Figure 3. a–c.

A lung cancer patient with superior vena cava occlusion and perfusion change at the posterior aspect of left lobe of the liver noted on chest CT. Axial (a) and coronal (b) MIP CT images show hyperdense appearance and contrast reflux to ALGV (arrows) from collateral flow through anastomosis between pericardiophrenic and gastric veins. Axial CT image (c) of the same patient shows parenchymal hyperdensity which may mimic hypervascular lesion and focal fat spared area. Filling of ALGV leads to the diagnosis.
