CTICasesPost-Transplant Pulmonary Vein Thrombosis
Imaging findings
CT chest shows a large filling defect (thrombus) occluding the left superior pulmonary vein and bulging into the left atrium. The left upper lobe is severely edematous with crazy paving, representing venous infarction. The patient underwent left upper lobectomy.
Key takeaways
Pulmonary venous thrombosis is a rare, life-threatening complication of lung transplantation. It causes backflow pulmonary edema/venous infarction of the affected lobe, often requiring urgent lobectomy or surgical revision.
