Objective To investigate the imaging features of magnetic resonance imaging (MRI) of intracranial hemangiopericytoma (HPC). Methods From January 2013 to January 2018, 23 HPC patients (HPC group) were treated in our hospital, and 70 patients with hemangioma meningioma were selected as the control group (meningioma group), two groups of MRI imaging features were compared. Results In 23 cases of HPC, 14 cases were high differentiation HPC, 9 cases were anaplastic HPC. The lobulated tumor morphology, tumor necrosis and cystic degeneration, tumor showed narrow basement attach to the dura, T2WI showed equal high signal, tumor enhancement ratio in HPC group were 65.22%, 69.57%, 65.22%, 73.91% and 91.30%,were higher than that of meningioma group (P<0.05), the ratio of tumor necrosis and cystic degeneration in anaplastic HPC was 100.00%, higher than the high differentiation HPC (P<0.05), the difference in tumor morphology, dural tail sign, the relationship between tumor and attachment dura, T1WI signal, T2WI signal and the degree of tumor enhancement between anaplastic HPC and high differentiation HPC were no statistical significant (P>0.05). Conclusion The MRI image of intracranial HPC has some characteristic features, and there are certain differences in the MRI image of different differentiated HPC.
