Axial non-contrast CT may demonstrate only subtle findings like displacement of atherosclerotic calcification into the lumen. It would also be possible evaluate for distal complications like a high-density mural haematoma (not visible in this patient).
Axial, coronal and sagittal with contrast-enhanced CT: findings were an intimal flap with double lumen, affecting ascending aorta, arch, descending, abdominal aorta and common iliac bilaterally. At the level of supra-aortic trunks, dissection of the brachiocephalic trunk with involvement of the common carotid artery and proximal third of the internal carotid is also observed. The left common carotid artery is completely dissected. Left renal artery is dissected proximally.
