  • Figure 1. Serial CT scans documented an ongoing process of periaortitis. (A, upper panels) Upon presentation, contrast-enhanced CT showed a homogeneous wall thickening of the aortic arch (arrow) and increased soft tissue density in the superior mediastinum. The findings were consistent with chronic periaortitis or infectious aortitis. (B, middle panels) Day 14, follow-up CT displayed a contrast-filled, mushroom-like protrusion arising from the aortic arch, about 38×22 mm, suggesting a newly developed pseudoanerysm (arrow). (C, lower panels) 12 months after operation, CT exhibiting significant resolution of perivascular infiltration and regression of aneurysmal pouch, the hyperdense stent graft in situs without evidence of endoleak
  • Figure 2. Ga-67 citrate planar imaging. (A) In initial work-up, intense activity was noted at the aortic arch (white arrows). (B) Follow up scan 4 weeks after surgery and steroid therapy, the previously described lesion at the aortic arch faded out. Linear uptake along the sternum corresponded to the surgical wound (black arrow)
  • Figure 3. Ga-67 SPECT/CT fused images. (A) Avid uptake of Ga-67 citrate on the wall of the aortic arch (arrow) on initial work-up. (B) Resolution of the previous disease process at the aortic arch 4 weeks after endovascular stent grafting
