A Case of an Infrarenal Mycotic Abdominal Aortic Aneurysm Caused by Bartonella henselae

IntroductionBartonella spp. is a highly unusual cause of mycotic aneurysms. We describe the first case of an infected aortic aneurysm secondary to Bartonella henselae endocarditis in an immunocompromised patient.ReportA 72-year-old woman presented with severe left lower quadrant pain. Computed tomography angiography showed an infrarenal mycotic aneurysm, and transoesophageal echocardiogram revealed aortic valve vegetation. Serology confirmed the presence of B. henselae endocarditis. Given the patient's comorbidities, the aneurysm was successfully treated by endovascular repair and antibiotic therapy.DiscussionEndovascular stent-grafting is an alternative treatment option for mycotic aneurysms in high-risk patients who are unsuitable for open repair
