Lusoria dysphagia in a patient with retroperitoneal fibrosis and Riedel's thyroiditis.

The case history of a 68-year-old woman with progressive dysphagia caused by extrinsic compression of the oesophagus by an aberrant right subclavian artery or arteria lusoria is presented. Previous history mentioned a Riedel's thyroiditis, idiopathic retroperitoneal fibrosis and an aortic sclerosis. The authors want to report the case because it is an example of an association between lusoria dysphagia and retroperitoneal fibrosis, the connective tissue disease responsible for Riedel's thyroiditis, and perhaps, aortic sclerosis. This is the first report of this particular association.
