Non-contrast CT of the chest demonstrates hyper-densities within both central and sub-segmental pulmonary arteries bilaterally (see yellow arrows). The right ventricle is dilated.
In the lateral view chest x-ray, there is a Hampton’s Hump, a pleural based, wedge-shaped opacity at the base of the right lung, representing lung infarction (black arrow). These findings correlate with the sagittal view on CT angiography of the chest. The CT chest also shows a filling defect in the distal posterior basal segmental pulmonary artery (white arrow), as demonstrated by the absence of contrast enhancement in the distal portion of the vessel. This is associated with an opacification of the lung parenchyma distal to the occlusion (red arrow), representing lung infarction.
