After the operation, periodic follow-up CT was undertaken every 6 months and fluorodeoxyglucose-positron emission tomography (FDG-PET) was performed after 1 year of operation in order to check for recurrence of lung cancer, and the results showed no recurrence or distant metastasis and no abnormality of the thoracic aorta or unexpected mural thrombus (Fig. 1a). However, an aortic thrombus was incidentally detected in the descending aortic arch 1.5 years after the primary operation (Fig. 1b). Follow-up CT showed the aortic thrombus was gradually regressing and was eliminated completely after 6 months of anticoagulant therapy without major complications (Fig. 1c).
