From: Solitary fibrous tumors of the soft tissues: imaging features with histopathologic correlations
Unenhanced CT scan (A) demonstrates a well-defined heterogeneous deep soft tissue mass containing scattered hypodense areas ( thin arrows). Enhanced CTimages (B–C) display heterogeneous enhancement. MR T1W image (D) displays an isointense mass relative to adjacent muscle containing an area of relative lower intensity (white arrow) that has markedly high SI on T2W MR image (E) (black thick arrow). Heterogeneous enhancement is depicted on enhanced T1MR images (F–G). Central unenhanced areas (asterisks) on both CT and MRI exams were of low SI on MRT1W images and high SI on T2W MR image.
