Objective To summarize the imaging features of intracranial solitary fibrous tumors (ISFT).Methods Ten patients with ISFT proven histopathologically were collected.Four cases had CT data and all cases had MR data.The imaging features and pathological results were retrospectively analyzed.Results All cases were misdiagnosed as meningioma at pre-operation.All lesions arose from intracranial meninges including 5 lesions above the tentorium,4 lesions beneath the tentorium and 1lesion growing around the tentorium.The margins of all the masses were well defined,and 8 lesions presented multilobular shape.CT demonstrated hyerattenuated masses in all 4 lesions,smooth erosion of the basicranial skull in 1lesion,and punctiform calcification of the capsule in 1lesion.T1WI showed most lesions with isointense or slight hyperintense signals including homogeneous in 4 lesions and heterogeneous in 6 lesions.T2WI demonstrated isointense or slight hyperintense in 2 lesions,mixed hypointense and hyperintense signals in 4,cystic portion in 2,and two distinct portion of hyperintense and hypointense signal,so called “yin-yang”pattern,in 2.Strong enhanced was found in all lesions,especially in 8 lesion with heterogeneous with the low T2 signal.“Dural tail” was found in 4 lesions.Conclusions ISFI has some specific CT and MR features including heterogeneous signal intensity on T2WI,strong enhancement of areas with low T2 signal intensity,slight or no “dural tail”,without skull thickening,and the typical “yin-yang” pattern.
