Abstract
Objective: To explore the MRI differences between intracranial anaplastic hemangiopericytoma (HPC) and angiomatous meningioma. Materials and Methods: There were sixteen patients with HPC and twenty four patients with angiomatous meningioma proved by operation and pathology. The imaging data about preoperative MRIs and enhancements of them were analyzed retrospectively. The imaging characteristics of these tumors were analyzed with chi-square test (χ2) and two independent sample t-test, with P<0.05 for the difference statistically significant. Results: The length of the tumor (t=2.066, P=0.046), lobulation (χ2=7.111, P=0.008), T1WI signal (χ2=17.220, P<0.001), T2WI signal (χ2=22.247, P<0.001), iso-low signal in DWI (χ2=4.310, P=0.038), cystic necrosis (χ2=7.111,P=0.008), the degree of peritumoral edema (χ2=9.864, P=0.014), signal void of vessel (χ2=8.087, P=0.004), subdural connected with a narrow base (χ2=15.973,P<0.001) ware statistically significant (P<0.05) between HPC and angiomatous meningioma. Meningeal tail (χ2=0.150, P=0.698), Intratumoral hemorrhage (χ2=2.338, P=0.126), brain midline shift (t=–1.656, P=0.106) showed no statistical differences (P>0.05). Conclusions:There are differences in MRI findings between HPC and angiomatous meningioma. It is helpful for the diagnosis and differential diagnosis through the comparative analysis of the imaging signs.关键词
