Dysphagia lusoria is a term utilized to describe dysphagia secondary to extrinsic vascular compression of the esophagus. The abnormal condition was described in 1794 by David Bayford in a 62-year-old female patient with dysphagia secondary to an aberrant right subclavian artery.1 It has also been associated with extrinsic compression of the aortic arch or one of its branches, with a prevalence of 0.5–1.8%.2,3 The word “lusoria” comes from the Latin phrase lusus naturae, which means “freak of nature”.3 The diagnostic method is a barium swallow test, and when there is doubt, angiotomography. Treatment depends on symptom severity and ranges from dietary modifications and alternating small bolus and liquid swallows to focusing on the cardiovascular disease causing the compression, which can include medical, surgical, or interventional radiology treatment, to obliterate or redirect the aberrant vessel.3,4 The case of an 81-year-old woman with intermittent retrosternal dysphagia to solids is presented herein. The videofluoroscopic swallow study shows extrinsic compression exactly at the level of the aortic arch (Fig. 1A and B), consistent with the diagnosis of dysphagia lusoria.
