Figure 2 A 55-year-old woman with pathologically confirmed solitary fibrous tumor (orange arrow) in the liver, which is closely adjacent to the inferior vena cava (the red arrow). Preoperative MR examination suggests the tumor shows (A) hypointensity on T1-weighted imaging, (B) hyperintensity on fat-suppressed T2-weighted imaging, (C) exhibits restriction on diffusion-weighted imaging (b=800), and (D) apparent diffusion coefficient images. Dynamic contrast-enhanced MRI reveals that (E) the lesion with arterial phase hyperenhancement followed by (F) washout in the portal phase. (F–H) Persistent peripheral rim enhancement is noted in the portal, venous, and delayed phases. (I) On hepatobiliary phase imaging, the lesion is hypointense compared with the background liver parenchyma and contains an internally hypointense scar.
