Fig. 2. MRI shows an irregularly shaped, 4. 9 × 4 Fig. 2. MRI shows an irregularly shaped, 4.9 × 4.5 cm sized, low signal mass on T1WI (a) and several, dot-like, high signals (arrows), suggesting internal hemorrhagic foci within a mass. The mass shows high signal intensity on T2WI (b). The central portion of the mass shows early dynamic-phase enhancement (c) and a washout pattern on the delayed phase (d). The periphery of the mass shows persistent trapping of contrast medium in the irregular enhancing portion and surrounding edema. Large, draining vessels (arrowheads) around the mass are well seen on MIP imaging (e). PET-CT (f) shows the inhomogeneous FDG uptake (SUV = 2.2−2.9) of the mass. Fig. 2.
