Abstract

Herein, we present a case of a right coronary artery proximal occlusion and acute myocardial infarction with absence of the reverse attenuation gradient sign that was incidentally identified in the emergency room with non-gated computed tomography angiography of the aorta performed to rule out aortic dissection. This case highlights the importance of assessing the heart and coronary arteries even on non-gated computed tomography angiography.
