Abstract
A 66 year-old man was diagnosed as having a mycotic abdominal aortic aneurysm (MAAA) by CT and USG during examination for fever, abdominal pain and pulsatile mass. Antibiotics and antihypertensive drugs reduced inflammation and the size of aneurysm. Blood culture was negative. An anatomical reconstruction was done 13 days after the admission.
Pathological findings indicated inflammatory pseudoaneurysm. The patient's course has been uneventful for the sixteen months since his operation.
MAAA is rare and often requires emergency surgery, but in some cases cautious observation until disappearance of inflammation is useful for achieving a safer operation.
