A 68-year-old man was admitted with high fever and enlargement of the distal aortic arch on chest radiography. Computed tomography showed a huge proximal descending thoracic aortic aneurysm. Graft replacement of the proximal descending thoracic aorta was performed on an emergency basis, and a pectoralis major muscle flap was wrapped around the graft. Salmonella enteritidis was detected in the resected tissue. The patient recovered well, with no signs of infection.
