摘　　要：目的探讨颅内孤立性纤维瘤(SFT)/血管外皮瘤(HPC)MRI影像征象,并与脑膜瘤进行对比分析。方法分析经手术和病理证实的SFT/HPC患者28例(SFT/HPC组)和脑膜瘤患者68例(脑膜瘤组)的临床及MRI征象,并比较各观察指标。结果肿瘤形态、信号均匀性、瘤内血管流空信号、瘤内短T2信号强化结节、瘤内囊变坏死情况、脑膜尾征、骨质改变、性别、Ki-67%水平、术中出血量在两组间差异均有统计学意义(P均<0.05)。结论 SFT/HPC及脑膜瘤临床及MRI表现存在一定差异,对比分析两者的影像征象有助于两者的鉴别诊断。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.
