ABSTRACT
Objective To study the CT and MRI features of meningiomas at special locations.Methods CT and MRI findings of meningiomas at special locations (lateral ventricle,diaphragma sellae,frontal sinus) in 11 cases confirmed by pathology were analyzed retrospectively.8 patients were evaluated with MRI,3 patients were evaluated with CT.Results 11 cases were all singular lesion.The lesions were at lateral ventricle in 4, at diaphragma sellae in 4,at frontal sinus in 3.Of total 11 cases,8 cases showed isointensity or slight hypointensity signal on T 1WI ,tumors had isointensity or slight hyperintensity signal or slight hypointensity signal on T 2WI,homogeneous or inhomogeneous enhancement were found on Gd-DTPA enhanced MRI scanning.3 cases were showed homogeneous density or slight highly density on plain CT scanning.Pathological diagnosis was as followsfibroblastic type in 4,angioblastic type in 3,syncytial type in 1,psammomatous type in 3.There were 9 cases were misdiagnosed before operation.Conclusion It is a fact that improving the imaging correct diagnostic rate of meningioma at special locations will play an important role in deciding correct operative route of entry and increasing cure rate.
