Primary aortoduodenal fistula: As a first presentation of brucellosis; a case report

Abstract

Introduction: The etiologies of primary aortoenteric fistula include aneurysm (most common), foreign body, tumor, radiation therapy, and infection (e.g., tuberculosis, syphilis). Brucellosis is a rare cause of primary aortoenteric fistula.

Presentation of case: In this study, we reported the case ofa 55-years-old male with an aortoenteric fistula and a positive brucellosis test.

Discussion: In regions where brucellosis is endemic, the coexistence of aortitis and aneurysm should prompt consideration of brucella infection as a relatively uncommon cause of aortoenteric fistula.

Conclusion: While aortitis due to brucellosis is rare, it can lead to life-threatening manifestations such as aortoduodenal fistula. Therefore, we recommend the use of Wright, Coombs Wright, and 2ME tests in similar cases.
