smooth narrowing from possible external compression of the thoracic esophagus
mild esophageal dysmotility
The narrowing in the upper esophagus was favored to represent compression from an aberrant right subclavian artery and a CT chest was recommended to confirm the diagnosis.
From the case:
Dysphagia lusoria
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/51418/annotated_viewer_json?iframe=true\u0026lang=us"}
CT confirmation of an aberrant right subclavian artery passing posterior to and indenting the esophagus.
Case Discussion
The diagnosis of dysphagia lusoria in this case was suspected on the barium swallow and confirmed on CT. The aberrant right subclavian artery is passing posterior to the esophagus but may pass anterior to the esophagus, either between the trachea and esophagus or anterior to the trachea.
