Abstract
Mycotic aneurysms, often saccular, accounting for approximately 2.5% of all abdominal aortic aneurysms, possess increased risk of rupture, uncontrolled sepsis, and protracted hospital stay and are associated with high morbidity and mortality. The authors report the case of a 49-year-old female with no known comorbidities who presented with free rupture of an infrarenal dissecting mycotic aneurysm and underwent emergent open repair successfully. The etiological agent, Brucella melitensis , a Gram-negative zoonotic coccobacillus, is rarely reported to cause mycotic aneurysm.
Highlights
Often saccular, accounting for approximately 2.5% of all abdominal aortic aneurysms, possess increased risk of rupture, uncontrolled sepsis, and protracted hospital stay and are associated with high morbidity and mortality
Free rupture of infrarenal abdominal aortic aneurysm is a catastrophic event leading to imminent mortality, unless expeditiously intervened
The term “mycotic” was coined by Sir William Osler[1] in 1885. This is a misnomer since not all infective aneurysms are caused by fungi
