An expansile mass in any pulmonary vessel is more likely to be tumour rather than thrombo-embolus but especially in a pulmonary vein. In this case it appears to be a metastasis from oesophageal malignancy although in most cases such an appearance is more likely to be a feature of locally advanced primary lung cancer.
