2. Figure 1
Contrast-enhanced computed tomography (CT) images identified ectasia and circumferential mural thickening of the descending thoracic aorta. A, An axial image is provided. B, This is the sagittal view. C, A coronal view also was obtained. Severe stenosis at the level of the diaphragmatic hiatus is marked with an arrow. D, A maximum intensity projection magnetic resonance image also demonstrated severe stenosis of the descending aorta.

3. Figure 2
A, Volume-rendered CT imaging of the left anterior descending coronary artery demonstrated a large amount of diffuse plaque with focal narrowing in multiple areas (arrows). The findings implied vasculitis. B, Multiplanar reconstruction CT imaging indicated the same. C, This is another multiplanar reconstruction CT image.

A, Whole body positron emission tomography (PET) with fludeoxyglucose-18F (FDG) disclosed increased uptake of the contrast agent within the bone marrow of the spine and pelvis and in the right axillary (arrow) and supraclavicular lymph nodes. B, No FDG uptake was evident in the aortic wall on a fused PET-CT image.
