case_images: A recent CT performed in our hospital showed multiple circular low-density shadows with ring-shaped enhancement ("bull's-eye sign") in the liver, the largest one was 28mm in diameter ( Figures 1A, B ). MRI showed multiple round-like low signals on T1WI and high signals on T2WI in the liver, with well-defined and ring-shaped enhancement ( Figures 1C, D ).
