Abstract

Mycotic aneurysms are uncommon, but are fatal without appropriate management. Previous reports have shown that anaerobes and gram-negative organisms are less common but more dangerous than other causative agents of mycotic aneurysm. We report the case of a 60-year-old man with poorly controlled diabetes mellitus and atherosclerosis in the aorta, and a 10-day of history of lower abdominal pain and fever. This man was diagnosed with an uncommon abdominal aorta mycotic aneurysm caused by Bacteroides thetaiotaomicron and Acinetobacter lwoffii. The aneurysm was successfully treated with antibiotics therapy and aorto-bi-external iliac artery bypass with debridement of the infected aortic wall. We present this case together with a review of the relevant literature.

Figure

  • Figure 1 (A, B) A 2.1-cm (diameter) saccular aneurysm (arrows) with periaortic fluid collection was visible in the abdominal aorta at the L3 level.

  • Figure 2 (A, B) Enhanced computed tomography (CT) showed an enlarged (diameter from 2.1 cm to 2.7 cm) aneurysm (arrows) in a state of impending rupture.

  • Figure 3 (A, B) Postoperative computed tomography (CT) showed the successfully inserted aorto-iliac graft (arrows) and no complications.
