A Case of an Infected Aneurysm in the Thoracic Aorta Mimicking Tuberculous Lymphadenopathy

Tuberculous-infected aortic aneurysms are rare, but delayed diagnosis can lead to serious complications, including sudden aortic rupture. Here, we report a case of a tuberculous infected aneurysm in the thoracic aorta that was mistaken for lymphadenopathy. In this case, we could differentiate the lesion with the aid of contrast-enhanced computed tomography and positron emission tomography (PET). This case demonstrates the diagnostic value of PET in aortic aneurysms. (Korean J Med 2015;89:323-326)
