Intracranial solitary fibrous tumor(SFT)/hemangiopericytoma (HPC) is a rare malignant tumor originating from the intracranial vasculature, while Angiomatous meningioma (AM) is also a rare benign one as a histological subtype of meningioma with World Health Origination (WHO) grade I. The two tumors have similar location and conventional MRI features, but the treatment and prognosis are quite different. Texture analysis can get more information that can't be seen in conventional MRI images. It is very necessary to establish the differentiation model of texture analysis between the two kinds of tumors.
