title: Retroesophageal aortic arch in a patient with pulmonary embolism.
abstract: The authors report an interesting case of right retroesophageal aortic arch (REAA) with pulmonary embolism that presented like the dissection of the aortic aneurysm but eventually diagnosed by means of spiral CT. Right REAA should be considered as a rare cause of mediastinal widening in the patients in whom significant difference between the blood pressure and pulse intensity of both extremities is evident to prevent the erroneous diagnosis and treatment.
