Calcified pulmonary embolus
Pictorial
review of the pulmonary vasculature: from arteries to veins. Two patients with chronic pulmonary emboli. a Axial contrast-enhanced CT image shows a web-like filling defect within a segmental right lower lobe pulmonary artery consistent with chronic pulmonary embolus (white arrow). b Axial non-contrast CT image of another patient demonstrates linear calcification within the right interlobar pulmonary artery consistent with chronic pulmonary embolus (white arrow)
Calcification associated with pulmonary emboli is usually associated with chronic pulmonary embolism. Calcification is occasionally related to prior congenital cardiac repairs .
