Solitary fibrous tumors in abdomen and pelvis: Imaging characteristics and radiologic-pathologic correlation

Figure 3 Magnetic resonance images of a solitary fibrous tumor in the rectovesical space. A: T1-weighted Magnetic resonance (MR) image showing an oval isointense mass with patchy mild hyperintensity (arrow). The patchy mild hyperintensity was proven to be a hemorrhage; B: Fat-suppressed T2-weighted MR images reveal a mass with heterogeneous hyperintensity and patchy hypointensity; C: Contrast-enhanced MR images demonstrate moderate heterogeneous enhancement of the mass, which displaces the bladder anteriorly and rectum posteriorly (arrows).
