ABSTRACT
Purpose:
To assess MRI and MRS features of intracranial hemangiopericytoma.Materials andMethods:
The imaging data of MRI and MRS were analyzed retrospectively with seven cases of hemangiopericytoma.MR examinations were performed on seven cases,MRS on 4 cases.Results:
The position of lesions were all located at the supratentorial area and extraaxial region.Six masses were lobulated in shape.Of seven cases,3 cases were isointense with cortical gray matter,3 iso- and hypointense,l hypointense with localized hyperintense resulted from hemorrhage on T1WI 2 cases demonstrated isointense with cortical gray matter,4 iso- and hyperintense,1 complex hyperintense on T2WI.Five tumors had prominent internal or surficial serpentine signal voids.3 tumors showed homogeneous marked enhancement,4 heterogeneous enhancement.MRS of four tumors showed marked elevated Cho peak,Lip peak and diminished or disappeared NAA peak.Two cases were companied with marked elevated MI peak.Conclusion:
The MR imaging findings of hemangiopericytoma has some characteristics,which can help differentiation from meningioma combined MRS.
