Objective To study and compare the MRI imaging characteristics of intracranial hemangiopericytoma and meningioma. Methods Thirteen cases of HPC and 102 cases of meningioma which approved by operation and pathology were selected.The MRI appearances and clinical features of tumors between the two groups were reviewed retrospectively, the data were evaluated by useing χ2 test、T test、rank sum test and Logistic Rgression. Results Shape of tumor (Continuity Correctionb=7.916), signal voids of vessel in tumor (Continuity Correctionb=11.212), cystic and necrosis degeneration in tumor (Continuity Correctionb =10.992), the type of dural attachment (Continuity Correctionb=7.593), dural tail sign (χ2 =12.731) and homogeneous degree of tumor after contrast enhancement (χ2 =10.093) were significant (P﹤0.01) different in statistics between intracranial hemangiopericytoma group and meningioma group. In addition,there was significant difference (P﹤0.05) between the two groups with sex (Continuity Correctionb=4.746), T1WI signal intensity (Continuity Correctionb=5.648), T2WI signal intensity (Continuity Correctionb=6.510) and the largest diameter of tumor (P=0.034). In Logistic regression analysis, signal voids of vessel in tumor showed significant difference(P ﹤0.01) between the two groups, and cystic and necrosis degeneration in tumor、the type of dural attachment、dural tail sign、T2WI signal intensity also showed significant difference (P﹤0.05). Conclusion The MRI findings were different between HPC and meningioma, and understanding the MRI characteristic of HPC and meningioma would provide more useful imaging basis to clinic.
