[Abstract] Objective: To compare and analyze imaging features of intracranial hemangiopericytoma(HPC) and Solitary fibrous tumour(SFT).Materials and Methods: Eighteen patients of HPC and 10 patients of SFT proved by operation and pathology were analyzed retrospectively. Both plain and enhanced MR scans were performed and the results were analyzed in all cases.Results: There were no significant difference between HPC and SFT in relation to the attachment of the dura mater, dural tail sign(P>0.05). The difference between the two groups were significant difference, in relation to tumor shape, T2WI signal, necrotic and cystic areas and hemorrhage, peritumoral edema, skull destruction, enhancement(P<0.05).Conclusion: Imaging findings of intracranial HPC and SFT are different, the former has mostly lobulated, irregular shape, iso-high signal on plain T2WI, cystic necrosis and hemorrhage more common, obvious peritumoral edema, visible skull destruction, significant enhancement; the latter is mostly round or oval, low signal area on plain T2WI, rare cystic and necrosis, hemorrhage, light peritumoral edema, no skull destruction, significant enhancement with delayed enhancement.
