Abstract:
A 60-year-old man presented with chest discomfort with fever and high C-reactive protein (CRP). Chest computed tomography (CT) disclosed a mediastinal soft tissue swelling originating from the aortic arch, and gallium-67 single-photon emission CT revealed intense uptake in the same region. We initially suspected mediastinitis and/or a thoracic aortic infection. Antibiotics improved his symptoms and CRP levels. However, a follow-up CT scan 33 days later, revealed an aortic arch aneurysm and the patient was diagnosed with infective aortic aneurysm. Here, we report a rare case of a rapidly progressing aneurysm of infected aorta aortic infection with pseudoaneurysm formation.
