Aspergillus pseudoaneurysm of the ascending aorta is rare in patients who have undergone coronary artery bypass graft surgery (CABG), and there are few cases reports of patients with AIDS, or after transplantation. A 76-year-old man underwent CABG due to unstable angina in 2002 ; in 2005 and 2006, he suffered 3 episodes of pseudoaneurysm formation in the ascending aorta. The aneurysm was resected and the defect was repaired with a Dacron patch twice. Finally, aortic root replacement with the modified Bentall technique was performed, but pathological examination of the wall of the pseudoaneurysm showed Aspergillus. On day 13, the Aspergillus infection developed into septicemia, and he died.
