Brucellosis relapse causing thoracic aortic ulcers and aneurysm formation: a case report

Background Brucellosis is an infectious disease caused by Brucella spp, which can involve the cardiovascular, digestive, and respiratory systems. Cardiovascular involvement is a rare occurrence, it has an extremely high mortality rate. Case presentation A 67-year-old Chinese man presented with thoracic aortic multiple ulcers and partial aneurysm formation that caused symptoms of left waist and left buttock pain. The man was admitted to our hospital due to abdominal aorta pseudoaneurysms 5 years ago. The diagnosis was made by thoracic computed tomography angiography (CTA), previous history, and positive culture of Brucella, and the patient was successfully treated by thoracic aortic covered stent-graft implantation and specific medical treatment. Conclusions People who have a history of contact with cattle and sheep, should beware of the possibility of Brucella infection. If chest and abdominal pain occur, timely medical treatment is recommended, aortic aneurysm, the disease with a high risk of death, can be identified or excluded by CTA. Early treatment and prevention of disease progression are more beneficial to patients.
