Background: Thoracic aortic pseudoaneurysms due to Salmonella infection are rare but life-threatening complications. Early diagnosis and effective treatment are essential to improve patient outcomes. Case presentation: We report an 82-year-old man with a history of multiple comorbidities who presented with symptoms of systemic infection, including fever and weight loss. The diagnosis was confirmed by urine and blood cultures and imaging studies, which revealed an abdominal aortic pseudoaneurysm secondary to Salmonella enterica serotype enteritidis. Intervention: The patient underwent endovascular aortic repair with a stent graft. Despite the complexity of the case due to the patient's critical condition, the procedure was successfully performed with a nearly complete exclusion of the pseudoaneurysm. Post-operative management included a prolonged course of antibiotics and monitoring for potential complications. Outcomes: The patient experienced a gradual improvement in his overall condition, with follow-up imaging showing progressive occlusion of the pseudoaneurysm. After three months he was asymptomatic and subsequent CT scans confirmed stable stent position and satisfactory aortic flow. Conclusion: This case highlights the importance of timely intervention for Salmonella-related pseudoaneurysms, especially in high-risk patients. Endovascular repair is a viable alternative to traditional surgical methods and offers a less invasive option for patients with significant comorbidities.
