Abstract: Objective To investigate the MRI features of intracranial solitary fibrous tumors/hemangiopericytomas (SFT/HPC),and to compare these findings with those of intracranial meningiomas.Methods The clinical features and MRI findings in 28 patients of intracranial SFT/HPC (SFT/HPC group)and 68 patients of meningiomas (meningiomas group) confirmed by operation and pathology were retrospectively analyzed.The indicators of two groups were compared.Results Shape of tumor,signal homogeneous,signal voids of vessel in tumor,hypointense signal nodules on T2WI and enhanded,cystic or necrosis in tumor,meningeal tail sign,changes of the nearby bone,sex,Ki-67％ level,blood lose in surgery had significant differences between SFT/HPC group and meningiomas group (all P＜0.05).Conclusion There are some differences between intracranial SFT/HPC and meningiomas.It is helpful in diagnosis and differential diagnosis through the comparative analysis of the imaging signs.
