Pulmonary vein thrombosis as an incidental finding on contrast-enhanced CT

Case 1 is a 33-year-old man with Ewing sarcoma, pulmonary metastases, and cardiotoxicity due to neoadjuvant chemotherapy.The patient was asymptomatic, and a contrast-enhanced chest computed tomography (CT) scan was performed as a follow-up.The scan showed a filling defect representing a clot in the proximal segment of the right inferior pulmonary vein extending into the left atrium (Figure 1A-B).A diagnosis of pulmonary vein thrombosis (PVT) was made.This finding was not present six months before (Figure 1C).
