Atypical dissection of the thoracic aorta

Case contributed by Dr Erik Ranschaert

Presentation

Elderly lady who became victim of a high impact trauma, unexplained hemoglobin loss on 3d day after admission.

See the description for each serie.

Case Discussion

The intimal defect is located just distal of the left subclavian artery, which is typical for a traumatic rupture. On this level the patient also has vertebral fractures and a shoulder fracture.

The wall of the descending aorta is thickened and shows  mild concentric enhancement, the intima is displaced medially (calcifications). This means that there is a tear or hematoma in the media. Since there is no typical "flap" as seen with most type B dissections, it is considered as an "atypical aortic dissection" with intramural hematoma.
