Salmonella 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.
The 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.
This case highlights the importance of considering the diagnosis of a mycotic aneurysm in an unusual presentation of back pain with features of infection.
沙门氏菌属通常会导致人类感染，偶尔会导致严重的并发症，如真菌性动脉瘤。在此，我们报告首例可能由里森沙门氏菌感染引起的真菌性动脉瘤患者。
患者因下背部疼痛、寒战和 2 个月前在香港和台湾旅行 14 天期间出现的单次腹泻就诊，病程为 4 周。磁共振成像显示左侧髂内动脉呈动脉瘤样改变，邻近左侧髂腰肌边缘增强性积脓。全基因组测序显示粪便培养出沙门氏菌里森 ST469 EBG66。患者接受了紧急分叉式髂内动脉瘤修复术，并成功地用适当的抗生素进行了治疗。
该病例强调了在背痛不典型表现伴感染特征的情况下，应考虑真菌性动脉瘤的诊断。
