Rapidly progressing mycotic aortic aneurysm masquerading as acute coronary syndrome

Mycotic aortic aneurysms are rare. The most common cause of a mycotic aortic aneurysm is bacterial seeding in a diseased or injured aortic intima with subsequent arteritis. Because the clinical presentation of mycotic aortic aneurysms can be quite variable, the diagnosis hence can often be quite challenging. We herewith report an interesting case study in which the patient with a mycotic aortic aneurysm presented with the clinical picture masquerading as an acute coronary syndrome. The scenario reiterates the fact that despite the availability of accurate noninvasive imaging techniques, strong clinical suspicion might be imperative for the diagnosis of mycotic aneurysms.
