic change, homogenous signal intensity, homogenous enhancement, peritumoral edema, brain tumor interface, dural tail sign and adjacent bone change. Results In 169 intracranialmeningiomas, there are 137 gradeⅠmeningiomas and 32WHO gradeII meningiomas. Differences in lobulated sign, necrosis and cystic change, heterogeneous enhancement and heterogeneous signal intensity, peritumoral edema, brain tumor interface, between WHO grade I meningioma and WH0 grade II meningioma were statistically significant(P<0.05), dural tail sign and adjacent bone change were not statistically significant(P>0.05). Conclusion The MRI features such as lobulated sign, necrosis and cystic change, peritumoral edema, brain tumor interface, homogenous signal intensity and homogenous enhancement are helpful in differential diagnosis of WHO grade I meningioma and WH0 grade II meningioma.
