CT and CTA Diagnosis Of Intracranial Hemangiopericytoma / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the CT and CTA findings of intracranial hemanigoperiocytoma. Materials and Methods The CT and CTA data of 7 cases of pathologically confirmed intracranial hemanigoperiocytoma were retrospectively reviewed. Results All the 7 cases were extra-axial and supratentorial location. Six were lobulated and 1 were oval in shape. Three were iso-density to the parenchyma and 4 were inhomogeneous with clear margins. Five had perifocal edema. On contrast scan, all showed homogeneous or inhomogeneous enhancement. Five had dilated tortuous vessels and 4 were identified as feeding artery inside or around the tumors. Conclusion The CT findings of intracranial hemanigoperiocytoma are similar to meningioma but CTA is helpful for the differential diagnosis.
