Abstract
BackgroundSalmonella species commonly causes infection in humans and on occasion leads to serious complications, such as mycotic aneurysms. Here, we present the first case reported of a patient with a mycotic aneurysm likely secondary to Salmonella Rissen infection.Case presentationThe patient presented with 4 weeks of lower back pain, chills and a single episode of diarrhoea 2 months prior during a 14-day trip to Hong Kong and Taiwan. Magnetic resonance imaging revealed an aneurysmal left internal iliac artery with adjacent left iliacus rim-enhancing collection. A stool culture was positive for Salmonella Rissen ST 469 EBG 66 on whole genome sequencing. The patient underwent an emergency bifurcated graft of his internal iliac aneurysm and was successfully treated with appropriate antibiotics.ConclusionsThis case highlights the importance of considering the diagnosis of a mycotic aneurysm in an unusual presentation of back pain with features of infection.

Treatment and prognostic outcomes for patients with mycotic aneurysms related to Salmonella spp. are poor [5, 6]
Summary
Salmonella species commonly causes infection in humans and on occasion leads to serious complications, such as mycotic aneurysms. Conclusions: This case highlights the importance of considering the diagnosis of a mycotic aneurysm in an unusual presentation of back pain with features of infection. Whilst non-typhoidal Salmonellae infection typically presents with gastroenteritis and fever and resolves without serious complications, certain serovars may cause systemic disease, especially in immunocompromised patients [1, 3].
