Pulmonary Septic Emboli due to Azygos Vein Septic Thrombosis
Computed tomography of the chest (panel (a): coronal view—lung window): multiple pulmonary cavitary lung lesions due to septic pulmonary emboli (arrows). Panel (b) (axial view—lung window) and panel (c) (axial view—mediastinal window) show multiple cavitary lung lesions due to septic pulmonary emboli (arrow heads). Filling defect is noted in the azygos vein suggestive of venous thrombus (arrow in panel (c)). There is associated mild pleural effusion bilaterally.
