Pyogenic discitis revealing infrarenal aortic prosthetic graft infection impinging on the left ureter.

Coexistence of aortic lesions and discitis is uncommon but potentially fatal if the diagnosis is not made promptly. We report the case of a 71-year-old patient with an infected prosthetic graft of the abdominal aorta impinging on the left ureter and accompanied with lumbar discitis. This triad has not been reported previously. Other unusual features in this patient were the circumstances of onset and the development of the infection in a vascular prosthetic graft. The medical and surgical treatment is discussed.
