Abstract
An 88-year-old woman presented at a local hospital with a left femoral pulsatile mass. CT revealed saccular aneurysms with irregular intima in the descending thoracic aorta, the right common femoral artery and the left superficial femoral artery. They were 60 mm, 30 mm, and 25 mm in diameter, respectively. After referral to our hospital, multiple inflammatory aneurysms were strongly suspected by detailed examinations. Endovascular treatment including thoracic endovascular aortic repair and surgical replacement were performed by two-stage operations. After steroid therapy was started postoperatively, her c-reactive protein (CRP) value decreased. Nevertheless, the thoracic aortic aneurysm enlarged and she died due to hemorrhage. Multiple inflammatory aneurysms are extremely rare. We consider that appropriate steroid therapy and close follow-up are most important.
