Figure 1. Segmental arterial mediolysis after anti-COVID-19 mRNA vaccination. (A) An abdominal computed tomography shows stenosis and dilatation of multiple visceral arteries, including the middle and right colic arteries (green circle), omental arteries with spindle-shaped dilatation and stenosis (red circle), and left epiploic artery developing occlusion due to arterial dissection (arrow), 58 days after third injection of anti-COVID-19 mRNA vaccination. (B) Fifty-two days after symptom onset, a spindle-shaped aneurysmal structure was observed in the left gastric artery via computed tomography (arrow), while the lesions observed at initial presentation subsided. (C) Seventy-five days after symptom onset, aneurysmal dilatation of the left gastric artery spontaneously resolved (arrow).
