  • Figure 1
    Abdominal ultrasonography
     

    Abdominal ultrasonography showed a well-defined heterogeneous mass situated in the right hepatic lobe. The texture of the mass was hypoechoic heterogeneous.

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Localisation; Special Focus: Acute;

    The texture of the mass was hypoechoic heterogeneous, without hypervascularization at colour Doppler, with discrete posterior reinforcement.

    Showed a well-defined heterogeneous mass in the right hepatic lobe, measuring 11 cm greater axis, heterogeneous and hypodense in spontaneous contrast.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Contrast agent-intravenous; Special Focus: Acute;

    Showed a well-defined heterogeneous mass in the right hepatic lobe, enhanced moderately to the periphery to the portal and tardy phases, including septa, with a mutilocular appearance, with liver perfusion disorders.

    Control CT after 4 weeks of corticosteroids treatment
     

    Control CT after 4 weeks of corticosteroids treatment showed a good radiological response: decrease in tumour size.
