1-10 were the same case. 1 Lesion has equal density and small circular calcifications were observed inside. 6-7 Mass on the fat suppression and DWI (b = 800) showed obviously high signal with small blood vessel shadows inside. 2-3 and 7-10 In the arterial phase, in the center of the lesions, there is the nodular enhancement. As time goes by, the enhanced range was expanded and showed a “fast in and slow out” performance. 4, 8 In the arterial phase, aberrant draining veins filled by the contrast agent antidromic could be observed, which were connected to the left brachiocephalic vein
