Mycotic Aneurysm of Infrarenal Aorta: A Case Report and Review of Literature

Mycotic or infected aneurysms are focal vascular dilatations from inflammation or infection that results in weakening of the blood vessel wall. It poses a high risk of complications such as aneurysm rupture, uncontrolled sepsis and extensive periaortic infection. Symptoms are frequently minimal during the early stages and a high index of suspicion is essential to make the diagnosis. They are more likely to expand rapidly and rupture without surgical intervention. We report a case of a middle-aged man presented with 3-week history of fever, abdominal pain and low back pain. Initially presented as acute pyelonephritis with subsequent findings of liver abscess, right epididymoorchitis and left infrarenal mycotic aneurysm, which rapidly increased in size and underwent successful endovascular surgery.
