A rare cardiovascular cause of fever of unknown origin: Infected thoracal aortic aneurysm

Aortitis can cause fever of unknown origin. Those affected patients had presented with sepsis. It is an important consideration that when we could not identify the origin of transthoracic echocardiography. However it is difficult to be revealed of descending aorta by transthoracic echocardiography. Therefore, computed tomography angiography may be kept in mind for diagnosis in patients with aortitis. We report a patient presenting to our hospital with sepsis and detected a saccular aneurysm and periaortic abscess and air collection in thoracal aorta due to Staphylococcus aureus.
