A patient presented to our emergency department from another hospital diagnosed with pelvic fracture after a motor vehicle accident. In the ensuing 12 hours, chest pain developed, and a widened mediastinum on chest radiography was found. ⋯ Even though thoracic aortic injuries rarely occur in motor vehicle accidents, thoracic arch ruptures are extremely uncommon. This injury should be suspected after high-speed motor vehicle accidents, when accompanied with chest pain or widened mediastinum.
