a Plain computed tomography (CT) scan showed a 13.6-cm low-density mass in left hepatic lobe. b Dynamic CT arterial phase scan shows enhanced edge of the mass with non-enhanced interior. c Low-density area remained in the equilibrium phase. d Fluorodeoxyglucose-positron emission tomography (FDG-PET) demonstrated a high FDG uptake (SUVmax 4.9) in the peripheral region of the mass
