CTICasesCoronary Periarteritis
Imaging findings
Cardiac CT demonstrates diffuse, concentric soft tissue thickening surrounding the right coronary artery (RCA), left anterior descending (LAD), and circumflex arteries. The arterial lumens are normal, and there is no pericardial effusion.
Key takeaways
Diffuse perivascular soft tissue thickening of the coronary arteries with luminal preservation can represent coronary vasculitis/periarteritis, IgG4-related disease, or Erdheim-Chester disease.
