Abstract:
Objective To analyze MRI features of intracranial solitary fibrous tumors (SFT)and hemangiopericytomas (HPC)and combined with pathology to improve recognition of the diseases.Methods MRI and pathologic data of 13 intercranial SFT and 9 HPC were analyzed retrospectively.Results The intracranial SFT were round or oval,well-defined,with internal hypointensity and obviously enhanced area on T2and enhanced MRI-so called"yin-yang"pattern,rare hemorrhage,slight peritumoral edema and rare skull destruction.The HPC were lobulated or irregular,unclear margin,hyperintensity on T2,common hemorrhage,obvious peritumoral edema and common skull destruction.The differences between the two tumors were significant in relation to the tumor shape,T2signal,"yin-yang"pattern, hemorrhage and skull destruction(P<0.05).There were no significant differences in relation to the internal cystic necrosis,peritumoral edema, dural attachment and dural tail sign (P>0.05).Both of them showed the similar immunohistochemical features:the expression of Vim,CD34,CD99 and Bcl-2 were positive,and the expression of EMA was negative.Conclusion The MRI features of intracranial SFT and HPC are different in tumor shape,T2signal,"yin-yang"pattern,hemorrhage and skull destruction.MRI features are helpful to diagnosis and judge prognoses preliminary.
