Each year, 1.4 million people in the United States are infected with Salmonella (Beneson et al. [23] Am J Med, 110:60–63, 2001). The most common clinical presentation of Salmonella infection is gastroenteritis which is usually self-limited, lasting between one to four days (Black et al. [24] N Engl J Med, 261:811–816, 1960). Although most infections are mild-to-moderate, serious disease, and death does occur (Voetsch et al. [25] CID, 38:S127–S132, 2004). A rare but increasing number of patients present with Salmonellosis spondylodiscitis resulting from contiguous spread of infection from the adjacent abdominal aorta. Concurrent infection of these structures exacerbates morbidity, necessitating an elevated clinical suspicion in patients with appropriate risk factors, clinical signs and symptoms. Furthermore, an overall mortality rate of 67 % makes mycotic abdominal aortic aneurysms highly lethal (Gonda et al. [26] Radiology, 168:343–346, 1988). Thus, early diagnosis is crucial, allowing for prompt antibiotic and surgical management. Laboratory and imaging tests obtained at the initial suspicion for infection of the spine and aorta facilitates diagnosis while minimizing or preventing more serious complications like paresis and aortic rupture. We present a patient with a mycotic abdominal aortic aneurysm infected with Salmonella enteritides that spread to the adjacent lumbar vertebra and left psoas muscle.
