CTICasesPulmonary embolism and chronic occlusion
Imaging findings
Contrast-enhanced CT shows a peripheral filling defect in a pulmonary artery branch with adjacent pulmonary infarction. Follow-up CT two months later shows near-complete contraction of the vessel to a thin, fibrous cord with complete lack of recanalization.
Key takeaways
While most acute pulmonary emboli undergo fibrinolysis and recanalize, some can lead to permanent vessel occlusion, where the vessel and thrombus contract over months into a thin, fibrotic, non-recanalized cord.
