Figure 4.
Right ventricular thrombus and COVID-19 pneumonia in a 62-year-old man with hypoxia and markedly elevated d-dimer levels (>50 000 ng/mL). Axial chest CT angiographic image shows a well-circumscribed hypoattenuating filling defect within the lumen of the right ventricle, indicative of a thrombus (solid arrow). Patchy lung opacities (dashed arrows) related to COVID-19 pneumonia are only vaguely depicted, owing to the window settings used.
