We present a rare double aortic arch (DAA) diagnosis incidentally on CT in a 60-year-old male who presented with pneumonia. DAA is a vascular ring that typically manifests in infants or children due to compression of the esophagus or trachea, resulting in dysphagia or dyspnea. Diagnosis of DAA in adulthood is usually due to the delayed emergence of obstructive symptoms. We present a case of DAA in an adult patient without dysphagia or dyspnea. We discuss factors that can lead to the presentation of DAA in adults. These include an absence of associated congenital disabilities, insufficient tracheal or esophageal constriction in childhood and the onset of compressive symptoms later in life from decreased vascular compliance.
