FIGURE 1 A. Axial unenhanced T2 weighted image shows a well-defined
heterogeneous hyperintense mass with hypointense rim. B. Contrast
enhanced arterial phase fat saturated T1 weighted image demonstrates the
lesion as hypointense. C. On a contrast-enhanced portal phase fat
saturated T1 weighted image, the lesion demonstrates heterogeneous
enhancement.
