title: A Subcutaneous Mass as a Sign of Thoracic Aortic Pseudoaneurysm.
abstract: A 39-year-old man on hemodialysis who received total aortic arch repair for dissection of Kommerrel diverticulum 2 months prior, visited an outpatient clinic. He presented with a sudden subcutaneous mass on the anterior chest wall 1 week earlier, that was painless, nonpulsatile, and with a normal skin color. Enhanced computed tomography revealed that the pseudoaneurysm originated from the proximal suture line. At surgery, an aortic intima was observed to be lacking at the native posterior aortic wall located at the proximal suture line with a 10-mm tear. A new graft was implanted after a new proximal suture line was reconstructed.
