Abstract：Objective To analyze the causes of misdiagnosis and treatment of brucella infection-induced abdominal aortic pseudoaneurysm(AAP).Methods The diagnosis and treatment process of a misdiagnosed patient with brucella infection-induced AAP in 2021 was retrospectively analyzed.Results A 35-year-old male patient presented with abdominal pain for 1 d which was aggravated for 1 h.After preliminary examination,AAP was considered and endoaortic isolation was performed.AAP appeared again at the distal end of the stent at 3 months after surgery.After follow-up,brucella infection-induced AAP was confirmed by inquiry about living and residence history,rose bengal plate agglutination test(RBPT),stand-ard tube agglutination test(SAT)and aortic CT angiography.The abdominal aorta underwent artificial vascular replacement and received standard antibiotic therapy after surgery.Misdiagnosis lasted 3 months.At 1-year follow-up,the overall condition of the patient was good,the symptoms of abdominal pain disappeared,and CT angiography showed that the artificial blood ves-sels of the abdominal aorta were smooth.Conclusion Although the incidence of misdiagnosis of brucella-induced AAP is not high currently,some patients have a greater risk of tumor rupture.Detailed inquiry into the life and residence history of pa-tients,being familiar with the clinical manifestations and imaging characteristics of aortic CTA,and early targeted laboratory examination(RBPT,SAT)and aortic CTA can help make a definite diagnosis.Standard antibiotics combined with surgical treatment is a safe and effective treatment for this disease.
