case_images: Multiple CT scan cuts of the neck and chest with IV contrast showing an aberrant right subclavian artery. This axial CT scan illustrates a case of dysphagia lusoria with an aberrant right subclavian artery (arrowhead) originating from the right side of the aortic arch (star) (Figure A) and coursing posteriorly and laterally, compressing the esophagus (circle) (figures B and C). The anomalous course of the subclavian artery is seen causing an external indentation of the esophageal lumen, which is a classic feature of dysphagia lusoria. Additionally, there is a 2-cm thoracic aneurysmal dilatation of the aortic arch (double-headed arrow) (figure D) and the proximal segment of the right subclavian artery, with associated peripheral non-occlusive mural thrombus extending into the right subclavian artery (figure B). The thrombus is seen adhering to the inner wall of the artery but does not obstruct the lumen.

case_images: These findings confirmed the diagnosis of dysphagia lusoria, with esophageal compression resulting from the thrombosed and dilated aberrant artery (Figure 3).
