Imaging findings of the patient. Computed tomography (CT) scan showed an ill-defined, hypodense mass in the right liver lobe extending to the diaphragm (A) with moderate enhancement in the periphery of the mass at 54 s (B), 84 s (C) and 200 s (D) after intravenous injection of contrast. Magnetic resonance imaging (MRI) demonstrated an elliptic mass in the right liver lobe with an increased signal on both T1- (E) and T2- (F) images; On T2- SPAIR sequence the mass showed high signal indicating haemorrhage within the mass (G); H Post-contrast axial T1-weighted sequence showed the capsule of the right lobe of liver was unevenly thickened and enhanced but no obvious enhancement was visible inside the tumor
