Once bitten, twice shy: an unusual case report of a mycotic aortic aneurysm.

Primary mycotic aneurysms of the aorta are a rare, but potentially lethal condition comprising less than 1% of all aortic aneurysms. All age groups are affected but patients younger than 50 years are most susceptible. Organisms commonly implicated in aortitis and mycotic aortic aneurysms include Salmonella species and Staphylococcus aureus(1).
