The tumor was seen as a mass with peripheral nodular enhancement in the arterial phase and progressive centripetal fill-in in the portal phase of CT imaging (a). MRI showed that HSH was a hypointense mass on a fat-suppressed T1-weighted image and a mass with peripheral nodular enhancement in the early phase. In the late phase, the tumor was an iso-hypointense mass and filling defect in the hepatocyte phase of dynamic MRI. We considered the part with the contrast effect in CT or MRI as non-degenerative site (arrow) and the other part as degenerative site (arrow head). (b). The ADCmean value of the mass was 2.09 × 10−3 mm2/s on DW-MRI (c). The whitish part was shown within the hemangioma-like tumor on the liver surface and capsular retraction was identified (d). Histologically, there were many small vessels with fibrous replacement and hyalinization. The scale bar shows 1.0 mm (e)
