Endovascular treatment of thoracic aortic pseudoaneurysm due to brucellosis: a rare case report

Background: Arterial damage is a known complication of brucellosis, but the occurrence of a thoracic aortic pseudoaneurysm secondary to brucellosis has not been previously reported. Case presentation: A 65-year-old Chinese man presented with a pseudoaneurysm in the descending segment of the thoracic aorta that caused symptoms of chest pain and intermittent fever. He was diagnosed with a thoracic aortic pseudoaneurysm secondary to brucellosis based on a positive brucella serology test (standard-tube agglutination test) and imaging examination (computed tomography angiography). Anti-brucellosis treatment and covered stent graft implantation were attempted to eliminate the brucellosis and pseudoaneurysm, respectively, and were ultimately successful, with no symptoms after 6 months of follow-up. Conclusion: Endovascular repair may be effective and safe for treating a thoracic aortic pseudoaneurysm resulting from brucellosis.
