Figure 9 Mycotic aneurysm. A: Axial contrast enhanced magnetic resonance angiography (MRA) shows large proximal descending aortic aneurysm with eccentric thrombus and invasion of adjacent thoracic vertebral body (arrow); B: Sagittal short tau inversion recovery shows large descending aortic aneurysm (white arrow) with high signal within the wall posteriorly (red arrow) indicating acute inflammation; C: Sagittal contrast enhanced MRA maximum intensity projection reconstruction shows proximal descending aortic mycotic aneurysm (arrow) extending posteriorly.
