Summary:

Description
  • Radiopaedia case ID: 27746
  • Image ID: 5942398
  • Image stack position: 51/155
  • Plane projection: Axial
  • Aux modality: C+ arterial phase
  • Study findings: The CT confirms hematoma around the ascending aorta and aortic root, associated with intimal irregularity and outpouching in the left aspect of the ascending aorta, but without an enhancing false lumen or intimal flap. There is a small hemopericardium.  The descending, thoracic and abdominal aorta demonstrate atheromatous calcification but otherwise demonstrates contrast enhancement and normal caliber. In the chest, there is bibasal atelectasis and prominent upper lobe pulmonary vasculature. No pleural effusion identified. The tip of the endotracheal tube lies 3 cm from the carina. No mediastinal free gas identified. Comment The hematoma around the ascending aorta and aortic root, with associated intimal irregularity at the ascending aorta and small hemopericardium, is compatible with a Stanford type A aortic dissection with thrombosed false lumen. The differential is an intramural aortic hematoma. No distal propagation into the descending thoracic aorta noted.
  • Modality: CT
  • System: Vascular
  • Findings: A widened mediastinum was noted, although an AP projection it was wide enough to evoke suspicion of an aortic dissection.
