ABSTRACT
Mycotic aneurysms are rare, accounting for only 0.65% to 1.3% of all aortic aneurysms (1-3).
The natural history of mycotic aortic aneurysms is associated with significant mortality and
morbidity, which are due to delay in diagnosis, recurrent septic emboli, sudden expansion and
rupture with exsanguination. In addition any in situ prosthesis used to repair the aneurysm
may become secondarily infected, compounding the problem (Figs. 1A,B and 2).
