[Acute jaw-thoracic pain and syncope in a 41-year-old man].

A 41-year-old physically active man with no significant past medical history presented with sudden thoracic pain. The patient was referred to the next tertiary care hospital. A CT scan showed an ectasia of the ascending aorta with irregularities of the aortic wall without dissection. Despite initial refusal, the patient was referred to a university hospital with experience in aortic surgery. A triphase ECG-synchronized cardiothoracic flash protocol performed on a 256 line CT scanner confirmed an aortic intramural hematoma and a covered aortic perforation. Shortly afterwards the patient collapsed and had to be resuscitated.
