A 44-year-old man was injured by concreate boards falling on the left side of his body, and he was transferred to our hospital on suspicion of a blunt traumatic aortic injury. The contrast-enhanced CT axial scan showed the abnormal alignment of the brachiocephalic artery and a mediastinal hematoma. However, a 3D-CT image showed a pseudoaneurysm in the aortic arch between the brachiocephalic and left common carotid arteries. Immediately, partial arch replacement was performed. A 20 mm disruption was detected on the intimal surface of the arch aorta between the brachiocephalic and left common carotid arteries. This case was a very rare condition of blunt traumatic aortic injury.
