CTICasesDiffuse Coronary Artery Ectasia of Unclear Etiology
Imaging findings
A calcium score CT revealed diffuse ectasia of the coronary arteries, including notable enlargement of the RCA and obtuse marginals. While some mild atherosclerosis was present, the appearance was not typical for extensive atherosclerotic aneurysms. The aorta and pulmonary arteries were normal, and there was no evidence of other systemic vascular or connective tissue disorders.
Key takeaways
Diffuse coronary artery ectasia can be an incidental finding, even in relatively young patients with atypical chest pain. While some degree of dilation can be associated with atherosclerosis or conditions like Kawasaki disease, this entity presents as widespread, diffuse dilation without clear etiology. Marfan-like syndromes were excluded in this case due to a normal aorta and lack of systemic features.
