Although Salmonella infection is a common etiological factor for mycotic pseudoaneurysm, Salmonella paratyphi A infection causing mycotic pseudoaneurysm is extremely rare. Endovascular therapy has been described as a feasible treatment for mycotic pseudoaneurysm.Case Presentation: A 63-year-old female patient had a thoracic aortic pseudoaneurysm caused by Salmonella paratyphi A infection. The patient associated with diabetes had a fever, abdominal pain, and low back pain, who was successfully treated using endovascular stents treatment and antibiotics.Conclusion: Salmonella paratyphi A is a bloodstream infection bacterium with the ability to cause mycotic pseudoaneurysm. To treat mycotic pseudoaneurysms of the thoracic aorta, endovascular stent-graft treatment combined with antibiotics is an alternative treatment for patients who cannot tolerate open surgery.Keywords: infectious pseudoaneurysm, bloodstream infection, endovascular treatment, antibiotic
