Escherichia coli primary aortitis presenting as sequelae of incompletely treated urinary tract infection.

ABSTRACT

We report a rare case of nonaneurysmal infectious aortitis (IA) with the causative microorganism being Escherichia coli. The patient was a 78-year-old man who presented with a 3-week history of abdominal pain, fevers, and anorexia after treatment for a urinary tract infection. The patient had positive blood cultures and a computed tomography scan that had signs of IA. He was treated with intravenous antibiotics and extra-anatomic revascularization with excision and debridement of the infected aortic segment with a good outcome. IA is an uncommon condition with a high mortality rate; however, if diagnosed early, it can be successfully treated.
