Bacterial aortitis is a rare but serious condition. Even when treated surgically, the prognosis is poor. Prompt diagnosis is mandatory. In the absence of specific clinical signs, radiological assessment by means of ultrasound and CT is most valuable. The treatment of choice is early surgical drainage, debridement and arterial reconstruction, preferably through uncontaminated tissue combined with antibiotic therapy. We report the case of a man aged 80 with Salmonella aortitis in whom the diagnosis of bacterial aortitis was made by means of ultrasound and CT, following which successful intervention was carried out.
