Hepatocellular carcinoma with IVC tumour thrombus, direct invasion of the right atrium and embolic tumour thrombus. a Contrast-enhanced coronal CT depicts direct invasion of the HCC (arrow) into the right atrium. b Axial CT chest shows subsegmental right pulmonary artery dilatation with internal filling defect (arrow), likely due to embolic tumour thrombus. c Axial CT shows multifocal arterial enhancement in the liver, predominantly in segment 7 and 8. The IVC tumour thrombus also demonstrates arterial enhancement (arrow), d is visualised as a partial filling defect (arrow) in portal venous phase, and e shows intermediate T2 signal (arrow) with extension into the hepatic IVC via the middle hepatic vein
