case_images: (A) Early phase aortogram in the anteroposterior view
  demonstrates no opacification of the celiac artery
  representing complete occlusion, very limited
  opacification of the right renal artery consistent with
  complete occlusion at the origin (white solid arrow), long
  segment stenosis of the superior mesenteric artery (white,
  dashed arrow), focal stenosis of the left main renal
  artery (asterisk), prominent inferior mesenteric artery
  with arc of Riolan variant (white, dotted arrow) providing
  retrograde flow to the superior mesenteric artery and the
  left main renal artery. Overall, the undulating caliber of
  the aorta is noted. (B) Late phase aortogram in the
  anteroposterior view demonstrates collateral arterial
  vessels around the right kidney providing minimal
  perfusion to parenchyma and retrograde filling of the
  right renal artery (white, solid arrow), improved
  opacification of the superior mesenteric artery with
  retrograde filling from the arc of Riolan variant (white,
  dashed arrow), and slight opacification of the common
  hepatic artery (black, solid arrow) likely due to
  retrograde filling of the celiac artery branches from an
  arc of Buehler variant.

case_images: This revealed multifocal areas of large vessel occlusion and stenoses (Figure 1A and B); angiogram findings were strongly suggestive of a systemic vasculitis.
case_images: (A) Positron emission tomography computed tomography scan
  demonstrating increased fluorodeoxyglucose uptake in the
  aortic wall, most notable just above the diaphragmatic
  hiatus (arrow) consistent with inflammatory vasculitis.
  (B) Reformatted cardiac magnetic resonance posterior
  oblique image demonstrating absence of head and neck
  vessel involvement and redemonstrating abdominal aortic
  narrowing (arrow).

case_images: Her full body positron emission tomography scan showed localized areas of aortic wall thickening with increased fluorodeoxyglucose uptake in multiple areas (Figure 2A) and cardiac magnetic resonance imaging (Figure 2B), concerning for TA.
